Adding excessive coagulants, new coagulants, or flocculants, or other agents in coagulation treatment is called Water treatment equipment Enhanced coagulation. Water treatment equipment enhances coagulation and flocculation to remove as many organic substances and disinfection byproduct precursors as possible from water in conventional treatment processes (the organic substances here mainly refer to humic acid and fulvic acid).
Water treatment equipment The removal mechanism of coagulation and the main organic substances removed include: adsorption, neutralization, and aggregation of colloidal organic substances, adsorption and co-precipitation of dissolved organic substances by the large specific surface area of the metal hydroxide flocs formed by coagulation, and polymerization precipitation of humic acid and fulvic acid, etc. The enhanced coagulation of water treatment equipment mainly improves the removal mechanism of organic matter by enhancing the adsorption of organic matter by the flocs produced by coagulation. For example, under the same amount of chemical addition, the mechanical mixing clarifier is superior to the reaction tank-sedimentation tank process in terms of the removal effect of organic matter and disinfection byproduct precursors. The reason is that there are flocs in the mechanical mixing clarifier, and the flocs can fully exert their adsorption effect, while the flocs in the reaction-sedimentation process are precipitated after formation, and they have not fully exerted their adsorption potential.
Original enhanced coagulation measures in water treatment equipment include: changing from aluminum salt coagulant treatment to adding iron salt as a coagulant (iron salt is easier to form polymers with humic acid and fulvic acid than aluminum salt), reducing pH value (favorable conditions for forming polymers of humic acid and fulvic acid are pH values of 5-6), adding organic or inorganic flocculants, using new coagulants with flocculation effects (such as polysilicate iron salts, polysilicate aluminum salts, etc.), increasing the mixing and flocculation reaction time, and selecting clarification processes, etc. Water treatment equipment Simultaneous high-manganese potassium permanganate pre-oxidation and powdered carbon adsorption (such as using a composite agent containing potassium permanganate, powdered carbon, and coagulant) during coagulation can also enhance the coagulation effect.
