Changes in morphology of flocs formed in different kaolin systems

Xu Hui;Xiao Feng;Wang Dongsheng;State Key Laboratory of Environmental Aquatic Chemistry,Research Center for Eco-Environmental Sciences,Chinese Academy of Sciences;  
The coagulation performances in different kaolin systems were investigated,and the results indicated that when AlCl3 was used as coagulant,the floc size increased with increasing the concentration from 10 mg/L to 20 mg/L in micro kaolin system,and when the concentration was 40 mg/L,the floc size decreased.The recovery factor in larger breakage rate(400 r/min) condition reached the smallest at 20 mg/L in micro-system.The strength factor and recovery factor in nano system were smaller under smaller concentration(10 mg/L),but when the concentration increased to 20 mg/L or 40 mg/L,they increased at smaller breakage rate(200 r/min)due to the bridging effects of nano particles.When Al30 was used at the same dosage,the floc size after regrowth and recovery factor decreased due to larger charge neutralizing ability.
