What is Sludge Dewatering & What is it Used For

Apr 23, 2019 Simply stated, “sludge” is a semi-solid slurry that can be produced from a variety of industrial and municipal processes. The purpose of sludge dewatering is to reliably and efficiently concentrate the wastes into high solids filter cakes for easy and cost-effective disposal. Disposal of sludge is governed by strict regulations.
