The Use of Poly Aluminium Chloride in Water Treatment
Water treatment is a critical process that ensures the quality and safety of drinking water for communities around the world. One of the most commonly used chemicals in water treatment is poly aluminium chloride (PAC), which has been proven to be highly effective in removing impurities and contaminants from water sources.
PAC is a type of coagulant that works by neutralizing the negative charges on particles in water, causing them to clump together and form larger particles that can be easily removed by sedimentation or filtration. This process is known as coagulation, and it is a crucial step in the removal of suspended solids, turbidity, and other pollutants from water.
One of the key advantages of PAC is its versatility. It can be used in a wide range of water treatment applications, including drinking water treatment, industrial wastewater treatment, and swimming pool disinfection. In drinking water treatment, PAC is typically added to raw water to remove particles such as clay, silt, and algae. In industrial wastewater treatment, PAC is used to remove heavy metals, oils, and other contaminants from industrial effluents. In swimming pool disinfection, PAC is used to kill bacteria and viruses in the water.

use of poly aluminium chloride in water treatment. It is also easy to handle and store, making it a popular choice for water treatment facilities around the world. Additionally, PAC has a low environmental impact, as it is biodegradable and does not contain harmful chemicals.
However, like any chemical, PAC should be used with caution. Excessive use of PAC can lead to the formation of discolored water and the precipitation of aluminum hydroxide, which can be harmful to human health if ingested. Therefore, it is important to follow the manufacturer's instructions carefully when using PAC in water treatment.
In conclusion, the use of poly aluminium chloride in water treatment is a cost-effective and efficient method for removing impurities and contaminants from water sources. Its versatility, low cost, and low environmental impact make it a popular choice for water treatment facilities around the world. However, it is important to use PAC with caution to avoid potential health risks.
