The generation of alum sludge from drinking water purification process remains inevitable when aluminium sulphate is used as primary coagulant for raw water coagulation. Sustainable managing such the sludge becomes an ...
Concept and purpose
Virtually all water treatment facilities worldwide generate an enormous amount of water treatment residual (WTR) solids for which environmentally-friendly end-use options are continually being sought ...
In this study, dewatered alum sludge cakes were used as substrate in a laboratory
scale tidal vertical flow reed bed system treating animal farm wastewater. The
“tidal flow” operation was employed to enhance oxygen ...
