PolyAluminum Chloride (PAC) is a chemical compound that is used as a coagulant in water treatment processes. It is a highly effective and efficient way to remove impurities from water, making it safe for consumption.
PAC works by forming a dense floc, or a cluster of particles, in the water. This floc then settles to the bottom of the treatment tank, taking impurities with it. PAC also has a positive charge, which helps it to attract and neutralize negatively charged particles in the water.
Using PAC in water treatment has several benefits. It is more effective than traditional coagulants such as aluminum sulfate, it produces less sludge, and it can remove a wider range of impurities. It also has a longer shelf life and is more stable in a wider range of pH levels.
Yes, PAC is safe for consumption. It is approved by regulatory agencies such as the FDA and EPA for use in water treatment. However, it is important to follow proper dosage and handling guidelines to ensure its safe and effective use.
PAC is produced by reacting aluminum hydroxide with hydrochloric acid. The resulting solution is then processed and dried to form a powdered or liquid form of PAC. The production process may vary slightly depending on the specific manufacturer, but the basic steps remain the same.
