The large amount of wastewater generated from textile industries, petroleum industries, chemical industries contains heavy metals, suspended solids, hazardous waste, oils, fatty acids, dyes, pigment etc. It is very important to improve the quality of contaminated water before it discharges into the water sources or use. In the current work, an efficient methodology has been developed to separate emulsified oil from wastewater. The emulsified oil is tried to separate by using poly silicate Ferro aluminium sulphates, a flocculent. In addition to the above, the maximum separation efficiency for the devolved process is also revealed. Using PSFA, up to 93.5 % separation efficiency is achieved, and the discussed methodology can separate emulsified forms of the oil without altering the efficiency. The dissolved solid and metal content are also considered as the controlling parameters for the separation efficiency. The optimum TDS and the metal content must be maintained at 560 mg/L and 2 mg/L, respectively, to attain maximum separation efficiency. |
