Polymeric ferric sulfate manufacturers: to introduce you to the characteristics of polymeric ferric sulfate
Polymeric ferric sulfate (Polymeric ferric sulfate manufacturers) According to its state, it is divided into liquid and solid. The liquid is a uniform reddish brown viscous transparent liquid with a specific gravity ≥ 1.45g / cm3 and a viscosity (20°C)> 10 centipoise. The solid is a light yellow amorphous powdery solid with strong hygroscopicity. Polyferric sulfate is a new type of inorganic polymer coagulant. It is non-toxic and harmless, chemically stable, and miscible with water. In the process of water treatment, polymeric ferric sulfate can quickly form a large amount of [Fe2(OH)3] 3,[Fe2(OH)2] 4,[Fe8(OH)20] 4 and other polynuclear complex ions, which are easy to form flocs and have good cohesive properties. And the consumption is low, the dropping speed is fast, the PH value is wide, the residual iron ion in the water is less, the hydrolysis product has excellent dehydration performance, the heavy metal removal rate is high, the effluent water quality is good, and the treatment cost is low. It is superior to other coagulants such as polyaluminium chloride, aluminium sulphate and ferric chloride.
Polymeric ferric sulfate (Polymeric ferric sulfate manufacturers) Features:
1. A polymeric iron sulfate based inorganic polymer coagulant having a molecular weight of up to 1x 105. In aqueous solution, OH-is used as a bridge to form a large number of complex ions, they can neutralize the surface charge of colloidal particles, and strongly adsorb colloidal particles by adhesion, bridging, cross-linking and rolling sweeping functions, so that the particles agglomerate to form flocculated precipitates, the surface area of the precipitates can reach 200-1000m2 / g, with great adsorption capacity.
2. Polymeric ferric sulfate (Polymeric ferric sulfate manufacturers) It has a wide range of PH value applications and has a good coagulation effect between PH5-11 and PH7-9, especially between two and three.
3. Polyferric sulfate has strong adaptability and can achieve good results for different water quality. The coagulation effect of high temperature and high turbidity water and low temperature and low turbidity water is ideal.
4. Polymeric ferric sulfate (Polymeric ferric sulfate manufacturers) It has a strong comprehensive treatment effect and is used for the treatment of industrial wastewater and domestic sewage. It not only has rapid flocculation, large particles and high strength, but also has the functions of decolorization, sterilization, radioactive elements, heavy metal ions and significant reduction of COD and BOD.
