dispersion stability of drinking water treatment sludge

Dispersion Stability of Drinking Water Treatment Sludge

The objective of this study is to improve the particle suspension stability of drinking water treatment sludge (DWTS) and comparable to other silicate powder which are bentonite, micro silica (micro-SiO2), and nano-silica (nano-SiO2). The main dispersion characteristic are related to particle size, and dispersion force.

effectiveness of a drinking-water treatment sludge

Effectiveness of a drinking-water treatment sludge

Drinking-water treatment sludge (DWTS) produced at water treatment plants is an inescapable byproduct and has long been treated as a waste for landfill. In this study, a series of batch adsorption tests were conducted using a wide range of phosphorus (P) species to determine the adsorption capacities of freshly dewatered aluminium salt based DWTS.

What is the Sludge Thickening Process in Water Treatment

Sludge contains biosolids that have been removed from liquid sewage. Sludge thickening is the process used in wastewater treatment centers to increase the solids concentration and decrease free water. This step minimizes the load on sludge dewatering and digestion.
