Role of poly aluminium chloride in the treatment process of water purification

Poly aluminium chloride (PAC) is a widely used coagulant in water treatment processes due to its effectiveness in removing impurities and contaminants from water. Its primary function is to attract and neutralize suspended particles, colloids, and dissolved substances, allowing them to settle out of the water for easy removal. This helps improve the clarity and quality of the water for various applications. One of the key functions of poly aluminium chloride in water treatment is its ability to coagulate and flocculate suspended particles. When added to water, PAC forms floc particles that bind together and trap impurities such as dirt, bacteria, and organic matter. These floc particles then settle to the bottom of the water, allowing for easy removal through filtration or sedimentation processes. This helps to clarify the water and remove turbidity, improving its appearance and quality. Another important function of poly aluminium chloride is its ability to neutralize and remove dissolved substances such as heavy metals, phosphates, and sulfates. PAC works by forming strong bonds with these contaminants, causing them to precipitate out of the water and become trapped in the floc particles. This helps reduce the concentration of harmful substances in the water, making it safer for consumption and other uses

PAC can help kill bacteria, viruses, and other microorganisms present in water, making it suitable for drinking and other purposes. By flocculating and removing organic matter that serves as a food source for harmful bacteria, PAC helps to inhibit the growth of pathogens and protect public health. Overall, poly aluminium chloride plays a vital role in water treatment by enhancing the efficiency of various purification processes. Its ability to coagulate, flocculate, neutralize, and disinfect water makes it an essential component in the treatment of drinking water, wastewater, and industrial effluents. By using PAC, water treatment plants can achieve cleaner, safer, and more sustainable water supplies for communities and industries around the world. In conclusion, poly aluminium chloride is a versatile and effective coagulant that performs multiple functions in water treatment. Its ability to remove impurities, neutralize contaminants, and disinfect water makes it an essential tool for ensuring the quality and safety of water supplies. As the demand for clean water continues to grow, the use of PAC will remain crucial in meeting the challenges of water treatment and ensuring the availability of safe and potable water for all.
