Issue

Oxidation pond is a natural pond that relies on microbial biochemical action to degrade pollutants in water or an organic wastewater treatment pond that has been artificially trimmed. Oxidation pond treatment is one of the natural treatment methods. An oxidation pond is a small sewage treatment plant. The process of treating sewage is essentially a process of water self-purification. In the purification process, there are not only physical factors (such as precipitation, coagulation), but also chemical factors (such as oxidation and reduction) and biological factors. When the sewage enters the pond, it is first diluted by the pond water, and the pollutants diffuse into the pond water, thereby reducing the concentration of pollutants in the sewage. Then, the dissolved and colloidal organic substances in the sewage are gradually decomposed under the action of the bacteria, algae, aquatic animals, and aquatic plants that multiply in the pond, and the macromolecular substances can be converted into small molecular substances and absorbed into the microorganisms in the body, part of it is oxidized and decomposed, releasing corresponding energy at the same time, and the other part can be used by microorganisms to synthesize new organisms.

With the in-depth implementation of environmental protection work and the advancement of the modernization of farms, livestock and poultry breeding pollution has become a topic of concern to the government and society. For this reason, the state has also closed many seriously polluted livestock and poultry farms. Therefore, reducing pollution has become a survival indicator for aquaculture. The pollution of farms is mainly reflected in the direct discharge of livestock and poultry manure and urine. Therefore, reducing the pollution of livestock and poultry manure and urine has become an important measure for the development of the breeding industry.

Solution

Oxidation ponds generally use anaerobic digestion as the core technology. With the in-depth study of anaerobic theory, people have successively developed a variety of high-efficiency bioreactors, biogas digesters with fermentation and gas storage functions, and HDPE geomembrane waste liner is used. The anaerobic pond is closed.

HDPE geomembrane waste liner has the advantages of large anaerobic fermentation volume, long sewage retention period, large biogas production, and low operation and treatment costs. The construction of oxidation ponds with aquaculture geomembrane also saves sewage treatment fees.

Oxidation pond, also known as biogas slurry pond, fermentation pond. The difference with the biogas digester is that it is not covered. The purpose of the construction of the oxidation pond is to prevent the aquaculture wastewater from flowing into the ground and avoid the pollution of the groundwater. The design and structure of the biogas slurry pool are relatively simple. Before the construction of the oxidation pond, the foundation must be arranged, and the stability of the foundation determines the service life of the project. Small stones, tree roots and other things that may scratch the membrane are not allowed in the pool. It is recommended to use HDPE geomembrane waste line with a thickness of more than 1.0mm for the oxidation pond. In order to reduce the welding seam and construction period, a width of 7 meters can be selected. 7%~10% allowance (anchorage, lap joint and missing repair welding part).

Benefits

The anti-seepage geomembrane waste liner we often say is called HDPE high-density polyethylene geomembrane from the geotechnical material industry. The larger the thickness, the longer the service life, up to 50 years. It is an excellent anti-seepage material for oxidation ponds. In addition, HDPE film has high tensile strength and can be stretched more than 3 times at most. Physical properties of HDPE geomembrane waste liner are as followed.

  1. HDPE geomembrane waste liner has good anti-corrosion performance, electrical performance, moisture-proof performance, anti-leakage performance and high tensile strength, so it is very suitable for wire and cable, engineering anti-seepage, breeding anti-seepage, oil tank anti-seepage, basement Anti-seepage, artificial lake anti-seepage, landfill anti-seepage, solid waste landfill anti-seepage and other fields.
  2. HDPE geomembrane waste liner is a non-toxic, tasteless, odorless white particle of high molecular polymer, with a melting point of about 110°C-130°C and a relative density of 0.918-0.965; it has good heat resistance and cold resistance.

Advantages of HDPE geomembrane waste liner

  1. It has high-strength tensile reflection resistance: its high-quality ductility and deformation ability make it very suitable for swelling or shrinking the base surface, and can reasonably get rid of the uneven foundation settlement of the base surface.
  2. Organic chemical reliability. The geomembrane waste liner has excellent organic chemical reliability, high and low temperature resistance test, bitumen resistance, oil resistance, acid, alkali, salt and other organic chemical aqueous solutions. It is commonly used for dry wastewater treatment, chemical change pools, and waste disposal sites.
  3. Anti-aging performance. HDPE geomembrane has high-quality light fastness, anti-ultraviolet light, anti-dissolution ability, good tear resistance, anti-puncture ability, low ductility, small thermal expansion, can be exposed for application, anti-seepage for natural environment Shows very good material.
  4. Environmental protection. The basic principle of HDPE geomembrane anti-seepage is that the general physical state changes without causing all harmful substances. It is the choice for environmental protection, breeding and domestic water pools.

Summary

The following issues should be paid attention to when HDPE geomembrane is constructed in the sewage treatment pond.

  • When HDPE geomembrane is constructed in the sewage pond, is should be avoided being punctured by external force, especially when the construction is carried out at the sewage equipment, the place in contact with the sewage equipment shall be Do it well.
  • In the corners of the sewage tank or the deformed joints laid by the aquaculture geomembrane, the length of the joints should be minimized to avoid large-scale joints and cause hidden dangers to the construction quality.
  • There are two methods of welding and bonding at the joints of HDPE geomembrane. According to the terrain characteristics of different sewage treatment tanks, different welding methods can be selected.
  • The connection between the sewage treatment tank and the boundary needs to be anchored. While fixing the HDPE geomembrane, the anti-seepage quality of the sewage treatment tank is guaranteed.

Best Pond Liner to Use for Reservoir Project in Brazil

 

Best Pond Liner to Use for Reservoir Project in Brazil

Best pond liner to use for reservoir project is a kind of anti-seepage and moisture-proof waterproof building materials, and its anti-seepage performance mainly depends on the anti-seepage performance of plastic film. penetration performance.

Best pond liner to use for reservoir project is made of polyethylene resin by adding a certain proportion of carbon black masterbatch, anti-aging agent, antioxidant, ultraviolet absorber, stabilizer, etc. , it is widely used for solid waste containment, mining and water containment applications.

Case analysis

  • Location: Brazil
  • Product: 1.5mm HDPE Geomembrane Pond Liner
  • Project: Large Reservoir Project
Best Pond Liner to Use for Reservoir Project in Brazil
Pond Liner to Use for Reservoir Project in Brazil

Issue

The water storage capacity of the reservoir is 0.7Mm³, which is impounded by the filled road embankment with a height of 9m and a length of 280m. The lack of cohesive soil material on the project site meant that the dam design was based on artificial waterproofing elements, including concrete core walls and geomembranes. Early contractor engagement is client-initiated to provide constructability, schedule, and cost inputs during the conceptual design phase. A dam containing an upstream best pond liner to use was ultimately chosen for economic and constructability reasons.

The dam uses an upstream sloping HDPE geomembrane attached to the upstream toe by a concrete base on the bedrock. The geomembrane is covered with a padded and torn transition layer to provide better protection against puncture and aging.

The project site is located in an area of ​​beautiful natural beauty. The visual impact of the dam and the restoration of the surrounding area after construction are important factors for the promotion of the scheme. Planning permission was granted in June 2010 and ground surveys, profile design and energy yield studies were completed by the end of 2010. Project funders accepted the “financeable” design in early 2011, and construction began almost immediately thereafter.

A published 1:50,000 geological map of the area shows the solid geology of the Jura Quartzite Formation. the entire project. Quartzite ranges from weak to very strong, grey angular, highly fractured rocks with orange/yellow staining on some joint surfaces. Basalt is a very solid dark grey/black rock with extensive discontinuities.

Solution

The embankment has a top width of 3.5m and is set at a level of 138.0mOD with an upstream and downstream slope of 1 to 2.5. Landscaping fill is mainly placed on the lower right side to reduce the visual impact of the embankment. The waterproofing element is formed by an upstream sloping geomembrane covered with graded granular fill and ripped soil.

All peat and organic material was excavated from the dam’s footprint and temporarily disposed of at a nearby location by end dumping prior to restoration and landscaping works. The peat thickness varies throughout the dam site, with a maximum of about 2.5m, and the temporary cutting slope of the peat is roughly stable at around 1 to 1 throughout the construction period. Except for surface water discharge and filtration through straw, no special dewatering engineering bag/geotextile is required before returning to combustion. Glacier cultivated formations were trimmed and proof rolled prior to infill work.

The best pond liner to useis attached at the upstream toe to a concrete toe base cast on the prepared rock surface with a sloped concrete wedge (similar to the CFRD toe base) to provide a flat waterproofing surface to which the geomembrane is attached. The best pond liner to use is fixed on top of the anchor trench.

Best pond liner to use and installation

A 1.5mm thick dual texture HDPE geomembrane lining was chosen for the waterproofing elements. The total coverage area is approximately 50000 square meters, with mechanical seals on the upstream toe base and all ancillary structures. Special details were required to secure the geomembrane to the spillway and intake works to accommodate differential settlement of embankment fill and rigid structures on bedrock. Anchoring of the top is provided by grinding the geomembrane into the anchoring trench. The upstream embankment face was prepared by trimming and compacting the slope with vibrating plates mounted on heavy excavators. This produces a regular surface free of potholes and angular fragments of quartzite. The surface was partially masked with sand to create any local irregularities, and a 300 g/m2 “felt” type geotextile was placed on the surface, the geomembrane was spread out and fastened to the toes and tops. The geomembrane is weighed using a temporary sandbag until securely fastened and welded.

The geomembrane is supplied in 7.5 m wide rolls and all field welds are made using an automatic wide wedge welder to create double seam welds, all air tested at 2 bar pressure.

Field trials were conducted prior to installation of the geomembrane

Demonstrate that the contractor’s backfill and compaction methods do not adversely affect the integrity of the geomembrane. A section of the geomembrane was backfilled and later excavated to assess the condition of the geomembrane. The tests showed no signs of puncture or breakage and the contractor’s method of work was accepted. The geomembrane was installed in two installments to accommodate the contractor’s river diversion sequence.

Due to the relatively short length of the membrane, installation and welding were very quick, although work was temporarily suspended during high winds and rain for safety reasons.

Large Pond Lines for Sale for Dam Project in Kenya

 

Large Pond Lines for Sale for Dam Project in Kenya

CASE STUDY

  • Location – Kenya
  • Product(s) –  Large Pond Lines for Sale
  • Application – Dam Project

Issue

The dam slope is a rockfill slope. The upstream of the rockfill dam is paved with stones, which can effectively prevent the damage of upstream sediment to the dam, and the surface is troweled with simple cement. Then the customer in Kenya decided to lay HDPE high-density ethylene film on it.

Solution

Large pond lines for sale are the kind of impervious geosynthetics, which are widely used for landfill, dam, aquaculture, industrial engineering, energy engineering, mining engineering projects and so on. Large pond lines for sale have the characteristics of excellent anti-seepage performance, good chemical corrosion resistance, excellent stress cracking ability, low permeability, good UV resistance and low-temperature brittleness.

In this regard, BPM engineers used HDP geomembrane slope protection and reinforcement technology. The application principle of HDPE geomembrane slope protection and reinforcement technology in complex broken open-air slope is as follows: the anti-seepage membrane can prevent rainwater from entering the soil, prevent loose soil from affecting the strength and stability of the soil under the action of rainwater, and prevent the overall sliding caused by the reduction of mechanical parameters of sliding surface or the increase of self weight. By applying HDPE impervious membrane slope protection and reinforcement technology to the complex broken open-air slope, even if a large range of through cracks appear on the slope under the action of rain, the problem of slope sliding can be prevented.

Benefits

High density polyethylene (HDPE) large pond lines for sale has good stability, interface friction coefficient and inherent flexibility. The application of full reservoir plate waterproof in hydraulic engineering can not only make up for the deficiencies in hydraulic engineering in time, but also provide a safety guarantee for people’s life. According to the above analysis of the overall anti-seepage technology, there are many reasons for the defects of geomembrane anti-seepage technology, but in the final analysis, it is because the current technical level is not perfect, as well as the unscientific application and unprofessional personnel and other factors that the whole reservoir anti-seepage technology of geomembrane pond liner can not be well implemented. We should also avoid the quality problems caused by improper operation in the anti-seepage construction of water conservancy projects. In the specific practical application, we should select reasonable anti-seepage technology according to different geological conditions, achieve the perfect integration of materials and technology, give full play to the maximum potential of geomembrane anti-seepage technology, and make sufficient preparations for the smooth progress of water conservancy projects.

Construction method of HDPE Geomembrane Pond Liner

Before applying impermeable large pond lines for sale, the slope surface should be leveled to prevent sharp outburst, and then the loose soil should be covered with impermeable membrane.

1) It should be extended from the bottom to the high position, not too tight, and 1.50% margin should be reserved for local sinking and stretching. Considering the actual situation of the project, the slope is laid from top to bottom.

2) The two adjacent longitudinal joints shall not be in a horizontal line, and shall be staggered by more than 1m.

3) The longitudinal joint shall be more than 1.50M away from the dam foot and bending foot, and shall be set on the plane.

4) Slope first and then bottom.

5) When the slope is laid, the film spreading direction should be basically parallel to the maximum slope line.

Slope laying: before laying the anti-seepage geomembrane on the slope, the laying area shall be inspected and measured. According to the measured size, the anti-seepage geomembrane with matching size in the warehouse shall be transported to the anchorage ditch platform of phase I. during laying, the convenient way of “pushing” from top to bottom shall be adopted according to the actual site conditions. In the sector area, it should be cut reasonably to make the upper and lower ends firmly anchored.

Site bottom laying: before laying the anti-seepage geomembrane, the laying area shall be inspected and measured, and the anti-seepage membrane matched with the size in the warehouse shall be transported to the corresponding position according to the measured size. During laying, the anti-seepage membrane shall be pushed manually in a certain direction.

Alignment and alignment:The paving of BPM HDPE textured geomembrane, no matter the side slope or the bottom of the field, should be flat and straight to avoid wrinkles and ripples, so as to make the two geomembranes aligned and aligned. According to the design requirements, the lap width is generally about 10 cm.

Pressing: press the aligned and aligned BPM HDPE textured geomembrane with sand bags in time to prevent the wind from blowing and pulling. Laying in Anchorage ditch: at the top of anchorage ditch, a certain amount of impervious membrane shall be reserved according to the design requirements for local sinking and stretching.

Longitudinal joint: the uphill section is on the upper side and the downhill section is on the lower side, and sufficient lap length ≥ 15cm shall be reserved. The bentonite pad shall be laid in the area after passing the acceptance, and the manual “push paving” shall be carried out in a certain direction.

CASE STUDY

  • Location :New Zealand
  • Product(s) : 2mm HDPE Sheet
  • Application : Landfill Project

Issue

Domestic waste treatment has become a very important link in the current social development model. Whether it can achieve better domestic waste treatment and classification and achieve green and environmentally friendly working conditions is also what every region needs to pay attention to. For some refractory garbage, in the process of landfilling, it is necessary to carry out more adequate preparations to avoid leakage of garbage, which will also cause certain soil environmental pollution.

2mm HDPE Sheet for Landfill Projects in New Zealand
2mm HDPE Sheet for Landfill Project in New Zealand

Solution

The anti-seepage geomembrane liner of the landfill can ensure a more unique product environmental protection effect, and can also ensure a better product anti-seepage effect, which is also what you need to pay attention to. In recent years, under the attention of the State Environmental Protection Administration and the improvement of national environmental protection awareness, 2mm HDPE sheet treatment is adopted for environmentally friendly garbage. The role of the waste disposal site cannot be ignored by us. As early as the 1970s and 1980s, the anti-seepage membrane has been applied to the waste landfill. It will be used in waste disposal, garbage disposal and other projects Widely used impermeable membrane. The role of the anti-seepage membrane in the landfill is still relatively large, and it is the main component of the waterproof layer of the garbage disposal site. The New Zealand customer undertook the local government’s landfill project, recommended 2mm HDPE Sheet to the customer, and provided installation instructions through video. The customer is very satisfied with our products and services.

The laying method of geomembrane sheet in the landfill site

Check and measure the laying area first, and transport the film with the matching size to the corresponding position according to the measured data. Way. It should extend from the high position to the bottom, and at the same time, it should not be pulled too tightly, and a 5% margin should be reserved for local sinking and stretching. In the process of rolling and laying, it should be opened and stretched in time, and it should be in line with the slope surface and have no protruding folds. For push-laying, it should be flat and straight to avoid wrinkles and ripples. The borders should be aligned neatly, the two sheets that need to be welded should be aligned, and the overlap width should be controlled at about 15 cm.

Bonding method of landfill cover geomembrane sheet

Before bonding, remove sand, soil and other dirt on the membrane surface, and ensure that the membrane surface is clean. Using double-track hot-melt welding method:

Before hot melt welding, the upper and lower layers of impermeable membranes must be overlapped by 15 cm. The welding process is divided into adjusting pressure, setting temperature, setting speed, welding seam lap inspection, film loading machine, and starting the motor. The welds are required to be neat and beautiful, and there should be no slip welding or skipping. The temperature, speed and pressure of welding are determined by experiment and testing. The edge of the upper impermeable membrane at the welding seam should be ground into an inclination angle to improve the welding quality of the welding seam. During hot melt welding, the lap width shall not be less than 15 cm. The thickness of the weld shall not be less than 1.2 times the film thickness. On the edge of the folded portion, trim the crevice to ensure a flat overlap. When extruding welded cracks or wrinkle cut parts, the overlap should not be less than 10 cm. Cross-lap joints should be avoided, and T-shaped staggered welding should be used. The welds are required to be neat and beautiful, and there shall be no slip welding or skipping.

Anchoring method between the cover 2mm HDPE sheet and the ground: the groove anchoring method should be adopted. The anchoring groove should be separated from the construction plane by 40 cm, the groove width is 4 cm, and the groove depth is 40 cm. Pull the film into the U-shaped groove, and use sandbags or Dirt holds it in place.

Leak-proof inspection method after the covering geomembrane sheet is laid

After the landfill garbage is covered with film, it is necessary to do a good job of leak-proof inspection. If there is any problem, it can be solved in time to avoid the occurrence of leakage. In general, the inspection methods include visual inspection, inflatable inspection and damage test. Visual inspection is mainly to carefully inspect the appearance of the anti-seepage membrane laid, the quality of the weld, T-shaped welding, and substrate debris. In addition to visual inspection, vacuum detection and air pressure detection can be used if necessary. The inflation strength of inflation pressure detection is 5 minutes without air leakage. Considering that the coil is soft and easily deformed, the allowable pressure drop is 20%. When the tensile test is performed on the 2mm HDPE sheet, the standard is that when the peeling and shearing tests are performed, the weld is not torn but the mother is torn and damaged, and the welding is qualified at this time.

Benefits

  1. Reduce the infiltration of rainwater and other external water into the garbage dump to achieve the purpose of reducing landfill leachate;
  2. Control the odor emission of the landfill and the release and collection of combustible gas from the upper part of the landfill in an organized manner to achieve the purpose of pollution control and comprehensive utilization;
  3. Inhibit the reproduction and spread of pathogenic bacteria and their communicators, mosquitoes and flies;
  4. Prevent surface runoff from being polluted, avoid the spread of garbage and its direct contact with humans and animals;
  5. Prevent soil erosion;
  6. Promote the stabilization of the garbage heap as soon as possible;
  7. Provide a surface that can be landscaped, provide soil for the growth of vegetation, facilitate the reuse of landfill land, etc.

  • Application – Aquaculture Project in Thailand

Issue

Aquaculture has always been very popular in Thailand, and many local residents rely on aquaculture for a living. In Thailand, fishermen have a strict set of requirements and regulations for geomembranes used in aquaculture. Local fishermen require that each index of the pond liner must meet the American standard, non-toxic and harmless, and the use of recycled pond liner is not allowed. We found this Thai aquaculture company on Google. Then we introduced our intention to this company by email and expressed our sincerity to cooperate. Through many emails and phone calls, we learned that many local residents in Thailand have their own small fish ponds. This means that the potential of the aquaculture market in Thailand is huge. Thai customers expect us to provide geomembranes with acid and alkali resistance and anti-corrosion service life of more than seven years.

Solution

After BPM truly understood t和customer’s inherent needs, we communicate dwith the workshop technical department many times and check each size, after the production of the roll size. Our HDPE plastic sheet for fish pond products are fully capable of satisfying the aquaculture market in Thailand. Based on our experience in exporting to the Southeast Asian aquaculture market, we recommend the ASTM standard 45mil geomembrane to our customers. It is an effective waterproof material and is widely used in the aquaculture industry. The customer provided the size and depth of the fish pond commonly used locally in Thailand. We use this to recommend the appropriate roll size based on the fish pond size. Because it is the first time for BPM to cooperate with a Thai customer, the customer cannot fully trust the quality of our products. After many times of communication, the Thai customer wants us to prove the quality of our products to him through video conference next Monday. During the video conference, our HDPE plastic sheet for fish pond quality inspectors tested various indicators of the pond liner, and the test results fully met the customer’s requirements. In addition, we introduced the complete process from raw materials to production to loading in the video conference in detail, and the customer very much agrees with this production mode. The customer recognized the expertise of BPM geomembrane after seeing our production process and tensile testing experiments.

After the meeting, BPM send the HDPE plastic sheet for fish pond samples and TRI test certificate to the customer as well as the case of our export geomembrane. The sample arrived in Thailand after a week, and the customer was satisfied with the quality of the sample. The yield tensile strength of HDPE geomembrane can reach 22KN/M, and the breaking strength is higher than 40kN/m. After we confirmed all the details about the order with the customer, the customer paid us a 30% deposit. Considering that the customer urgently needed these geomembranes for the project, we arranged the production as soon as possible, ensuring the quality and quantity and completing the production within three days. The customer received the geomembrane, and under the guidance of our engineers, all the installations were completed, Since then, it has maintained a mutually beneficial and win-win cooperation relationship with customers.

Benefits

High strength. The tensile strength at yield can reach 22kn/m, the tensile strength at break can reach 40kn/m, and the ductility is good. The elongation at yield is 13% to 16%, and the elongation at break is 700% to 800%. Has good surface compliance and weather resistance. When it reaches its peak, the strain is about 1000%. Especially for the pond floor and sides that need to bear the pressure alone, this physical property makes the pond more secure and durable.

Good anti-seepage ability. The anti-seepage coefficient is less than 1×10-13cm/s, which can ensure that the leachate will not pollute the land due to lining leakage, and the rainwater will not seep into the covering layer of the closed site, increasing the amount of leakage and leachate.
