Sludge is produced as a byproduct of wastewater treatment or sanitation systems such as septic tanks. Because it has a high water content, sludge is easier to dispose of if the water is removed. Sludge dewatering is simply the process of separating the solids from the liquids.
There are several methods for dewatering. Mechanical dewatering uses a press or centrifuge to squeeze out the liquid. Filtration uses filter bags to separate liquids from solids. The liquid can also be evaporated with just air or a dryer, but the process takes longer.
Dewatering does not treat the sludge, but it does make treatment easier. The method used to remove the liquid from your sludge will depend on how you’re going to dispose of it afterward. Reddi Environmental will evaluate your sludge and recommend the best way to dewater it.
