【Abstract】 Basic principles and advantages of pellet coagulation process are explained.In the process,the main function of PAC is to make particles in water lose their stabilization, coagulate and form ideal primary particles, and PAM is to strengthen the binding between primary particles and pellet flux. Therefore, the different dosing point of PAC and PAM are determined. Through the experimental study, the effects of PAC and PAM on analytical indexes(such as Ct,ρ e and df) and their suitable ranges are obtained.更多还原
