White PAC Powder 30% PolyAluminum Chloride for Urban Potable Water
Polyaluminum chloride is a water purification material, an inorganic polymer coagulant, and a polymer with a relatively large molecular weight and a relatively high charge of inorganic polymer produced by the bridge action of hydroxyl ions and the polymerization of polyvalent anions. Pharmacy. In form, it can be divided into two kinds: solid and liquid. The solids are divided into brown, beige, golden yellow and white according to different colors, and the liquid can be represented as colorless, transparent, yellowish, light yellow to yellow-brown.
In the treatment of potable water, the polyaluminum chloride coagulant used can only be white polyaluminum chloride, but it cannot be yellow common polyaluminum chloride. Why is this?
Yellow polyaluminum chloride is abbreviated as PAC, which is a water-soluble inorganic polymer polymer between ALCL3 and AL(OH)3. White polyaluminum chloride is spray-dried from aluminum hydroxide powder and high purity hydrochloric acid. A white or milky white powdered fine powder, which melts when exposed to air, can only be used as a white polyaluminum chloride in the treatment of potable water. It cannot be a yellow polychlorinated chloride. The reason for aluminum is that it has a great relationship with the effective substance content and performance index of these two products.

It is mainly used for the purification of potable water and the treatment of industrial waste water and special water (such as oily sewage, printing and dyeing papermaking wastewater, sewage treatment, smelting sewage, radioactive substances, toxic heavy metals such as Pb and Cr, and fluorine-containing sewage, etc.) Drilling, tanning, metallurgy, papermaking and other industries.
In order to achieve the flocculation effect and economic benefits, the user can determine the dosage by experiments according to different raw water turbidity, different seasons and different pool shapes. The liquid product is formulated as a 5-10% aqueous solution, and the solid product is formulated as a 3-5% aqueous solution (calculated as the weight of the product). The higher the turbidity of raw water is, the thinner the solution should be, the more dosage is needed, and the flocculation effect is good.
Water treatment agents of different manufacturers or different brands cannot be mixed and must not be mixed with other chemicals.
The stock solution and diluent are slightly corrosive, but lower than other inorganic coagulants.
Product effective storage period: liquid for six months, solid two years. Solid products can still be used after the tide.
After the product is properly dosed, the purified water meets the potable water hygiene standards.
