Evoqua Water Technologies has been selected by Severn Trent Water and its design and construction partner, Costain Ltd., to supply Evoqua's CoMag ballasted clarification system to reduce phosphorus at the Finham Sewage Treatment Works in Coventry. Finham will be Europe's first wastewater treatment plant with a permanent installation of Evoqua's ballasted settling technology, which has been proven in facilities throughout the United States for more than a decade. The CoMag system uses magnetite fully inert, iron ore particles to enhance the clarification process. The system settles chemical floc up to 30 times faster than conventional clarification. For communities that face challenging wastewater characteristics due to industrial discharge or dense populations, the CoMag system is the ideal solution. The tertiary CoMag system will help Severn Trent Water reduce both total suspended solids and phosphorus before the treated water discharges into the River Sowe. Algal blooms and poor river ecosystems are triggered by high levels of phosphorus in the river. To combat the blooms and restore water bodies to good status, the UK Environment Agency's National Environment Programme (NEP) is imposing low phosphorus limits on many wastewater treatment plants, including Finham. The CoMag system will significantly decrease the amount of phosphorus that the works discharges and will ensure compliance with the new phosphorus limit of 0.22 mg/l of total phosphorus (T-P).
