Membrane techniques for removal detergents and petroleum products from carwash effluents: a review

One of the most significant urban services is carwash, which generates large amounts wastewater containing a variety pollutants, including sand, gravel, suspended solids, surfactants, oil products, diesel cleaners, etc., that may cause environmental pollution when transferred to sewage system without any treatment. The effective treatment crucial prevent as well recycle water source. Contaminants are removed from carwash effluent using technologies. This review focuses on identifying and comparing efficiency advanced commercial modified membrane filtration techniques, meeting discharge standard regulations, treat impurities, especially detergents/surfactants (anionic surfactant) petroleum products (oil/grease). results this indicate ultrafiltration (UF) common technology for Additionally, adoption traditional pre-treatment processes be advantageous before utilization process treating wastewater; although conventional can produce high quality effluent, they less than systems.
