Background

Sludge drying, also known as sludge dewatering, refers to a process of removing most of the water content from sludge by percolation or evaporation, and generally refers to the use of self-evaporation facilities such as sludge drying beds (beds). After the sludge is concentrated, the water content of the sludge is further reduced by a physical method, so that the sludge is convenient to transport, accumulate, utilize or further treat. In the sludge drying process, high-moisture content sludge is flocculated and concentrated to reduce interstitial water of the sludge, a conditioner is added for conditioning to destroy cell walls of microorganisms in the sludge to separate out intracellular water, and the intracellular water is further dehydrated through plate-and-frame filter pressing or low-temperature drying.
