Technology for treatment and recycling of wastewater of automobile service stations

ABSTRACT

A prototype treatment plant was fabricated and tested at varied hydraulic retention times for settling the suspended/settleable matter and skimming out oil and grease at laboratory plants of 40 L and 56 L. The results showed that 99.7% of oil and grease and almost all total suspended solids were removed and sparkling clear water was obtained, reusable for washing vehicles
