An adaptable, efficient solution for treating your high sediment waters.

The Culligan® OFSY models offer a fully automated treatment process optimized to provide filtration of feed waters, particularly surface waters with suspended solids and high turbidity levels. The commercial models include a clarifier and filter in-series to provide eight different layers of filtering minerals to capture impurities. OFSYs come standard with Culligan®'s smart controller to automate most flow control operations. Our design allows for easy integration of different chemical feed systems for pretreatment operations (coagulation, flocculation, and chlorination, etc.)
