How Chemistry And Mechanics Deliver Cost-Effective Waste TreatmentSource: IPEC
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 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.
The collaboration resulted in a cost-effective sludge thickening system that operates in just one 8-hour shift. "It runs so well and is so user friendly that an operator can start the system and leave when his shift ends at 3:30 p.m., and the system shuts itself off at 6:00 p.m. that evening," said Ed Malcomnson, supervisor of wastewater systems for the City of Brockville.
