<p>Organic waste substances from animal farms, agriculture and food industry, are turned into methane gas and a deodorised high-nitrogen fertiliser in a fermenting vat. Its shape is open cylinder with a floating gas bell or a spherical container, made of suitable material, pref. plastic. Its walls contain all pipes for the inlet and outlet and for a circulation of the contents of a pump jet. This system combines a high gas yield and low operating costs with low capital costs and a long service life of the vat.</p> |
