Thames Water increases sludge handling and reduces odour

Thames Water increased sewage treatment capacity, improved operating efficiency and reduced odour at its Beckton, Mogden and Crossness sewage treatment works.

Situation

Thames Water needed to increase sewage treatment capacity, improve operating efficiency and reduce odour at its Beckton, Mogden and Crossness sewage treatment works.

Problem

Thames Water had a total of 53 primary settlement tanks at its three plants that each needed to address sludge and surface scum.

Solution

Hydro International provided Zickert™ Reciprocating Sludge Scrapers to remove sludge and scum from primary settlement tanks.

Outcome

The  Zickert™ Reciprocating Sludge Scrapers are helping Thames Water towards its target of 50% increased sewage treatment capacity at Mogden and 44% increased capacity at Crossness.

"Thames Water decided to use Zickert™ scrapers for primary treatment to replicate the good performance and reliability of the existing Zickert™ tanks installed at Beckton in 2007 and 2009. They recognised that the Zickert™ process was a good one for wider upgrade of the facility."
