Temporary belt press provides relief
Problem
The dewatering equipment at the Grand Chute-Menasha West Wastewater Treatment Facility in Neenah, Wis., had to be offline during construction. Operators believed a 2-meter mobile belt press could process 150 gpm or more of autothermal thermophilic aerobic digested biosolids at 3.2 percent solids, but the unit was unavailable.
Solution
A demonstration of the 1.7-meter extended length (XL) mobile belt press from Bright Technologies proved the unit was adequate. Company representatives tested the biosolids before recommending a polymer, then suggested where to place the press for maximum efficiency and minimal labor.
