High rate thickener design calculations
WebJun 18, 2024 · A common variant on the gravity thickener design is the picket fence thickener. This technology is fitted with a stirrer comprising a series of relatively closely-spaced vertical arms, and is therefore similar in appearance to a picket fence. For both designs, the sludge enters the centre of a cylindrical tank and flows out to the periphery. WebHigh-Rate Thickeners separate liquids from solids using hindered settling. Rotating rake arms collect settled sludge and move it toward the center discharge cone. They use minimal amounts of polymers/chemicals to drop the solids, making High-Rate Thickeners environmentally friendly.
