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
