Abstract

Mixing the wastewater of Industries with natural water has caused environmental pollution. So researcher tries to obtain methods and optimum conditions for wastewater treatment. One of Important stage in wastewater treatment is dissolved air flotation. DAF is used for the removal of suspended solids and oils from wastewater. In this paper, the effect of several parameters on flotation efficiency with Cationic Polyacrylamide as flocculants, was examined, namely, (a) concentration of cationic flocculants, (b) pH (c) fast mixing time, (d) fast mixing speed, (e) slow mixing time, (f) retention time and temperature. After dwesign of experiment, in each trial turbidity of wastewater was measured by spectrophotometer. Results show that contribution of pH and concentration of flocculants on flotation efficiency are 75 % and 9 % respectively. Cationic polyacrylamide led to a significant increase in the settling speed and effect of temperature is negligible. In the optimum condition, the outcome of the DAF unit is increased and amount of suspended solid and oil in wastewater is decreased effectively.
