Wastewater treatment plants are trying to find ways to reuse their valuable sludge through anaerobic digestion, as well as lower their overall carbon footprint. The Monster Rotary Sludge Thickener brines sludge up to 15% solids, depending on the types of sludge; minimizes CAPEX and OPEX costs by thickening sludge prior to centrifuge dewatering; is a fully enclosed system that allows for odor control compared to gravity belt thickening; and provides fast flocculation, which leads to low polymer use and requires a relatively small mixing tank.
