Our sludge dryers use advanced heat pump technology and a closed cabinet drying system. This machine recycles the waste heat generated in the drying system which increases the efficiency and lowers the energy needed to dry sludge. The insulated closed cabinet low temperature dryer operates at a temperature of between 120 – 185 fahrenheit.

Sludge Dryer. Sludge Dryers manufactured by Met-Chem are designed for small, medium and large quantity sludge generators. These dryers can fit under the filter press for direct loading or can be located elsewhere in the plant. The sludge is dried by the heated liner of our unit while it is broken-up and circulated by our spiral blade system.

wastewater treatment - wastewater treatment - Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.

Jun 18, 2020 · A belt filter press (BFP) provides sludge dewatering by pressing the sludge to force the water through a permeable medium. The process produces a cake (the dewatered product) having a dry solids (DS) content of 30% or more in the case of primary sludge. This is to be distinguished from the lower-energy gravity belt thickener process which

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