AC drives overhaul Severn Trent sewage treatment

摘要

A new upgrade service introduced by the ABB Drives Alliance led to the Severn Trent water utility achieving more than a 65% energy saving and a payback in only seven months following its replacement of three 37 kW AC drives on water process pumps. As a result, Severn Trent set up an Energy Saving Project group to look at replacing and upgrading existing drives, as well as installing new drives throughout its network of sewage treatment plants.
