The treatment of low temperature and low turbidity water has always been one of the most concerned problems in water supply industry. Under the condition of low temperature and turbidity, the content of macromolecule particles in water decreased significantly. The amount of impurities in the whole floc has also been greatly reduced, which makes it difficult for the micro flocs formed to achieve the purpose of precipitation through collision. The main effect of low turbidity on water treatment is that impurity particles in water dissolve in a fine state in water. The role of the coagulant is to assist the coagulant to adsorb the bridging of the flocs, so that the small scorpion flocculation is integrated into the dense and compact striate. The small volume of flocs formed by coagulation is light and easy to penetrate the filter layer during filtration to increase the turbidity of the effluent. How to strengthen the treatment effect of low temperature and low turbidity water under the premise of reducing the treatment cost has become the main target in the domestic water resources field.
