Abstract

Technologies are generally described for processes, compositions and systems for waste sludge dewatering. In an example, the process may include receiving a waste sludge including a water component and an initial content of suspended particulates. The process may include treating the waste sludge with a combination of flocculant produced byand a flocculant including chloride. The combination may be sufficient to flocculate at least some of the suspended particulates in the water component of the waste sludge and sufficient to produce treated waste sludge. The treated waste sludge may have a water component with a reduced content of suspended particulates. The process may include separating at least some of the water component with a reduced content of suspended particulates from the treated waste sludge to produce dewatered waste sludge.
