Sludge management in water treatment systems

Whether the goal is to produce drinking water, industrial water or purify wastewater, treatment always involves the management of solids, which the industry calls sludge.

Water treatment systems remove particles of all sizes, from molecular to coarse, which form sludge. Chemicals called coagulants and polymers are used to agglomerate particles to increase and densify the flocs. These products also make up some of the sludge.
