The right formula for Mogden

Posted: Monday 30th July 2012

Veolia Water Solutions & Technologies involved in major upgrade at Thames Water’s Mogden Sewage Treatment Works.

Veolia Water Solutions & Technologies will design and build an extension to the existing Sludge Pasteurisation Plant at Thames Water’s Mogden Sewage Treatment Works. The work is part of a major upgrade that will see Mogden’s process capacity increased by 50%. The increased throughput means more sludge production at the works, and this will be digested to produce biogas fuel which will meet the GLA’s target of 20% energy for the entire works from a renewable source.

The works extension is required to limit the quantity of partially-treated storm water discharged following heavy rain by increasing the works capacity of 1,064Ml/day flow to full treatment and to meet a revised consent. The resulting increased flow to treatment will result in a higher sludge load to the Pasteurisation Plant and then to the Digesters; the Pasteurisation Plant being a process adopted to kill pathogens before the digested sludge is taken off site for disposal.

To provide the additional pasteurisation capacity needed, Principal Contractor Black & Veatch selected Veolia Water Solutions & Technologies whose experience in the field is unrivalled. Each of the four new pasteurisation streams will comprise thickened sludge transfer pumps, a pasteurisation reactor, a heat exchanger, reactor blowers and pasteurised sludge transfer pumps. Each stream of the new plant will be controlled by a local control panel which will interface with the Mogden SCADA system. Site construction started in September 2011 and is scheduled for completion by January 2013.
