Virtues of industrial wastewaters completely depend on the type of process and products of the factory. Keeping this fact in mind, the greatest differences between industrial waste and municipal wastewaters could be as follow:  There is more possibility of existence of toxic chemical compound in the industrial wastewater. - It has more corrosive characteristic.  It conveys alkaline or acidic virtues, i.e. the range of pH variations is extensive.  Living creatures are less likely to exist in it. According to the performed researches, main polluting compounds of motor vehicle industry’s effluent include variety of dye compounds and heavy metals, COD, oil, grease and detergents etc. The staff and trade unit employees use sanitary services such as showers, toilets etc. in their work place. Consequently, a kind of wastewater is produced which is known to us as sanitary wastewater. The sanitary wastewater pollution is mainly a biological pollution and has a more constant combination than industrial wastewater. It is necessary to take some measures to avoid polluting the environment by both industrial and sanitary wastes and to keep their polluting level standardized. Also their refined waste could be used for different purposes. (Gerad Keily, 1998; Metcalf and Eddy, 1991; Qasin, 1999; Standard Methods, 1989). In performing the present study, the following goals were pursued:
