Large plastic pond liner Philippines, also known as pond liner material Philippines, used for biogas methane project is often the kind of HDPE geomembrane pond liner. The large plastic pond liner  is one of the most durable waterproof geosynthetic products, it is also widely used in sea water, freshwater fish and shrimp, mining engineering, garden engineering and salt ponds. BPM HDPE geomembrane liner uses fully automated production equipment and is produced through a three-layer co-extrusion blow molding process. Among them, the addition of its carbon black, anti-aging agent and stabilizer raw materials makes it have high resistance to stress cracking, puncture resistance and UV resistance.

2 Why Chose Large Plastic Pond Liner Philippines for Biogas Methane Power Project

The city in the Philippines where our customer is located generates approximately 100 tons of mixed municipal waste annually. If these wastes are simply buried on-site, they can lead to soil pollution, and the presence of organic matter in the waste further hampers effective resource utilization. Based on our discussions with the customer, we learned about their intention to harness the methane produced from biogas to power their factory. They expressed their desire to establish a comprehensive project and eventually integrate the generator set into the national grid. In light of these requirements, we recommend the use of 1.5mm large pond liners for this venture. These liners will serve as an ideal solution to address the environmental concerns associated with waste disposal while enabling the effective utilization of biogas resources for the customer’s factory.

3 Solution of Large Plastic Liner Philippines for Biogas Power Project

According to the customer’s requirements, this is a typical methane power generation project, the customer’s local voltage is 220V, in the initial stage, 20kva power is required, and the daily power generation time is 16 hours. Through simulation data and previous project analysis, it is concluded that 100 tons of municipal waste treatment requires 9800 square meters of 1.5mm large plastic pond liner, which will produce 25 cubic meters of methane gas every day, and the inlet air pressure is 20 psi. When entering the national grid to only supply power to the factory, an open-type single-phase 20kva gas engine is required. We considered that it is the first time for the customer to treat urban mixed waste with geomembrane, and the operation is unskilled, our professional engineers will guide it and give the following instructions.

  • The depth of the pool is large;
  • The bottom is flat, if the ground is not level, a layer of non-woven fabric can be spread;
  • Pipes should be added before the paving;
  • The slope is required to be 45 degrees, which is not easy to collapse;
  • The slope is designed to be as gentle as possible. Mouth to prevent explosion. Open flames are prohibited around the biogas digester, otherwise the leaked biogas may explode.The structure of the biogas digester.

4 The Structure of Biogas Digester for Large Pond Liners Philippines

  • The inlet pipe is designed at distance of 2m or 1m from the pool surface, the inlet and outlet pipes are at diagonal positions;
  • Drain pipe is away from the water surface. It depends on the required water level, and it cannot be exceeding the position of the air intake pipe;
  • Air intake pipe is about 1m from the pool, it is usually placed around the pool one week;
  • The slag discharge pipe at the bottom of the tank is placed horizontally at the bottom of the tank, and it will be set in the shape of a “well”, which is equivalent to an observation port. The water must be pressed against the mouth of the pipe. The more slag discharge pipes at the bottom, the faster the discharge. Block the slag discharge port when not discharging slag. Extrusion welding torch should be used to repair the leakage of the slag discharge pipe.
  • The general depth width and height of the anchoring ditch are 50-100cm. An anchor trench is approximately 70cm wide and 1 meter deep must be dug around the bottom of the biogas digester. The cover should be pressed deep, and the compacted biogas digester should be repaired later. You cannot use a hot-air torch, but a squeeze torch.

5 Benefits of Geomembrane Pond Liner Philippines for Biogas Methane Power Project

The construction of the biogas digester is convenient and quick to build using BPM large plastic pond liner. It takes at least 20 days to build a 20 square meters biogas digester with cement, while it only takes 20 days to build a 4500 square meters biogas digester with HDPE geomembrane pond liner, and the cost of the large plastic pond liner is low and energy efficient. Compared with the traditional biogas digester, it saves 60% of the cost; the fermentation effect is good. The HDPE geomembrane large plastic pond liner itself is black, which can effectively absorb the heat of the sun and increase the temperature of the pond, and is beneficial to the fermentation. To fully utilize the mixed garbage in the city, so that the resources can be effectively used. The methane in the biogas is burned to power the city reducing the cost of plant operation. The BPM HDPE geomembrane liner has good stability, strong acid and alkali resistance and aging resistance. It can reach a service life of 5 years in the case of sun exposure. At the same time, it has high anti-seepage coefficient and high tensile strength. It is used for storing biogas. Provide the necessary conditions for this project.

6 Summary

HDPE geomembrane large plastic pond liner for biogas methane power generation projects is main application area. Due to the low cost and short construction period, the benefits of this anti seepage lining and cover project are higher than traditional biogas digesters, especially in the Philippines, Mexico, Malaysia and other countries. Due to the favor of customers, BPM is committed to geosynthetics material research and development, we are trying our best to bring customers a better experience. Selling HDPE geomembrane liner is not our only purpose. We aim to provide customers with excellent services.
