Rotating biological contactor with immobilized Acidithiobacillus ferrooxidans was used to treat acid mine wastewater,the process properties of Acidithiobacillus ferrooxidans biofilm on the surface of rotating biological contactor were studied,and the influences of HRT,influent Fe2+ and rotation speed on the Fe2+ oxidation rate were investigated.

Wastewater treatment performance of a submerged rotating PVDF membrane bioreactor;

The process for wastewater treatment in submerged rotating membrane bioreactor(SRMBR) was studied.
