Highlights
In order to produce satisfactory water quality fit enough to recycle and reuse for intended purposes, options in terms of combination of techniques appears to be the way forward for certain feed types such as oily wastewater and oil-water emulsions [1]
The NF flux obtainedthrough course filtration integrated with MF (CFMF) as a pretreatment was close to three-fold higher than that obtained without pretreatment
Feed Conditioning The vehicle wash wastewater as obtained from the settling tank of the gas station was subjected to high speed stirring (7000 rpm) to convert some of the floating oil droplets into emulsions and the resultant liquid taken in a membrane feed tank to be processed in a sequential step processing
Summary
In order to produce satisfactory water quality fit enough to recycle and reuse for intended purposes, options in terms of combination of techniques appears to be the way forward for certain feed types such as oily wastewater and oil-water emulsions [1]. Many researchers reported work on various treatment options involving conventional methods such as Biological treatment (BT), Activated carbon adsorption (ACA), Electrochemical oxidation (EO), Electro-Coagulation (EC), Chemical Flocculation (CF), Chemical Coagulation (CC), Ozonation (Oz) etc. In view of the inherent advantages associated with membrane separation techniques (MST), it has attracted a great deal of interest in comparison with conventional methods with regard to treatment of wastewater in general and oily wastewater or oil-water emulsion liquid streams in particular. Treatment of vehicle wash wastewater by MST has been reported in several studies [15,16,17,18]
