Dewatering Sludge
Sludge dewatering is the practice of minimizing waste by volume to prepare for its effective disposal. Dewatering the sludge with a dewatering filter press significantly reduces its weight and its volume before disposal. Digested sludge is put through large centrifuges that work in the same fashion as a washing machine spin cycle. The spinning centrifuge produces a force that separates the majority of the water from the sludge solid, creating a biosolid substance. Wastewater treatment involves several key components: physical treatment (i.e. screening and filtering processes), biological treatment (i.e. oxidation ponds and lagoons), and chemicals. The chemicals required for water treatment must be used more aggressively and in larger quantities for wastewater than municipal drinking water. As such, safe, proper storage for wastewater treatment chemicals is critical.
