Bluewater Bio secures contract for FilterClear technology from Severn Trent Water


Bluewater Bio Limited, a provider of treatment solutions to the water industry, has announced that  Severn Trent Water, through its capital delivery partner Mott MacDonald Bentley (MMB), has chosen Bluewater's high rate multi-media filtration technology, FilterClear.

This filtration technology is intended for tertiary solids removal plant at Codsall STW, Staffordshire.

BwB is offering a completely automated 4v2040 tertiary solids removal plant capable of treating up to 100 L/s of flow, to enable the site to meet the new consent of 0.5 mg/l for phosphorus, under the Water Framework Directive.

BWB commercial director Fergus Rooksby said: “This award allows us to showcase FilterClear as an ideal option for a chemical dosing approach to low phosphate concentration consents.

“We are seeing increasingly stringent discharge consents coming into force across the UK in AMP 6, with many water companies needing to implement enhanced P removal across numerous sites.

“Its modularity and excellent DfMA credentials make it an attractive solution to both tier one and end users. We believe FilterClear is well placed to capture a significant proportion of these schemes.”

FilterClear has been developed as a modular and scalable process which can treat flows ranging from 2 litres to 1,000 litres.

FilterClear emerged as the lowest total expenditure offering solution after being evaluated with other competing technologies.

Usage of FilterClear enables MMB to realise significant cost savings as a result of utilising the vessel headspace for flocculation, thereby removing the need to provide additional upstream flocculation with mechanical mixing.

Further, the relatively low head loss offered operational cost savings against higher head systems. The low operator intervention needs of a sealed filtration system further augmented the solution’s attractiveness for the Severn Trent operations team.

Its sealed filtration system minimises requirement for operator intervention.
