Sulphate removal from starch processing water

A Dutch operation of starch processing company Cargill treats its sulphate-rich water with an anaerobic bioreactor. This produces biogas that is rich in hydrogen sulphide. Cargill chose THIOPAQ® technology to remove the hydrogen sulphide, which enables them to meet the legislation for sulphate discharges. Also, two of Cargill’s production sites in the USA apply THIOPAQ® biogas desulphurisation.
