activated sludge pump

Sludge Pumps McMaster-Carr

These pumps provide about 25% more flow than standard float-switch activated pumps for sewage water. The float switch has a separate cord that can unplug, so you can replace the switch without replacing the whole pump. Pumps are equipped with a large intake and rugged impeller to transfer raw sewage water with solids up to 2" in diameter.

Introduction To Activated Sludge Study Guide

Activated sludge is a biological process that utilizes microorganisms to convert organic and certain inorganic matter from wastewater into cell mass. The activated sludge is then separated from the liquid by clarification. The settled sludge is either returned (RAS) or wasted (WAS). Activated sludge is commonly used as a wastewater treatment
