Ferric sulfate

Details:

Poly Ferric Sulfate, PFS is a high-efficiency unorganic coagulating agent,chemically inactive,soluble in water.In water treatment,it hydrolysis to many electropositive multinucleated ion which neutralized negative charge of colloidal particle in water and adsorption colloidal particle,through adhesion,bridges,cross-linking made particles flocculation and sedimentation. Item Liquid Solid GB14591( I ) GB14591( II ) Fe2O3, %≥ 11 18.5 Fe2 + % 0.15 0.15 Basicity% 9.0-14.0 9.0-14.0 PH(1% water solution) 2.0-3.0 2.0-3.0 As %≤ 0.0008 0.0008 Pb %≤ 0.0015 0.0015 Water-insoluble matter, %≤ 0.5 0.5 Performance: 1. rapid sedimentation,good flocculation. 2. Excellent effect on water purifying.,remarkable function on decoloration deodorization,dehydration,deoiling,sterilization,removal of heavy metal ions in water,radioactive substances and carcinogens,strong ability to remove COD,BOD. 3. Stable property,it's solution can long-term storage. 4. It has wide range of PH Value:from 4-11,when 6-9 is best.The PH Value changes very little after water treatment,and reduce the hardness of water. Use: Mainly used on various industrial wastewater treatment,such as paper-making wastewater, municipal wastewater,oily wastewater,beneficiation wastewater and chemical wastewater treatment.
