Effect of Fe Coagulant on the Performance of PAC-MBR

Abstract:

For treating reservoir water from Yellow river, by dosing 2mg/L FeCl₃ to PAC-MBR, the effect of FeCl₃ coagulant on the performance of PAC-MBR was studied. It could be concluded that membrane had an absolute removal of particles, and the dosing of coagulant gave no influence on the removal of turbidity. The dosing of FeCl₃ coagulant could restrict the removal of ammonia, but there was still a relatively high removal rate of ammonia by 75%; the mechanism of coagulation could increase the removal of organic matter, from 23.05% to 36.39% for CODMn and from 14.68% to 24.78% for UV₂₅₄.
