Severn Trent Water is saving a total of £100,000 per year on energy and maintenance costs across a number of its wastewater treatment plants following the installation of award winning technology from ABB and its Drives Alliance member, Inverter Drive Systems (IDS).
Developed by IDS and known as reactive pump control, the new method of controlling sludge in sewage treatment plants uses an ABB low voltage AC drive, combined with a specially written software algorithm to measure viscosity and achieve the flow control demanded by the sludge pumps.
The system was trialled at Severn Trent’s sewage treatment site at Pye Bridge. It reduced pumping time by 90 percent by running the pump on average for 10 minutes per five hours, saving £42,000 a year.
A number of other installations are now operational at Rainworth, Boughton, and Calverton. Overall, savings in energy and maintenance hours across the sites have totalled £100,000 a year.
