Abstract

Waterworks sludge from sedimentation process in conventional drinking water treatment plant, recovery tests under aluminum adding H2SO4, thickening and settling properties were investigated. Using H2SO4, was recovered 60-70% of the initial concentration of aluminum in the sludge, and pH=1.5 Und mixture 5-30 minutes. For testing the settleability and thickening Nalclear 8173 and Trafloc 496 polymers were used. With a significance level of 0.05, the settling properties significant for SST and turbidity removal was obtained; there were no significant differences between the polymers; dose efficiencies presented significant removal was 10 mg/L. In thickening, adding Trafloc and the time factor influenced significantly on removal efficiencies of COD, BOD, TSS and turbidity; there were no significant differences between the doses of polymer used. The settleability provided best technical conditions for the treatment of sludge tested.
