Black film biogas digesters are increasingly favored by farmers due to their low cost, good performance, and high biogas production.

How much does it cost to build a pig farm biogas digester?

1. Black film biogas digester is a super large biogas digester that integrates fermentation and gas storage. Its manure treatment principle is similar to other anaerobic biological treatment processes, relying on the metabolic function of anaerobic bacteria to degrade organic substrates and partially convert them into biogas.

2. The black membrane biogas digester uses black anti-seepage geomembrane as the anti-seepage substrate, sealing the bottom and top into a super large anaerobic sewage reactor.

The anti-seepage geomembrane has the advantages of high and low temperature resistance, oil and tar resistance, acid and alkali salt resistance and other strong acid and alkali chemical medium corrosion, good anti-aging performance, strong ultraviolet resistance, anti decomposition ability, high anti-seepage coefficient, strong tensile resistance, exposed use, long service life, etc.

The principle and advantages of black film biogas digesters were introduced to you above. How much does it cost to build a biogas digester for a pig farm?

Here, I will share it with everyone. Firstly, let's take a look at the scale of the breeding farm, the current amount of breeding, and the close correlation between the breeding amount and the volume of constructing black film biogas digesters.

For example, if the current aquaculture capacity is 5000 heads, we need to build a 5000 cubic meter biogas digester and a 3000 cubic meter oxidation pond. If the breeding volume is 2000 heads, then the biogas tank is 2000 cubic meters and the oxidation pond is 1000 cubic meters. The same amount of breeding and the same volume of biogas digesters are sufficient.
