Detailed introduction to polyaluminium chloride

Polyaluminium chloride is a common water treatment agent. It is a colorless and transparent liquid and can be widely used in sewage treatment, tap water purification and other fields. The main function of PAC is to coagulate suspended and colloidal substances in water into large particles, which facilitates subsequent filtration and precipitation.

The chemical formula of PAC is [Al2(OH)nCl6-n]m, where the values of N and M vary according to the production process and application field. Generally speaking, the aluminium content of PAC is higher than that of aluminate and aluminium hydroxide, but lower than that of aluminium sulfate.

The mechanism of action of PAC is to purify water body in two ways. First, the chloride ion in PAC can react with alkaline substances in water to produce such substances as aluminium hydroxide and sodium chloride. These substances form a colloidal substance with strong electrical properties, which forms positive charged particles in water and can adsorb with negatively charged colloidal substances in water.

Secondly, aluminum ions in PAC can form polymer chains and interact with colloidal substances in water to produce larger aggregates. These agglomerates are easily precipitated or filtered out due to their high weight. In this way, PAC can effectively remove suspended and colloidal substances from water.

Polyaluminium chloride has a wide range of applications. It can be used to treat sewage, industrial waste water, domestic waste water, etc. Polyaluminium chloride can be used with other water purifiers to form an efficient treatment scheme for wastewater and industrial wastewater. In sewage treatment, PAC can be used as a separate treatment agent, which can effectively remove suspended and colloidal substances in water, making water cleaner and more transparent.

It should be noted that proper dosage should be paid attention to in the application of PAC. Excessive dosage will result in high residual chloride ion concentration in water body, which will have a negative impact on water ecological environment. At the same time, PAC may also produce odors which affect the taste of water. Therefore, in the application of PAC, it is necessary to select the appropriate dosage according to the specific water quality.
