Pollutants of Painting Process in Automotive Industry "Case study: Paint Shop of Saipa Automotive Industry"

Produced paint sludge of automotive Industry has heavy metals and because of this, has high pollution potential. Incorrect Disposal of paint sludge led to kinds of environmental pollution. The object of this Investigation was identification of main pollutants of paint sludge that can be database to presenting profitable economic solution for recycling of that. For identifying elements and concentration of paint sludge, various tests have been carried out. These tests contains: XRF3, XRD4 and DTA. Results proved existing heavy metal elements like copper (1.5 gr/lit), zinc (13.09 gr/lit), Aluminum (58.76 gr/lit), Magnesium (23.004 gr/lit), Titanium (32.68 gr/lit), Vanadium (0.9 gr/lit) and etc. Comparing with environmental Standards showed that most kind of these elements are out of standard ranges and are noticeable pollutant elements. These results show the necessity of gaining solution for recycling of paint sludge. Then, more research about this case for deleting or decreasing pollutions is suggested.
