- Abstract:
- Lowpressure membrane filtration represented by microfiltration and ultrafiltration is widely applied in drinking water treatment. However, membrane fouling during operation still restricts its further development. As one of the effective methods for mitigating membrane fouling， ozone oxidation and its combination technologies have been widely used in lowpressure membrane fouling control. This paper summarized the latest research progress on ozone oxidation and its combination technology including ozone catalytic oxidation, ozone/hydrogen peroxide, ozone/adsorption and ozone/coagulation for membrane fouling mitigation in drinking water treatment, and analyzed the removal efficiency and mechanism of various membrane fouling substance which were mainly natural organic matter. Finally, the development and application prospects of various combination technologies were illustrated as well.
