A Coupling Process of Precoating Dynamic Membrane with Photocatalysis for Treatment of Oily Wastewater

Abstract:

In order to improve the steady permeate fluxes during the emulsified oil wastewater treatment using precoated dynamic membrane, a coupling process of precoating dynamic membrane with ultraviolet photocatalysis was studied. Impacts of the ultraviolet light power, pH values and the oil concentrations on improvement of the steady permeate fluxes were investigated. The results showed that the ultraviolet photocatalysis effectively improved the steady permeate fluxes and reduced the membrane fouling resistances during the emulsified oil wastewater treatment. The dynamic membrane steady membrane fluxes increased with the rise of ultraviolet light power and decrease in liquid pH values and oil concentrations. Impact of the ultraviolet photocatalysis on the oil retention ratio of precoating dynamic membrane was not obvious.
