Digester

Issue

Poultry breeding pollution is becoming the third largest source of pollution after industrial pollution and domestic waste pollution. In some areas, the discharge of pollutants from the livestock and poultry breeding industry has become one of the important causes of water pollution and eutrophication. Waste from livestock and poultry breeding has seriously affected the sustainable development of animal husbandry. In recent years, there has been a shortage of workers in farms. Many farms have transformed the manure removal process into a “blister manure” process, which mixed livestock and poultry manure, resulting in serious overloading of sewage treatment projects built in previous years.

Solution

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.

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.

Benefits

1. The biogas digester HDPE geomembrane saves sewage treatment fees. Manure is processed through biological composting and anaerobic fermentation to reduce human and animal diseases.

2. The HDPE anti seepage geo membranes reduce other harmful impurities in sewage, and prevent the pollution of the downstream water quality of groundwater, and protect the physical and mental health of the local downstream drinking water population.

3. Biogas digester HDPE geo membranes break through the construction materials of traditional biogas digesters. The HDPE geomembrane uses impermeable geomembrane materials, which can effectively replace conventional construction materials at low cost to solve the problems of shortage of construction materials and high prices. Generally, black biogas digester geomembrane is the good choice.

Summary

HDPE Geomembrane is a kind of waterproof barrier material based on high polymer. HDPE geomembrane is made of high-quality virgin resin, the main component is 97.5% high density, about 2.5% carbon black, anti-aging agent, antioxidant, ultraviolet absorber, stabilizer and other auxiliary materials. It has good resistance to environmental stress cracking and chemical corrosion resistance; good chemical corrosion resistance; has a large operating temperature range and a long service life, and is widely used in biogas digesters, tailings storage sites, and channel seepage prevention , Dam seepage prevention subway project, etc.
