템스워터(Thames Water)의 하수 향상 프로젝트의 일환으로 처리 시 용량증가에 대응하는 Vaughan Chopper 펌프를 사업에 사용한다. 이번 사업은 2021년 10% 증가하는 예측 인구에 대비해 이스트런던(East London)의 Beckton 및 Crossness의 하수 용량을 증가시킨다. Beckton에는 1억9천만 유로의 투자가, Crossness에는 2억2천만 유로의 투자를 통해 44%로 처리 용량을 증가시킬 전망이다.
 
또한 템스워터는 대규모의 강우가 발생한 후의 과정에서 범람하는강우의 양을 축소시키는 목적을 가진다.

 

 

 

As part of Thames Water’s sewer upgrade project, the utility used Vaughan Chopper pumps to cope with increase capacity at the treatment works.

 

The utility is increasing sewer capacity at its Beckton and Crossness sites in East London to cope with a predicted population incase of 10% by 2021.

 

The projects, valued at ￡190 million for Beckton and ￡220 million for Crossness, will boost the site’s treatment capacity by 44%.

 

The aim is to also reduce the volume of storm sewage that often overflows into the Thames water course during and after heavy storm events.

 

A key part of both projects involves the extraction of biogas from the organic waste within the sewage processed at both sites.

 

Extraction of the gas is performed by 12 anaerobic digesters across the two sites and each digester uses a pair of Vaughan HE6W10-277 Horizontal Chopper Pumps driven by 30kw/4 pole WEG motors, selected and supplied by P&M Pumps.

 

The WEG motors include ATEX conforming EExd ratings.

 

Matt Harvey, director at P&M Pumps, said: “This application is extremely demanding as the load on the chopper pumps can be exacerbated by the substantial debris that can sometimes reach the pumps in spite of the upstream filters.”
