Description
Polyaluminum chloride (PAC) is a group of water-soluble salts that are commonly used as coagulants in water treatment. They are typically used in the purification of drinking water, wastewater treatment, and in the treatment of industrial effluents. PAC is derived from aluminum-based compounds and is known for its high efficiency in removing suspended solids and organic matter from water.
Some common uses of polyaluminum chloride include:
- Water Treatment: PAC is used in the treatment of both drinking water and wastewater. It works by coagulating and flocculating suspended particles, making them easier to remove through filtration or settling.
- Paper Industry: PAC is used in the paper industry as a retention and drainage aid. It helps improve the retention of fine particles in the papermaking process, leading to improved paper quality and production efficiency.
- Textile Industry: PAC is used in the textile industry for color removal and wastewater treatment. It helps remove dyes and other pollutants from textile wastewater.
- Oil and Gas Industry: PAC is used in the oil and gas industry for the treatment of produced water and drilling wastewater. It helps remove contaminants and solids from the water, making it suitable for reuse or disposal.
- Mining Industry: PAC is used in the mining industry for the treatment of mine wastewater and the removal of heavy metals and other contaminants.
