Bluewater Bio awarded Phosphorus Removal Contract by Severn Trent Water

Bluewater Bio Limited, a leading provider of treatment solutions to the water industry, is pleased to announce that  Severn Trent Water (“Severn Trent”), through its key capital delivery partner Mott MacDonald Bentley (“MMB”), has selected the Company’s high rate multi-media filtration technology, FilterClear, for the provision of a tertiary solids removal plant at Codsall STW, Staffordshire. BwB are providing a fully 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.

After an extensive evaluation of competing technologies, it was concluded that FilterClear offered the lowest TOTEX solution. By using FilterClear MMB were able to realise significant cost savings as a result of utilising the vessel headspace for flocculation, thereby eliminating the need to provide additional upstream flocculation with mechanical mixing. Additionally, 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.

FilterClear is both a modular and scalable process, treating flows ranging from 2 L/s to in excess of 1,000 L/s.

Fergus Rooksby, Commercial Director of Bluewater Bio, commented: “We are delighted to work with both Severn Trent and MMB on this P removal scheme. 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.”

The contract with Severn Trent marks the Company’s second P removal scheme in the past 12 months, with FilterClear currently being assessed by Yorkshire Water, as part of the National Chemical Investigation Programme (CIP), at Bolsover STW.
