Removing Struvite from Wastewater Systems Modern Pumping

A wastewater treatment company in Canada uses a number of dewatering centrifuges to remove water from sewage sludge. After the sludge has been removed the water is purified and then discharged. Purification occurs in the sludge dewatering centrifuge where the centrifuge's force separates the sludge from the water.

Optimization and modeling of reduction of wastewater

In "conventional" methods, reduction of sludge water content is performed mostly by mechanical or electrical dewatering processes. Common steps used for thickening and the reduction of sludge water content involves addition of inorganic (ferric or aluminum chloride) or organic flocculent (polyelectrolyte).
