Practically indestructible, the Gravity Flow Systems Southwest, Inc. high-strength polyurethane media provides all of the process advantages of our stainless steel Wedgewater Filter beds in a very economical, corrosion-proof sludge dewatering bed. Fast sludge dewatering in a limited space, ease of use and maintenance, and a modular design lets you put them where you need them, as you need them.
Flocculated solids are placed on top of a bed containing the Wedgewater media. Typical water and wastewater treatment plant sludges can be dewatered to a liftable, truckable state in only a few days, compared to weeks or months with the normal sand drying beds. The system provides high capture rates and extremely clean filtrate. Dried solids removal can be accomplished using a small front-end loader. Once the cake solids have been removed, the bed can be washed down with a hose and is ready to go again.
