  • What is the Sludge Thickening Process in Water Treatment

    Mar 06, 2018· Rotarydrum thickeners are stainlesssteel drums with spirals and a flow system used to treat solids. The drum mixes sludge to reduce the water content, leaving a solid concentration behind. Water flows out of the drum for reuse. Wastewater centrifuge dewatering is another sludgethickening method suitable for a range of scenarios. They typically require less space than other sludge thickening
