White PAC Powder 30% PolyAluminium Chloride for Urban Drinking 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.
The polyaluminum chloride having a content of aluminum oxide between 27 and 30 is mostly khaki-yellow yellow solid powder. These types of polyaluminum chlorides have relatively good water solubility, and in the course of dissolution, physicochemical changes such as electrochemical, agglomeration, adsorption, and precipitation eventually lead to [Al2(OH)3(OH)3] precipitation, thereby achieving the purpose of purification. In the use of polyaluminum chloride, without the need for other additives, floe formation is fast and thick, high activity, rapid precipitation, and a clear effect on high turbidity water purification.
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. The aluminum content of ordinary polyaluminum chloride, which is yellow polyaluminum, is significantly lower than that of white polyaluminum chloride. In potable water treatment, in order to accelerate the reaction rate, a high content of polyaluminum chloride is used, and, The basicity of salt is also an important factor in the reaction of polyaluminum chloride products. The normal yellow polyaluminum chloride has a salty degree of 80% or 90%, while the white polyaluminum chloride has a salty basicity of only about 50%. That is, ordinary polyaluminum chloride has a high content of heavy metals. Excessive heavy metal content will affect the safety of drinking water. In summary, common polyaluminum chloride cannot be used for the treatment of potable water, while white polyaluminum chloride is more suitable. Used in potable water treatment.
Polyaluminum chloride properties:
1. The purified water quality is better than aluminum sulfate flocculant, and the water purification cost is 15-30% lower than that. 2. The formation of flocs is quick and the settling speed is fast, which is greater than that of traditional products such as aluminum sulfate. 3.consumption of water below the alkalinity of various inorganic flocculants, which can not vote or less alkali agent. 4. The source water PH5.0-9.0 can be condensed. 5. small corrosion, good operating conditions. 6. the solubility is better than aluminum sulfate. 7. Less salt increase in treated water is beneficial to ion exchange treatment and high purity water production. 8. The adaptability to the source water temperature is better than inorganic flocculants such as aluminum sulfate.

The cost of polyaluminum chloride water is 20~80% lower than other inorganic coagulants; It can quickly form flocs, and has large flocculation and quick settling speed; It adapts to various temperature water sources and has good solubility; Liquid products can adapt to automation Dosing, corrosion is small, convenient operation, and long-term use does not block the tube. If customers have special requirements on quality, they can produce according to the indicators provided by customers. 1, a wide range of applications, adapt to a wide range of water. The water purification effect is obvious, the turbidity rate is as high as 96%, the decolorization rate is 60%, and the COD removal rate is 50%. This can effectively remove the color elements SS, COD, BOD and heavy metal ions such as potassium, lead and mercury, oils and humus, etc. . 2, flocculation and sedimentation speed, overdosage will not cause water turbidity, the water temperature is low, it can still maintain a stable coagulation effect. 3. Its degree of alkalization is higher than other aluminum salts and iron salts, and it is less corrosive to equipment. 4, a wide range of suitable PH value (5-9).
PolyAluminium Chloride Application Area:
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.
PolyAluminium Chloride Instructions:
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.
PolyAluminium Chloride Precautions:
a. Water treatment agents of different manufacturers or different brands cannot be mixed and must not be mixed with other chemicals. b. The stock solution and diluent are slightly corrosive, but lower than other inorganic coagulants. c, product effective storage period: liquid for six months, solid two years. Solid products can still be used after the tide. d. After the product is properly dosed, the purified water meets the potable water hygiene standards.
