Bollfilter signs framework agreement with Anglian Water for planned maintenance

Posted: Tuesday 7th June 2011

Anglian Water is the largest water company in the UK by geographical area serving over six million domestic and business customers in the East of England and Hartlepool and supplying over one billion litres of water every day.

Much of the region is arable land and, as a result, certain potable water treatment plants in the area require nitrate removal. Nitrate Removal Plants (NRP) are high value capital equipment requiring pre-filtration to protect the internals from risk of contamination and Bollfilter automatic filters have been installed on twelve such Anglian Water sites.

The Filters typically provide filtration to 150 microns, with a set backflush once an hour. Automatic alarms are activated should the differential pressure rise above agreed levels.

Anglian Water has recently signed a Framework Agreement with Bollfilter UK to provide a three year maintenance and repair contract for all of the Boll NRP Protection Systems.

Although the Filters are designed for long-life operation with minimal maintenance, the Framework agreement covers regular annual servicing and repairs at a special negotiated fixed rate – extending the service warranty over the contract period.

Matt Rayson, Anglian Water Site Engineer, was instrumental in setting up the Franework Agreement. “Although we had few problems with the Boll Filters, they had been installed for several years without regular servicing. As most of our water treatment sites are unmanned, it is vital that our systems run without problems and this Agreement will give us peace of mind. Now, if we have any problems or queries with the water filtration, we can speak to someone over the phone or arrange an immediate site visit.”
