Trident’s sludge dewatering press MD Press 454 is featured in the August issue of the Treatment Plant Operator Magazine. The MD Press 454 dewatering press can process up to 250,000 gpd with about 4,000 lbs DS/hr. It features four dewatering cylinders, each powered by a 1.5 kW motor. The cylinders are strategically designed to allow efficient thickening and dewatering in a single operation. The maintenance requirements are drastically reduced due to its self-cleaning design. The equipment can accept highly dilute sludge and, depending on the requirements, produce high solids cake with up to 20-30% dry matter. The press operates fully automated, requiring little operator attendance and simple maintenance procedures. It is available with an optional flocculation tank and mixer unit.
