Anaerobic Digestion Mixing Products

High efficiency mixing for anaerobic digestion

Trends in anaerobic digestion aim to reduce retention time and increase dry solids concentrations, raising organic loading and improve efficiency. With increased organic loading of digesters, mixing becomes critical to ensure the whole digester volume is available for processing; fresh feed material is mixed uniformly within the reactor; and the biological breakdown products of digestion are dispersed
