This product is synthesized from high-purity raw materials, with heavy metal content far lower than national standards. It dissolves quickly without additional preparation, making it easy to use. The flocs form quickly and densely, with fast sedimentation speed, effectively reducing the turbidity and COD of effluent. It solves the hidden safety danger of aluminum residue caused by traditional aluminum-based flocculants in drinking water treatment, and has no side effects on human health. It can also improve the taste and safety of drinking water, making it an ideal choice for drinking water purification projects.
This drinking water grade liquid polyferric sulfate appears as red brown transparent liquid. The effective substance content (Fe₂(SO₄)₃) is not less than 11%, basicity is 12-16%, pH value of stock solution is 1.5-2.5, density at 20℃ is 1.38g/cm³, and insoluble matter content is ≤0.1%. The heavy metal content (calculated as As) is ≤0.0005%, meeting the requirements of national drinking water safety standards. It can be packaged in 1000L IBC ton barrels or 25L plastic drums, and should be stored in a cool and dark place to avoid exposure to sunlight, with a shelf life of 6 months.
This product is mainly used in urban water plant drinking water purification, rural safe drinking water projects, bottled drinking water production water purification, small drinking water treatment station water purification and other drinking water treatment scenarios. It can effectively remove various impurities in drinking water, ensuring that the effluent meets the national drinking water hygiene standards. It is also suitable for the pretreatment of secondary water supply facilities to improve the water quality of residential tap water.
