Polyaluminium Chloride (PAC) is an inorganic polymer flocculant widely used in the field of water treatment. Based on its production process and product form, PAC can be divided into several types, each with its unique advantages in different application scenarios.
Below are the main classifications of PAC:
Classification by Alkalinity：
Low Alkalinity PAC: Alkalinity below 40%, mainly used for drinking water treatment and high-standard industrial water treatment.
Medium Alkalinity PAC: Alkalinity between 40% and 70%, suitable for municipal sewage and general industrial wastewater treatment.
High Alkalinity PAC: Alkalinity above 70%, primarily used for high-concentration industrial wastewater and heavy metal wastewater treatment.
Classification by Form：
Solid PAC: Usually yellow or white powder, easy to store and transport, suitable for large-scale water treatment projects.
Liquid PAC: Yellow or colorless transparent liquid, convenient to use, suitable for small-scale or temporary water treatment needs.
Classification by Color：
White PAC: Higher purity, suitable for high-standard water treatment, such as drinking water and food processing water.
Yellow PAC: More common, suitable for general municipal sewage and industrial wastewater treatment.
Brown PAC: Mainly used for treating high-concentration organic wastewater and heavy metal wastewater.
Selection and Usage Considerations：
Choose the appropriate type of PAC: Select the appropriate alkalinity and form of PAC based on water quality and treatment requirements to achieve the best treatment effect.
Control dosage: Reasonably control the dosage of PAC to avoid overuse or underuse, ensuring treatment effectiveness and cost-efficiency.
Safe operation: When using PAC, pay attention to safe operation, avoid direct contact with skin and eyes, and wear protective equipment if necessary.
By reasonably selecting and using PAC, the effectiveness of water treatment can be significantly improved, meeting the water treatment needs of different fields.
