SEEPEX Innovative Pump Solutions Power Sustainable Sludge Treatment at Thames Water

Thames Water owns and operates Basingstoke Sewage Treatment Works. This regional sludge treatment centre processes sludge in either liquid or cake form from various locations. The Basingstoke Sludge Treatment Centre (STC) houses advanced facilities, including thermal hydrolysis and anaerobic digestion plants, capable of processing 53tDS/day of sludge from Basingstoke, Farnham, Fleet, Guilford, and Newbury. The site now generates enough energy from waste to power itself and export to the national grid.

The pulper feed pumps from another supplier were experiencing stator failures every four months, which caused breaks in the processing of the sludge, leading to reduced energy production and time-consuming, costly repairs. Thames Water approached SEEPEX with the task to offer a more reliable pump, capable of efficiently transferring up to 30 m3/hr of 6-10%DS high-temperature sludge.

The SEEPEX BNM maintain-in-place pump range is designed to simplify maintenance for large and challenging-to-maintain pumps. By leveraging innovative design features, maintenance time is significantly reduced, up to 80%. Fast and straightforward maintenance of pump components ensures streamlined preventative inspections and improves operational reliability and service life, effectively eliminating unscheduled downtime.
