Sewage Sludge Drying

After drying. There are many sludge left after wastewater disposal. The moisture content may be not high, but it's very pasty, very hard to dry. Our drying equipment use large volume low temperature technology to dry. Combining with rotary harrow and special leading and raising boards, we can dry sewage sludge to below 10% moisture content.

Sludge drying Sludge Processing

Sludge drying properties. Sludges of different origins and characteristics exhibit different behaviours when drying. These are most readily observed by correlating the mass water flux – the mass of water evaporated per unit surface area of solids per unit time (kg m-2 s-1) – against the moisture content of the sludge.This correlation normally reveals the three different drying
