3 Why Chose BPM HDPE Geo Membranes Zambia for Biogas digester Projects

Choosing BPM HDPE Geo Membranes in Zambia for biogas digester projects offers significant benefits. Poultry breeding pollution is a major concern, ranking as the third-largest source of pollution. The discharge of pollutants from the livestock and poultry breeding industry contributes to water pollution and eutrophication, negatively impacting the sustainable development of animal husbandry.

To address these challenges, many farms have adopted the “blister manure” process, which mixes livestock and poultry manure. However, this has led to the overloading of existing sewage treatment projects, necessitating effective solutions.

BPM HDPE Geo Membranes provide an ideal choice for biogas digester projects. These membranes act as a barrier, preventing the leakage of pollutants into the environment. They can efficiently manage mixed manure, ensuring the proper treatment and containment of waste. With their longevity, durability, and resistance to chemicals and UV radiation, BPM HDPE Geo Membranes are well-suited for the demanding conditions of biogas digester projects, contributing to pollution control and sustainable agricultural practices.

4 Solution of BPM HDPE Geomembranes Zambia for Biogas digester Projects

Smooth HDPE Geomembrane is the low permeable synthetic membrane liner and geotechnical engineering materials which are widely used for solid waste containment, mining and water containment applications. BPM smooth HDPE Geomembrane is made of finest quality high density polyethylene (HDPE) with specially formulated, virgin polyethylene resin, combined with specified quantity carbon black, antioxidant, anti-aging agent and UV resistance components, which makes our smooth HDPE Geomembrane with excellent resistance to UV radiation and is suitable for exposed conditions.

Nowadays, the use of anaerobic digester is a good option for renewable energy and the replacement of fossil fuels. The HDPE geo membranes as anti seepage lining materials play very important role in the biogas digester projects for their characteristics of anti-aging, acid and alkali resistant and rodent resistance. The HDPE waterproof geomembrane biogas digester has the advantages of large anaerobic fermentation volume, long wastewater retention period, large biogas production, and low operation and treatment costs. It is very suitable for the treatment of large-scale farms and “blister manure” craft farms. There are many benefits of constructing a waterproof geomembrane biogas digester. The intuitive thing is that the “belly volume” is large, and the amount of waste liquid and biogas that can be stored is 10 to 20 times more than that of a conventional biogas digester. It has natural advantages in terms of construction cost, maintenance management, gas production, power generation, sewage treatment, etc., and therefore has strong economic, social and ecological benefits. The biogas digester geomembrane project can also save fertilizer costs.

The biogas digester HDPE geo membranes integrate fermentation and gas storage. The HDPE geomembranes are used to completely seal the entire anaerobic ponds. The HDPE geomembrane liner has simple and convenient construction, low cost, simple process flow, convenient operation and maintenance, long sewage retention time, sufficient digestion, and sealing Good performance, large daily production of biogas, high tensile strength of the anti-seepage membrane material, strong anti-aging and corrosion resistance, good anti-seepage effect, use of biogas to generate waste heat, film to absorb sunlight, heat preservation effect, and automatic drain at the bottom of the pool. The advantages of sludge device, less sludge in the pond, etc.

At the same time, the biogas digester HDPE geo membranes can also solve the problems of water seepage, water leakage, and air leakage caused by the shrinkage and expansion of concrete biogas projects due to temperature changes, and the steel plates of the ground-type steel plate biogas projects are easy to corrode, pipelines are easy to block, and equipment is easy. Problems such as damage and high operating costs.

BPM customer in Zambia found us from our company’s website, and the customer wanted to build a biogas digester to solve the pollution caused by animal breeding. We recommend the use of high-standard ASTM standard HDPE geo membranes, which has high tensile strength, strong corrosion resistance and good anti-seepage effect. It is the main material for biogas digesters and sedimentation tanks in farms, and can well solve customer problems. Because the top film of the biogas digester HDPE geomembrane is exposed to the outside for a long time, it is easy to be aging due to wind and sun, so you should choose the ASTM standard HDPE geomembranes with better aging resistance. It is recommended to choose 2mm thickness. This kind of geomembrane is produced by blown film technology. The indicators such as strong are far better than the black film produced by ordinary laminating film. As for the bottom membrane, it is recommended to use 1.5mm ASTM standard HDPE geomembrane due to the sewage coverage and the protection of the top HDPE geo membranes.

5 Benefits of HDPE Geomembranes for Biogas digester Projects in Zambia

The use of HDPE geomembranes in biogas digester projects in Zambia offers several benefits:

  1. Cost Savings: HDPE geomembranes help save sewage treatment fees by facilitating the biological composting and anaerobic fermentation of manure. This reduces the reliance on external sewage treatment facilities, resulting in cost savings for the project.
  2. Pollution Prevention: The anti-seepage properties of HDPE geomembranes prevent the leakage of harmful impurities from the digester, protecting the downstream water quality of groundwater. This helps safeguard the health of the local population relying on downstream drinking water sources.
  3. Construction Efficiency: HDPE geomembranes provide a breakthrough in traditional biogas digester construction materials. By using impermeable geomembrane materials, the need for conventional construction materials is reduced. This not only lowers construction costs but also addresses issues of material scarcity and high prices.

The implementation of HDPE geomembranes in biogas digester projects in Zambia brings economic, environmental, and health benefits by reducing costs, preventing pollution, and improving construction efficiency.
