escription | Polyaluminum chloride is an inorganic polymer coagulant with the molecular formula [Al2(OH)nCl6-n·xH2O]m(m≤10, n=1~5). It is an inorganic polymer compound, a hydrolysis product between aluminum chloride and aluminum hydroxide. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, an inorganic polymer water treatment agent with larger molecular weight and higher electric charge is generated.
Polyaluminum chloride is an inorganic polymer coagulant, also referred to as polyaluminum, and the English abbreviation is PAC. BaiFuChem Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, it has a larger molecular weight and charge A higher inorganic polymer water treatment agent. In terms of morphology, it can be divided into two types: solid and liquid, and solids are divided into brown, yellow and white according to different colors. Polyaluminum chloride of different colors is also quite different in application and production technology. |
Product performance | a. As a water treatment agent, polyaluminum chloride has strong adaptability to various water quality, and is particularly effective for coagulation and sedimentation of high turbidity water. |
b. The purified water quality is better than inorganic coagulants such as aluminum sulfate, and the water purification cost is 15-30% lower than that. Flocs form fast and settle quickly. | |
c. High alumina content and small dosage, which can reduce the cost of water. | |
d. The source water PH value can be coagulated in the range of 5.0-9.0. | |
e. Low corrosiveness, good operating conditions, and better solubility than aluminum sulfate. | |
f. There is less salt in the treated water, which is conducive to ion exchange treatment and pure water preparation. | |
g. The adaptability to the temperature of the source water is better than that of inorganic coagulants such as aluminum sulfate, and the treatment effect on low temperature water is also better. The minimum precipitation temperature is -18°C. | |

2. Light yellow polyaluminum chloride
The light yellow polyaluminum chloride is second only to the white polyaluminum chloride in the medium and high series. It is mainly used for drinking water treatment. The content of heavy metals is relatively strict, especially the drinking water-grade polyaluminum chloride products we produce. , The water after treatment with it is clarified without precipitation, the content of AL2O3 is about 30 (±0.5), the powder is fine, the particles are uniform, the flocculation effect is good, the purification is efficient and stable, the dosage is small, and the cost is low. It is the major water of long-term cooperation. Special water treatment flocculant for plant. |
|
3. Golden-yellow polyaluminum chloride
Is currently the most widely used polyaluminum chloride on the market. It is an efficient flocculant used in sewage treatment with good flocculation effect, so whether it is industrial water supply, industrial wastewater, industrial water recycling and urban sewage treatment Is the best choice. |
|
4. Brown, brown and coffee-colored polyaluminum chloride
Is a water treatment product produced for the special requirements of individual customers for water treatment. The iron content is higher than other polyaluminum chloride product series, so the color is darker than golden yellow . It is effective for low temperature, low turbidity, high algae sewage, and is mainly used for the treatment of drinking water, urban water supply, industrial water supply and other aspects. |

Inorganic polymer | Polyaluminum chloride is an inorganic high molecular polymer. It has certain gelling properties and can be used as cementing material for refractory coatings, ultra-pure alumina products and refractory concrete. Polyaluminum chloride is a kind of high-valent polyhydroxy electrolyte, which can be regarded as the intermediate product of AlCl3 hydrolysis to Al(OH)3. The gel core is positively charged and the hydrolysis is acidic. The composition of this type of product is a mixed system composed of various water-containing complexes in a certain proportion under certain conditions. Its expression is [Al2(OH)n·Cl6-n]m, where n=1 to 5 and m≤10.
Best price Aluminum chlorohydrate 1327-41-9 Direct Manufacturer Due to the different preparation methods and properties, polyaluminum chloride can also be called hydroxyaluminum chloride, basic aluminum chloride, polyaluminum chloride and so on. The main physical and chemical performance indicators include alkalinity, pH, Al2O3 content and relative density. Polyaluminum chloride is rich in raw materials, low in cost, has the characteristics of not reducing the refractoriness of refractory concrete, strong activity at high temperatures, and can be hardened at room temperature when mixed with a small amount of coagulant. It is a promising cementing material. |
Polyaluminum chloride classification | Polyaluminum chloride is generally divided into three categories. The first is food-grade polyaluminum chloride, the second is drinking water-grade polyaluminum chloride, and the third is industrial-grade polyaluminum chloride. Different types of polyaluminum chloride have obvious differences in the use process and related indicators. |
Food-grade polyaluminum chloride is generally white powder in appearance, referred to as white polyaluminum. It is mostly used for drinking water treatment, pharmaceutical and cosmetic auxiliary materials, and some high-tech scientific researches. It is generally made by spray drying process. The content of polyaluminum chloride in alumina is more than 30%. | |
Drinking water-grade polyaluminum chloride has yellow or golden irregular particles. It is also made by spray drying process. It is the most important cleaning agent in paper mills, printing and dyeing plants, leather factories, power plants, urban sewage treatment and sewage treatment plants. One of the water potions. Drinking water-grade polyaluminum chloride generally has an alumina content between 26% and 30%. Generally, there are products with three specifications of 26, 28, and 30 on the market. | |
Industrial-grade polyaluminum chloride is usually brown or yellow in appearance, and generally adopts a drum drying process, which has an excellent use effect in wastewater treatment in Colombia. The content of industrial-grade polyaluminum chloride is between 22% and 30%. The specifications of industrial-grade polyaluminum chloride on the market range from 22 to 30, and there are big differences. | |
Coagulant | Coagulant refers to a chemical agent that can promote the coagulation and flocculation of colloidal particles in water, accelerate the formation of coarse particles, and make it settle quickly or filter easily. |
Coagulants include coagulants, flocculants, flocculants, etc. There is no strict unified definition and boundary for these terms. Coagulants are often mixed with flocculants and coagulants. | |
Commonly used coagulants include alum, polyaluminum chloride, activated silicic acid, polyacrylamide, magnesia bauxite, ferrous sulfate and ferric chloride, etc. The best effect is to use polyaluminum chloride and alum in combination. | |
Polyaluminum chloride is a new type of inorganic polymer coagulant. It is fundamentally different from traditional inorganic coagulants in that traditional inorganic coagulants are low-molecular crystalline salts, while the structure of polyaluminum chloride varies from multiple forms. It is composed of carboxyl complex, has fast flocculation and sedimentation speed, is suitable for a wide range of PH value, has no corrosion to pipeline equipment, has obvious water purification effect, and can effectively remove heavy metal ions such as SS, COD, BOD and arsenic and mercury in water. It is widely used in the fields of drinking water, industrial water and sewage treatment, and has the following characteristics: | |
1. The purified water quality is better than inorganic coagulants such as iron trichloride and aluminum sulfate, and the cost of water purification is relatively low. | |
2. Flocs form fast, settle quickly, and have greater processing capacity than traditional flocculants such as ferric chloride and aluminum sulfate. | |
3. The adaptability to source water temperature, turbidity, alkalinity, etc. is due to traditional flocculants such as ferric chloride and aluminum sulfate. | |
4. The adaptable source water has a wide pH value, and it can be condensed in the range of PH5.0-9.0, and the best effect is PH6.5-7.5. | |
5. Low corrosiveness and good operating conditions. | |
6. The solubility is better than ferric chloride and aluminum sulfate. | |
7. After the treatment, there is little residual aluminum and salt in the water, which is conducive to ion exchange treatment and preparation. |
