Drive units
Clarifier and thickener drive units provide the rotational force necessary to turn the rake arms in a circular basin. The rotating rake arms transport settled solids to the center of the tank for removal. Because drive units are applied in water and wastewater treatment plants as well as industrial facilities, WesTech has developed a premium drive unit for each application. WesTech drive units can be designed for torque requirements from 1,000 ft-lbs to 6,000,000 ft-lbs. WesTech drive units are delivered to the job site as a single, completely assembled and shop-tested unit, ready to be installed on the thickener or clarifier center column.
