SEPARATOR

The Separator is used for separation of digested biomass into solid and liquid fractions and is included into the basic equipment of the biogas plant. Separator components are made of corrosion- and abrasion-resistant steel. The digestate is either gravity fed or is fed to the loading chamber by means of pumps through a supply branch pipe. From the loading chamber digestate is fed to the separator by the use of a varied pitch auger made of abrasion-resistant steel. Separation chamber is a cylindrical sieve also made of abrasion-resistant steel. Liquid and solid fractions are separated by means of pressure and filtration in the separator. Liquid fraction is poured out through an emptying fixture secured to the accumulator tank. Solid fraction with the help of an unloader leaves the separator and is accumulated in a bin.
