[Case Study] GREER COMMISSION OF PUBLIC WORKS (CPW)Polyblend® system reduced polymer by 47% while maintaining the same or better dewatering performance

Greer Commission of Public Works (CPW) has been providing water, wastewater and electric services to the City since 1914 with natural gas service added in 1957. CPW has been treating wastewater at the Maple Creek WWTF since 1955 and has subsequently won many awards (most recently, the National Association of Clean Water Agencies Peak Performance Gold Award). The Maple Creek plant is anchored by a 5 MGD Activated Sludge and Sequencing Batch Reactor with 2 MGD average flow that provides treatment for 12,000 connections in the Greer area.

Ever vigilant for improvement ideas, Ronnie Turner, the plant operations manager attended “The Science of Polymer Activation” seminar by Dr. Yong Kim of Cleanwater1, formerly UGSI Solutions at the South Carolina Environmental Conference in order to learn more about optimizing polymer use in his dewatering process. Afterward, Ronnie visited the Cleanwater1 formerly UGSI tradeshow booth to hear more about the unique two- stage tapered energy mixing profile of the Polyblend® polymer activation system which improves polymer dewatering efficiency.
