Georgetown County finds new flocculator
The water utility for Georgetown County in South Carolina found that its replacement flocculators showed almost no settling or build-up in its basins after a year of operation.
The Georgetown County Water and Sewer District Public Water Utility (GCWSD) has adopted a new flocculator and is pleased with its results.
The GCWSD has been operating in South Carolina since 1967. It is responsible for supplying more than 20,000 households and established industrial and commercial enterprises. Among other things, GCWSD operates a drinking water treatment plant, which recently required replacement of aging equipment. These updates included a replacement of their vertical inclined-blade flocculators, which had reached the end of their useful life.
In their search for a high-performance replacement that could solve the problems associated with the accumulation of solids in the flocculation basin, while still maintaining good floc formation, the managers found what they were looking for through a local distributor, DXP Premier Water of Charlotte, N.C. They ultimately offered the INVENT HYPERCLASSIC® Flocculators.
The HYPERCLASSIC Flocculator utilizes a hyperboloid shape to effectively balance the amount of mixing energy required to prevent settling in the floc basins, while simultaneously minimizing floc shear. This hyperboloid shape allows for a gradual acceleration of the floc particles to gently transfer the mixing energy to the particles and prevent breakage.
After the first year of operation the plant staff inspected the new hyperboloid flocculators and found almost no settling or build-up in the flocculation basins, even when using lime for pH adjustment. This was a welcome change for maintenance staff from the previous equipment, which used to cause significant settling and sludge buildup.
