Evaluation of flocculation and dissolved air flotation as an advanced wastewater treatment.
A bench scale study was carried out in order to evaluate the applicability of dissolved air flotation (DAF) as an advanced treatment for effluents from three different domestic wastewater treatment processes, namely: (i) a tertiary activated sludge plant; (ii) an upflow sludge blanket anaerobic reactor (UASB); and (iii) a high-rate stabilization pond.
Optimization of flocculation/flotation in chemical wastewater treatment
An experimental investigation on flocculation/flotation for direct chemical treatment of municipal wastewater was carried out. It was demonstrated that flocculation units prior to flotation must be designed and operated differently to those used prior to sedimentation. Recommendations regarding design criteria both for the flocculation unit and the flotation unit are given.
