Polyethersulfone (PES) membranes were used to separate wastewater from car washes containing bacteria.After the separation was completed, the UF installations were washed with chemical agents.The study examined how effectively these chemical agents remove bacterial contamination from the installation.P3 Ultrasil 11 alkaline solutions (pH = 12) were...

The resistance of automotive coatings to washing water recovered in 50% and 70% from wastewater generated at car wash was tested. The wastewater was purified in the ultrafiltration process using tubular polyvinylidene fluoride membranes (100 and 200 kDa) manufactured by PCI company. The membranes retained oil contamination and over 50% of surfactants....
Tubular ultrafiltration car wash wastewater
Open Research Data

The commercial ultrafiltration (UF) tubular polyvinylidene fluoride (100 and 200 kDa) and polyethersulfone (4 kDa) membranes were applied for filtration of carwash wastewater. Intensive fouling was notice, which caused over 50% permeate flux reduction during 3-5 h of filtration process. This phenomenon was reduced by washing the membranes with alkaline...
