The effect of polyaluminum chloride on pH value

Polyaluminum chloride (PAC) is a commonly used flocculant widely used in the field of water treatment, especially in the treatment of wastewater and drinking water. The main component of PAC is aluminum hydrogen compounds, and the specific chemical formula depends on the preparation method and the different raw materials.

Polyaluminum chloride has a certain impact on the pH value of water. Here are some general situations:

Reducing pH value: The addition of PAC usually leads to a decrease in the pH value of the water body. This is because PAC contains hydroxide ions, which release hydrogen ions in water, making the water more acidic. This acidic change is usually mild, so pH monitoring and adjustment are required during the use of PAC.

PH adjustment is required: As the addition of PAC may lead to a decrease in the pH value of the water, pH adjustment may be necessary in some cases to ensure that the final pH value of the water meets specific requirements. This can be achieved by adding alkaline substances such as sodium hydroxide.

Different types of PAC: The impact of PAC prepared by different preparation methods and raw materials on the pH of water may also vary. Therefore, in specific applications, it is necessary to evaluate the impact of the specific PAC product used on pH value and take corresponding adjustment measures.

In general, when using polyaluminum chloride as a flocculant, it is necessary to closely monitor the pH value of the water and adjust it as needed to ensure the effectiveness of water treatment and meet the required water quality standards.
