Lamella Separator Systems: Heigham Water Treatment Works (WTW)

World leading energy provider GE Power and Water (SUEZ) awarded Colloide the contract to supply a Lamella Settler System for Heigham Water Treatment Works in Norwich. This project was completed in May 2018 on time and to the original agreed value.



Scope of work

The scope of works included a 3-stream system, an integrated platform with access to stairs, flocculation tank and splitter tank.

This 3-stream system was installed to handle a peak flow of 9,800m3/day. Colloide included a flow splitter chamber to split the flows evenly to 4 streams (1 future stream) and pipework from between this tank and the clarifiers.

Covers were installed on the flocculation and clarifier tanks which also act as walkways over the complete area. Colloide have included a system to drain surface water off the tanks which is then returned to the treatment process.

This project included a full set of stainless steel lamella settlers which are certified to DWI standards. These are mounted within stainless steel tanks with flocculation tanks upstream of these settlers. Sludge is collected under the lamella settlers and concentrated up to 3% DrySolids.
