what is the sludge thickening process in water treatment

mar 06 2018· sludge flows into the thickening tank and eventually it removes excess water from the solids collecting at the bottom. a gravity thickener has a similar process to the tanks but it has a sloped design so that solids collect at the base. dissolvedair flotation is another type of sludgethickening process. small air particles attach to the

sludge thickeningabco

sludge drying beds are a simple and cost effective method of sludge dewatering. they reduce the water content of sludge by over 90% and the only power needed is that required to run two small pumps. they require no additional s or chemicals.
