OSIL have recently installed two odour control systems for May Gurney at Anglian Water’s Whitlingham STW

Posted: Thursday 15th September 2011

The system serving the clamp press enclosures treats 100ppm ammonia and 40ppm hydrogen sulphide from a 6,500m3/hr air stream and incorporates dual ChemKlean® scrubbing columns designed to achieve 99% removal efficiency. Each scrubber continually re-circulates the scrubbing liquor over a packing media and the strength of the reagents in the liquor is automatically controlled by a chemical dosing system.

The odour control system serving the SBT tanks comprises of a LavaRok® biofilter followed by dual CuCarb® activated carbon polishing filters and is achieving at least 99% recovery of 30ppm ammonia and 100ppm hydrogen sulphide from a 12,500m3/hr air stream. Final effluent water is continually sprayed over the graded LavaRok® media to ensure the correct environment for the inoculum.

Both turnkey systems were supplied complete with ducting, extract fans, electrical controls and instrumentation and completed to time within a 26 week period.
