The performance of reactive ceramic membrane and ozonaiton was investigated in pilot and full scales, in order to remove the non-biodegradable matters and newly emerged pollutants PPCPs from reclaimed water. Flat-sheet ceramic membrane made of Al2O3 was tested with pore size of 100nm. Pilot scale test was conducted with 50 m3/day, while the full scale reached to 15000 m3/day, which is believed to the largest using reactive ceramic membrane so far in the world. It was found that the effluent turbidity, CODCr and NH3-N were 0.32 NTU, &lt;20 mg/L and &lt;0.2 mg/L, separately; more than 91% BDOC and 99% PPCPs can be removed, their concentrations in effluent were less than 0.65 mg/L and 10 ng/L separately. Trans-membrane pressure can be controlled under 30 kPa during daily operation. Ozonation alone can oxidize most PPCPs in reclaimed water, but it is not good enough. The integration of ozonaton with ceramic membrane is able to reach almost 100% removal of PPCPs.
