Polyferric sulfate is a new, high-quality and high-efficiency ferric salt inorganic polymer flocculant. It has excellent water purification effect and good water quality after purification. The morphological character is light yellow amorphous powdery solid, which is very soluble in water. The 10% (mass) aqueous solution is reddish brown transparent solution with strong moisture absorption. It can be used for the treatment of industrial wastewater (such as printing and dyeing wastewater), and is also widely used in casting, medicine, tanning and so on.
As an inorganic polymer coagulant with superior performance, polyferric sulfate has the following characteristics:
1. Efficient and fast. It is a high molecular polymer with strong adsorption capacity and better water purification effect than other agents; The flocculate formed after dosing is large, with fast sedimentation speed, good hydrophobicity and easy filtration;
2. Strong adaptability. It has strong adaptability to various raw water and pH value of 4-11. Regardless of the turbidity of raw water and the concentration of wastewater pollutants, the purification effect is remarkable;
3. Less dosage and no precipitation. The utility model has the advantages of convenient operation, small dosage and low cost. Compared with ordinary polyferric sulfate, the dosage of reinforced polyferric sulfate is reduced by more than 20%, the alkalinity consumed is reduced by more than 30%, and there is no sediment in the product quality.
Polyferric sulfate is a cationic flocculant with polyhydroxy and polynuclear complex. Its aqueous solution contains a large amount of polymerized iron complex ions, which can electrically neutralize the colloidal particles of suspended solids in water, reduce the potential, and quickly condense the colloidal particles in water into large particles. At the same time, it also has the function of adsorption and bridging, so that the colloidal particles in water can quickly condense into large particles. At the same time, it also has the function of adsorption and bridging, so that the particles can condense into large particles, Accelerate particle sedimentation to achieve the purpose of water purification.
