Poly Aluminium Chloride Uses

Polyaluminum chloride (PAC) is an inorganic polymer coagulant, also known as high-efficiency polyaluminum chloride or high-efficiency spray-drying polyaluminum chloride. It is between AlCl3 and Al(OH)3. It is a water-soluble inorganic polymer with a general chemical formula of [Al2(OH)nCl6-n]m, where m represents the degree of polymerization and n represents the PAC product. Neutral degree. When n=1~5, it has a Keggin structure of highly charged polymeric ring chain, which has a high degree of electrical neutralization and bridging effect on colloids and particles in water, and can powerfully remove micro-toxic substances and heavy metal ions.

Polyaluminum chloride (PAC) is an inorganic polymer coagulant that is widely used in the field of water treatment. It can effectively remove impurities such as suspended solids, colloidal substances and organic matter in the water, clarifying and improving the water quality. Polyaluminum chloride is not only used in municipal sewage treatment, but also widely used in drinking water treatment, industrial wastewater treatment, papermaking, printing and dyeing, petrochemical industry and other fields.

During the water treatment process, polyaluminium chloride electrically neutralizes and bridges colloids and particles in the water through its highly charged polymer ring chain, forming flocs and precipitating, thereby achieving solid-liquid separation. Its advantages include high active ingredients, low dosage, convenient transportation and storage, excellent flocculation performance, and good stability.

In addition, polyaluminum chloride can also be used as a decolorizing agent to remove the color of printing and dyeing wastewater, and is especially suitable for treating fluorine-containing wastewater, high turbidity water, and low-temperature low-turbidity water. In the paper industry, it can be used as a precipitant for pulp to improve paper quality and strength.

Avoid mixing with other chemicals: When storing and using, avoid mixing with other chemicals to prevent chemical reactions.

Wear protective equipment: Please wear gloves, goggles and other protective equipment before use to avoid direct contact with skin and eyes.

Adjust the pH value: Before using polyaluminium chloride, the pH value should be adjusted according to the water quality to obtain the best results.

Stirring and mixing: After using polyaluminum chloride, sufficient stirring and mixing should be carried out to ensure that the agent fully contacts and reacts with the pollutants in the water.

Pay attention to storage conditions: Polyaluminum chloride should be stored in a dry, ventilated place to avoid moisture and high temperature.
