Currently, China's environmental sanitation is becoming stricter. As emissions are below the standard, more and more farms are closed. Due to the economics of the retail industry, the construction of black film biogas digesters is a basic requirement for farm environmental impact assessment. Its strength cannot be compared with that of large aquaculture enterprises. Therefore, the construction of black film biogas is one of the most cost-effective methods. The black low cost textured geomembrane used in the black membrane biogas digester is also called impermeable membrane and waterproof board. Advantages of using biogas digester geomembrane The following is my summary of the advantages of using LDPE geomembrane manufacturers in biogas digesters: 1. The black film biogas digester is cost-effective and the best choice for some small free-range families. It can meet environmental protection requirements with minimal investment, and can also produce biogas for power generation and save energy. 2. The black film biogas digester has a long service life. Compared with some early cement biogas digesters, the black membrane biogas digesters have a long service life and a biogas digester waterproof board made of double resistors (anti-ultraviolet and anti-oxidation) has a normal service life of over 10 years. 3. The black membrane biogas adopts waterproof board to prevent seepage effect. The surface temperature of the black waterproof board can reach 60 degrees in the sun, which can greatly increase gas production and shorten the fermentation time.
