Polyferric сульфат в лечении воды

(1)Use detail: compared with other inorganic flocculant has the following characteristics: 1. A new high efficiency inorganic polymer flocculant iron salts; 2. Flocculation performance, alum dense settlement rate; 3. Excellent water purification, water quality, free of aluminum; chlorine and heavy metals and other harmful substances, nor to the transfer of iron ions in water, non-toxic, harmless, safe and reliable; 4. Turbidity; bleaching; off oil; dehydration; sterilization; deodorant; algae; Removal of COD; BOD and heavy metal ions and other effects significant; 5. PH value of water bodies to adapt to wide range of 4-11, the best range of PH value 6-9, purified water, PH value of the original total alkalinity range is small, less corrosive to the processing equipment; 6. On the slightly polluted; with algae; low temperature and turbidity of raw water purification significant effect on the high turbidity of raw water purification is preferred; 7. Less dosage, low cost, processing cost savings of 20% -50%. 8. Applicable to chemical engineering; oil; mining; electricity; iron and steel; mine; raw water purification; wastewater treatment; oil-water separation; waste silver recovery; medicine; leather; sugar industry and other industrial water and wastewater and drinking water coagulation purification. (2)Physical Properties: PFS has both solid and liquid. Reddish-brown viscous liquid is liquid. Is a pale yellow solid particles, the relative density of 1.45. Can produce a variety of high hydrolysis and polynuclear ions, colloidal particles suspended in water and in electricity, reduce the potential to promote cohesion between particles, while producing adsorption, bridging cross-linking and so on.
