Overhaul of Digester Mixing System Delivers Better Biogas Yields
It is hard to understand a design that doesn’t allow equipment to be looked after! The mixers couldn’t be lifted out of the tank for even the most basic of service tasks such as an oil change and cleaning the propellers. The secondary digester is now served with a system that comprises the proven Landia chopper pump, fitted with venturi nozzles to provide truly comprehensive mixing. When the primary digester meets the right level, the feedstock is automatically transferred to the secondary digester.
