CMC's sludge thickening solutions can help minimize the volume of any liquid feedstock or waste stream. Thickening processes typically concentrate the dry solids content (DS) to a range of 4-12%. These systems use polymers to flocculate the sludge, allowing the separated water to drain by gravity. For even drier material, the thickened sludge can be further processed by downstream dewatering equipment.

Dewatering significantly reduces water content, transforming liquid sludge into a concentrated cake typically ranging from 15–30% dry solids (DS). This dewatered material is easier to handle, transport, and store compared to untreated sludge. By removing water beyond what thickening can achieve, dewatering improves operational efficiency and reduces costs associated with storage, processing, transport, and final disposal.

Take sludge treatment a step further with CMC's innovative sludge drying.  This second-stage process builds upon the work of mechanical dewatering machines like screw presses, belt presses, and centrifuges.  By using advanced methods like non-thermal electro-osmosis and low-temperature drying, CMC's energy-efficient drying equipment transforms dewatered sludge cake into a drier, more concentrated material with a remarkable dry solids (DS) content of 50-90%.

Charter's expertise extends beyond dewatering. We offer a comprehensive suite of material handling solutions, including custom-built belt and screw conveyors. These versatile conveyors can handle a wide range of materials, from sticky and lumpy semi-solids to coarse dry materials, ensuring efficient transport throughout your entire production cycle, even in harsh industrial environments.

Optimizing thickening and dewatering starts with the right polymer. These bridging agents bind suspended solids, promoting liquid separation. A truly effective polymer solution should be selected and aged properly to achieve its highest activation, resulting in the unfolding of the molecular chains. We offer a comprehensive line of polymer solutions, encompassing both dry and emulsion systems.  Our Roedos line ensures proper aging and a ready supply, allowing for flexible process adjustments. 

CMC's Lime Post Treatment Modules excel in biosolids processing.  Adding quicklime to dewatered sludge cake creates stabilized and/or disinfected biosolids.  These modules require less lime than other systems, reducing costs. Additionally, the reversible conveyor allows for complete bypass when unnecessary, enhancing operational flexibility.
