Dewatering

Charter Machine Company manufactures belt filter presses for reliable sludge dewatering across municipal wastewater treatment, industrial processing, and biosolids handling applications. These sludge dewatering systems provide consistent, high-throughput performance across a wide range of sludge types and feed conditions. Belt filter presses are available in multiple configurations, including horizontal and vertical designs, two- or three-belt systems, varying belt widths, and configurable gravity deck lengths to match specific process requirements and throughput demands. Systems can also be configured as mobile units or fully integrated, plug-and-play solutions incorporating feed pumps, compressors, polymer systems, mixers, conveyors, and control panels. Based on extensive operator feedback and field experience, these belt filter press systems achieve stable solids capture, consistent cake formation, and efficient water removal to produce higher dry solids content. For more information on the sludge dewatering process, see our detailed guide on belt filter press operation.

The Royal Screw Press achieves very high efficiency with a low power consumption due to the low-speed operation. The power range is from 0.75 kW to a maximum of 5.5 kW with flow rates up to 200 GPM while producing 25%+T.S.cake.

CMC Mobile Dewatering Units have long been the choice of many municipalities and industries. Their mobility offers flexibility and provides unique problem-solving capabilities.

Skid mounted systems are available in all sizes and models.

This economical, simple to operate and easy to maintain option effectively de-waters challenging municipal or industrial sludges, eliminating the need for drying beds or more costly alternatives.
