| Abstract: | As raw water quality deteriorates and drinking water standards enhances gradually,traditional water treatment process of WTP is facing severe challenges.Therefore,within the field of technical reconstruction,UF membrane technique would have a high potential and value to be applied.Different types and concentration of particles in raw water impact the membrane flux and fouling differently.In this paper,the effect of different types and concentration of particles in raw water on membrane flux and fouling was investigated in order to lay a theoretic foundation for the application of UF membrane in the field of WTP technical reconstruction. |
