Dewatering in biological wastewater treatment: A review

Oct 01, 2015Thus, several solid–liquid separation processes are involved in wastewater treatment for separating sludge from the treated wastewater as well as for sludge dewatering. The dewatering process is costly, and the composition and properties of the sludge are important for the separation process ( Bruus et al., 1992,Sørensen and Sørensen

What is Sludge DewateringWhat is it Used For

Apr 23, 2019Sludge dewatering is the practice of minimizing waste by volume to prepare for its effective disposal. Sludge originates during the process of treating wastewater before the water can be released back into the environment. Long presenting a challenge for the water treatment industry, sludge is the by-product extracted from the slurry during the process of Read more ?
