Project introduction：

This is a very good example project of a low cost but effective digestion of straw and manure.  Cow manure is collected into the biogas plant by automatic scraper and back-flushing from the cowshed with solid digested residue bedding. This bedding made of digested dry manure saves the cost and avoids the adverse effect of sand on fermentation unit. The fertilizer intended to be used in a sustainable circle for the cow´s feedstock. But due to wrong policy it has to be treated in an expensive waste water plant. Killing the profitability of the whole project for our client. The biogas is utilized feeding 2MW/h into the electrical grid. We build four 4700m3 CSTR tanks, and use the submersible agitation and 40℃ mesophilic digestion technology.
