Digester

WesTech Engineering ExtremeDuty sludge mixer

ExtremeDuty sludge mixers from WesTech Engineering are designed to combat rapid rise events that can cause millions of dollars in damage at plants, from sludge plugging the pressure relief valves and flame arrestors to tank and cover damage. Trapped gas within the sludge content builds up but has no way to get out. It can form a scum layer on top, stratified sludge layers, or varying pressures and temperatures throughout the digester. If the mixing is inadequate, the result can be stratified sludge, a scum layer, a large grit layer or higher liquid levels due to gas entrapment. The mixers provide high flow rates while pumping both upward and downward, providing needed floc shear in the tank. The change in flow also aids in preventing stratification, suspends grit and disturbs the top of the sludge to break up the scum layer. 801-265-1000; www.westech-inc.com
