How Chemistry And Mechanics Deliver Cost-Effective Waste Treatment

Brockville, Ontario municipal waste treatment plant gains a flexible, cost-effective sludge thickening system.

Polymer chemistry is one of the leading considerations when designing a sludge thickening system. The right polymer chemistry contributes to more effective thickening at a lower cost. However, the right chemistry must also be complemented by mechanical processes that enable the chemistry to work effectively. Waste treatment equipment manufacturer JWC Environmental | IPEC collaborated with polymer suppliers for extensive lab trials to design a waste activated sludge (WAS) thickening system for the City of Brockville, a city of more than 23,000 people located in the southeastern part of Ontario, Canada. The rotary drum system is capable of thickening 5.25 I/second of 0.55 percent municipal sludge to up to 7 percent solids.
