Biosolids/Sludge Dryer K-S Paddle Dryer for Biosolids, Sludge, and Residuals Drying The K-S Paddle Sludge Dryer is used worldwide for drying a variety of sludges, biosolids and by-products, to generate dry stable products, reduce disposal cost and convert waste into marketable by-products. In municipal waste water treatment plants (MWWTP) the K-S Paddle Sludge Dryer System produces Class A Biosolids in accordance with the EPA’s 503 regulations allowing the dried granular material to be used beneficially as a slow release fertilizer or soil amendment. Dried waste products have also been used as fuel in boilers and cement kilns. Dual counter rotating shafts with unique intermeshing wedge shaped paddles produce uniform heating and high heat transfer rates. The use of hollow paddles for heat transfer results in a compact machine. Indirectly heated with steam or circulated thermal fluid (hot oil) the K-S Paddle Sludge Dryer has a thermal efficiency of approximately 98%. Non-condensable gas from the dryer that might require treatment for odors is minimal.

This video shows an overview of the K-S Paddle Dryer/Processor, its function, and the wide array of options available to fit your needs. This video is of an actual pilot test drying biosolids. Clearly shown are the various phases of drying: wet cake, plastic, shearing, wet granular, and dry granular. Being able to handle all phases of this process is what makes our dryer unique.
