Sludge pumps

The Double Disc™ pump from Penn Valley can be used for a variety of industrial sludge and slurry handling applications including but not limited to belt press feed, centrifuge feed, thickener feed, thickened sludge transfer, primary sludge, scum, septage, lime slurry, etc. Based on a Free Diaphragm™ technology, the pump uses an "induced flow" principle of operation whereby the discs perform the duties of both diaphragm and valve, providing a double acting, non-clogging pumping action. The elimination of check valves allows the pump to handle large solids, rags and fibrous material with no loss in pumping action.

Coagulants

GE Betz's all-organic tannin and starch technology can efficiently neutralize charges and coagulate solids, fats, oils and greases without producing excess sludge in a wide range of wastewater treatment applications. KlarAid™ coagulants are self-precipitating, with heavy metal complexing abilities and an affinity for oil and grease. They perform over a wide range of influent conditions and are safer and easier to use because of their all-organic structure derived from natural materials. Makedown and dilution is a simple process, and there is less need for pH or feedrate adjustments. The tannin and starch coagulants have minimal environmental impact, producing organic sludge that can be incinerated or landfilled.
