NOVELTY - A special flocculating agent comprises 30-50 pts. wt. cationic polyacrylamide, 5-8 pts. wt. nanostraw material, 2-6 pts. wt. surfactant, 2-4 pts. wt. macromolecule viscosity reducing agent, 0.2-0.4 pts. wt. ammonium persulfate, 0.1-0.2 pts. wt. sodium bisulfite, 4-8 pts. wt. microbial inoculum, and 10-16 pts. wt. graphene sodium acetate. USE - Special flocculating agent used for plate-frame dewatering machine for sewage treatment. ADVANTAGE - The special flocculating agent: is economic, at low adding amount, it can obtain good use effect; can obviously improve the production efficiency or improve the solid content of the mud cake; convenient to dissolve, easy to dissolve in the water; and can improve the capture rate of the solid matter in the solid-liquid separation in the production process, and can effectively work in wide pH value range.
