High density polyethylene liner is the impermeable synthetic HDPE geomembrane used for geotechnical engineering projects  so as to control fluid or gas migration or seepage in the human-made project such as canal, aquaculture, irrigation ponds and remediation liners and other lining applications include landfills, waste water treatment lagoons, oil and gas exploration and power plants, etc.

In biogas pond facilities, the prevalent choice for polyethylene liners is a formulation comprising high-density polyethylene blended with carbon black, anti-aging agents, anti-oxygen agents, UV absorbers, stabilizers, and other auxiliary materials. At this particular facility, the BPM polyethylene liner has been installed, featuring smooth surfaces that contribute to a notable reduction in interface shear resistance.

The use of high-density polyethylene, along with the incorporation of additives and stabilizers, ensures the liner’s durability and resistance to environmental factors. The presence of carbon black helps enhance the liner’s UV resistance, preventing degradation caused by prolonged exposure to sunlight. Anti-aging and anti-oxygen agents further contribute to the liner’s longevity and ability to withstand the challenging conditions within biogas pond facilities.

With its smooth surfaces, the BPM polyethylene liner facilitates efficient installation, providing a seamless and secure barrier against seepage. The reduced interface shear resistance helps maintain the liner’s integrity, preventing potential issues such as leaks or material displacement.

The selection of a reliable and well-designed polyethylene liner, such as BPM’s product, ensures the effective containment of biogas and the protection of surrounding soil and groundwater from potential contamination. The smooth surface characteristics and low interface shear resistance of the BPM polyethylene liner make it a suitable choice for the specific requirements of biogas pond facilities.

Why Chose High Density Polyethylene Liner for Biogas Pond Project

Biogas is usually made of organic manure waste from animals by anaerobic digestion treatment. So biogas is a kind of clean fuel, which can be used for household gas or cooking, water heating, etc. It can also generate electricity directly from gas. The biogas produced after fermentation is a clean fertilizer that can be used in organic agricultural fertilizers. The HDPE liner is one of the materials used to build biogas pond. The biogas pool adopts the anti-seepage membrane waterproofing method. Compared with the traditional reinforced concrete self-waterproofing method, the polyethylene liner biogas pond has many advantages such as long retention period of sewage, large amount of biogas production and low operating cost. Impermeable liner has natural superiority in terms of its construction cost, easy to maintain and management, gas production, power generation, sewage treatment and so on, so it has strong economic, social and ecological benefits.

High Density Polyethylene Liner for Biogas Pond Project in Dezhou

In 2016, BPM took on a medium-sized project involving an impermeable biogas polyethylene liner at Lia Ranch in Dezhou, Shandong province, China. The Construction Department of Shandong Province mandated that the biogas pond must meet specified requirements in terms of impermeability and volume. Our company served as the supplier for the Dezhou Lia Ranch Biogas Pond Project, actively participating in various aspects such as project planning, design, and installation.

The biogas polyethylene liner used in this project consisted of two main components: the substrate and the mask. The substrate acted as a barrier at the bottom of the biogas pond liner to prevent seepage, while the mask served as a sealant for the liner.

After extensive exchanges and on-site assessments, both parties agreed to use BPM’s 1.0mm-size polyethylene liner as the substrate layer and BPM’s 1.5mm-size impermeable liner as the mask layer for the biogas pond. This decision was made in accordance with the project requirements and specifications.

With over a decade of experience in constructing impermeable biogas ponds, BPM successfully completed the project under the guidance of Engineer Zhang. On October 9, 2016, the project underwent a comprehensive check and was accepted without any issues. The biogas pond system has since been officially put into operation, marking the successful completion of the project.
