In our latest newsletter we announce the launch of our financing packages for our Odour Control solutions
What’s the problem?
Provide a system to remove odours produced by the newly constructed Surplus Activated Sludge Thickening System at Mogden Sewage Treatment Works.
How did you approach the challenge?
OSIL designed and manufactured a CuCarb® Odour Control System including fans, ductwork, exhaust stack, local control panel, instrumentation along with connecting ductwork and supports to 6 (Six) gravity belt thickener machines inside the new SAS building.
The challenge was designing a simple system that could overcome the difficult space requirements within the SAS building.
Delivering the Solution
Whilst the installation of the Odour Control Unit was straightforward due to OSIL’s vast experience in this area, installation of the internal ducting proved more of a challenge as ducting had to be installed above installed tanks at a high level with limited space to manoeuvre. The solution was to erect mobile access towers/ladder system to allow easy and safe access. OSIL sought the expertise of GAP Hire Group who undertook a site survey with OSIL to determine a safe & practical solution for access to the odour control connection points on top of the Gravity Belt Thickeners.
Whitlingham SBT, Odour Abatement System: LavaRok® Biofilter, CuCarbs®, Fans, Ductwork & Covers
Odour abatement of H2 S and ammonia extracted from covered tanks through an OSIL LavaRok® Biofilter followed by dual CuCarb® activated carbon polishing units capable of a 99% removal of 30ppm NH3 and 100ppm H2 S from a 12,500mÑ/h air stream. Final effluent water is continually sprayed over the graded LavaRok® pebbles to provide the correct environment for the inoculum.
The porous nature of the LavaRok® provides a large surface area for the inoculum to react with the odorous air. The CuCarb® units polish any odour not removed by the Biofilter. The benefit of CuCarb® over other carbons is the ability to continue the polishing process in a damp environment.
“While OSIL presented three options to help us prevent nuisance odours being produced, together with the relative capital and running costs, their LavaRok® bio-filtration system was clearly the way forward. Bio-filtration fits with our business ethics, from the unique long life media to employing natural biological processes.”

Keighley Brewery – Odour Control Plant
OSIL were invited to design, supply and install an odour control plant to capture and treat the odours from Timothy Taylor’s new effluent plant. The system was designed to extract 1,550m³/h from the sludge thickening building and comprises a range of interconnecting ducting, an extraction fan and a CuCarb® activated carbon unit with an H2S removal efficiency in excess of 99%. To ensure quiet operation the fan is housed within an acoustic enclosure.

“After analysing our emissions to atmosphere from our new effluent treatment plant we sought a company that could ensure we met exacting standards of odour reduction consistently and cost effectively. OSIL offered us a cost effective practical solution with a high level of industry expertise, design capability and customer service. It continues to work reliably and cost effectively and importantly helps us to meet the high environmental standards set by the company.”
