Food Grade Liquid Polyferric Sulfate (Drinking Water Special)

Product features:

This food grade polyferric sulfate is prepared with high-purity raw materials and closed oxidation polymerization process. The content of all heavy metal residues is far lower than national food safety standards, fully meeting the requirements of FDA and GB2760. It forms flocs extremely quickly, forming dense flocs within a few seconds, greatly shortening the retention time of sedimentation tanks and improving the treatment capacity of water plants. At the same time, it will not form toxic aluminum-based by-products with organic matter in water, solving the health hidden dangers of traditional aluminum salt flocculants. Its low insoluble matter content will not cause filter blockage, extending the service life of filter media and reducing later maintenance costs.

Product specifications:

The appearance is reddish brown transparent liquid, the effective iron content is ≥10.0%, the basicity is 8.0%-12.0%, the insoluble matter content is ≤0.1%, the pH value (original solution) is 1.5-2.5, the heavy metal arsenic content is ≤0.0002%, the lead content is ≤0.0001%, the package is 1000L international standard IBC ton barrel, stored in a cool, dry and ventilated place, avoid direct sunlight, and transportation needs to comply with dangerous goods transportation specifications (non-dangerous goods but need moisture and sun protection).

Product application:

It is mainly used in the drinking water purification treatment of urban water plants, and has a particularly significant effect on the treatment of high turbidity raw water and water sources during algae outbreaks, effectively removing chroma, odor and micro-pollutants in raw water; it can also be used for water purification pretreatment of bottled drinking water and mineral water plants, and water purification treatment of swimming pools, ensuring clear and hygienic water quality. It is compatible with conventional water plant water purification processes, including mixing, flocculation, sedimentation, filtration and other links, and can be used directly without additional modification of existing equipment.
