SUEZ Water Technologies and Solutions products

Designed to recycle biosolids into methane and valuable byproducts, SUEZ’s advanced anaerobic digestion technologies use bacteria in the absence of oxygen to break down matter to create biogas. The biogas can be combusted or oxidized and used for heating or with a CHP engine to produce electricity and heat; it can also be compressed and used as fuel for vehicles with the cake produced, used as a fertilizer.

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
