Tubular ultrafiltration car wash wastewater
Dane BadawczeThe 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...

Car wash water reuse
Dane BadawczeThe 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....

Biofouling UF car wash
Dane BadawczePolyethersulfone (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...

Separation of bacteria in UF process
Dane BadawczeLarge quantities of water are used in car washing, so it is necessary to recycle the water, which is made possible by membrane filtration. FP100 (100 kDa) membranes have been used to treat car wash wastewater by ultrafiltration (UF). With time of operation, the properties of the membranes change. The membranes need to be cleaned periodically to prevent...
