Ferric sludge
Drinking water sludge treatment – trial
August 2010
Sludeg Treatment Reed Bed
The asset management strategy for Essex and Suffolk Water identified a need for a new process for sludge handling at Hanningfield Water Treatment Works (WTW). Supplied with raw water from Hanningfield Reservoir (354 Ha), Hanningfield WTW produces 150 million litres of potable water a day. As part of the water treatment process, 2-4 million litres of ferric (Iron) sludge per day is generated primarily from the de-sludging of the Pulsator clarifiers. The sludge is primarily a mineral sludge with seasonally fluctuating levels of algae and suspended solids.
