Dŵr Cymru Welsh Water committed to Discfilter Technology

Veolia Water Solutions & Technologies is to supply another Hydrotech® Discfilter tertiary treatment plant to Dŵr Cymru Welsh Water.

This new contract, which follows similar installations at a number of other Dŵr Cymru Welsh Water wastewater treatment works, will see two Hydrotech HSF2212/11-1F Discfilter units being installed at Connahs Quay WwTw as part of a £1.65m upgrade being carried out by Imtech Water, Waste and Energy, one of Dŵr Cymru Welsh Water's AMP5 partners. The upgrade, due for completion in July 2013, will accommodate growth and improve final effluent quality at the 20,000 population equivalent works.

Each of the Discfilters will treat 113l/s of final effluent to a suspended solids standard of 15mg/l 95%ile. The contract includes design, supply, and installation of the two filters, which will be fabricated in 316 stainless steel and Glass-reinforced Plastic (GRP) and fitted with advanced self cleaning backwash spray nozzles. The advanced nozzles will provide further operational robustness and reduce operator intervention.

The Hydrotech® Discfilter uses a series of rotating segmented discs that support 10 micron polyester filter fabric panels. As the wastewater flows through the disc segment, suspended solids including biomass flocs and precipitated phosphates are captured on the fabric and removed from the effluent. When required, backwashing of the fabric is initiated automatically on headloss, with the dirty backwash water being returned to the head of works. Low backwash water volumes, typically only 1 - 3% of throughput, low power consumption and minimum maintenance by comparison with competitive technologies make the Hydrotech® Discfilter not only cost effective but a more sustainable option.

In addition to installations in Thames Water, Scottish Water, Yorkshire Water, Anglian Water, Severn Trent and United Utilities, Hydrotech® Discfilters are also providing tertiary treatment at Dŵr Cymru Welsh Water's Churton, Farndon and Mold wastewater treatment works, treating 10, 14.6 and 92 l/s respectively.
