Study on Oily Wastewater Treatment with Multifunctional Ceramic Membrane

Abstract

We used cross-flow filtration method and made use of a certain degree of silicon carbide ceramic membrane at different filtration time, different operating temperature to treat with waste water so as to study the flux of membrane flux and the change of water quality and the amount of recoil cleaning on the recovery of membrane flux .The results show that: the silicon carbide ceramic membrane can effectively dispose the oily waste water. The energy consumption is lower and the membrane flux is stable, simultaneously, multiple recoil cleaning can also make the membrane flux fully recover when the filtration time is 15min, the membrane flux is large, the temperature is 35 degrees centigrade.
