Design and construction of solar powered desalination system for salty borehole water

Abstract

Saline water treatment has become increasingly important for drinking water supplies. The aim of this study was to evaluate the effectiveness and design of solar powered electrocoagulation system with combined aluminum electrodes in removing the various types of salts from water samples collected at boreholes of Buwoya village in Namayingo district, taking into consideration a household of five people. The targeted type of salt include, total dissolved solids, chlorides, sodium, potassium, sulphates and hydrogen carbonates since there are responsible for causing salinity in water A bench scale consisting of the combined electrocoagulation configurations with static electrodes was implemented under solar power connections. The effects of factors such as reaction time, pH, temperature, inter electrode distance were observed to achieve a higher removal efficiency Since developing countries also tend to be poor, its people need low-cost, easy to operate and use and easily accessible desalination system. Design of various components was done using relevant formulae and equations It can be concluded that solar powered electrocoagulation is the best method with low costs involved
