The new plant consists of anaerobic treatment of sludge and wastewater (BIOPAQ IC) combined with biological sulphide oxidation (SULFATEQ) and the Paques' process for nitrogen removal (ANAMMOX). COD, sulphate, sulphide, chromium and nitrogen are all removed to low levels. The amount of solid waste was significantly reduced compared to the earlier physical/chemical treatment. The biogas generated in the treatment process is used to produce electricity.
