Introduction: Effective Water Disinfection with Chlorine Dioxide
Chlorine dioxide (CLO2) is a powerful, broad-spectrum disinfectant used to eliminate harmful microorganisms, including bacteria, viruses, and protozoa, in drinking water, wastewater, and industrial process water. Unlike chlorine, CLO2 does not produce harmful byproducts like trihalomethanes, making it ideal for achieving stringent water quality standards. Precise dosing of CLO2 is critical to ensure effective disinfection, prevent overdosing, and maintain compliance with regulatory standards such as EPA or WHO guidelines.
Premix Technologies, based in Ahmedabad, Gujarat, India, designs advanced CLO2 Dosing Systems for water treatment applications. Our systems integrate agitators for homogeneous CLO2 solution mixing and automated dosing pumps for precise injection, ensuring optimal disinfection. With robust safety features and global standard compliance, we provide reliable solutions for municipal water treatment, wastewater management, and industrial water systems.
