Scottish Water Cumnock

Scottish Water continues to prove its commitment to innovation and resilience with investment in CDEnviro S:MAX G at Cumnock.

Cumnock WwTW- part of Scottish Water who as a whole treat over 864 megalitres of wastewater every day to the people of Scotland- is located in Ayrshire. Although often seen as an old town with a Victorian feel, the treatment works at Cumnock is certainly not averse to innovation and continuous improvement.

Scottish Water Cumnock began trialling the S:MAX G screening technology back in September 2017 and then invested in the system in October 2018 after a successful trial.

The S:MAX G will be used to screen indigenous and imported sludges to recover rag and grit before the sludge is fed to gravity belt thickeners, anaerobic digestion and dewatering decanters on site. By removing rag and grit, Cumnock will not only protect downstream processes from wear and abrasion but also dramatically improve digester effectiveness. Grit that would have previously built up in the digester and required tank shutdown and cleanouts, is now removed beforehand, resulting in optimised uptime and efficiency. 

It is estimated that the system will save the Cumnock site significantly on digester cleanouts and pump wear costs alone.

Bill Gracie, Team Leader from Scottish Water Cumnock said, “The S:MAX G is a really useful piece of kit that’s helping us ensure reliable import screening and maximum digester uptime, which means we can process sludge more efficiently.  Our investment in the S:MAX G is just one way we are showing our commitment to innovation and resilience to create better value for our customers.”
