Design of a real time optimization of salt electro chlorination system for water treatment

Abstract

This project presents the design and development of a real-time optimized salt electro chlorination system for water treatment at Busitema University. The system aims to locally generate sodium hypochlorite, reducing dependency on costly and hazardous commercial chlorine supplies. Utilizing solar energy, an electrolytic cell, and an Arduino-based automation setup, the system precisely regulates salt and water dosages to ensure consistent and effective chlorine production. Key innovations include the integration of smart sensors, servo-controlled valves, and real-time monitoring to enhance disinfection efficiency and operational safety. Extensive experimentation was conducted to optimize operational parameters such as voltage, current, brine concentration, flow rate, pH, and temperature. Using Response Surface Methodology (RSM), optimal settings were established and validated through prototype testing, which achieved a hypochlorite concentration of 1090 ppm, energy consumption of 2.8 kWh/kg, and efficiency above 80%. The system supports Sustainable Development Goals by promoting clean water access, innovation, and energy-efficient solutions in resource-limited settings
