Experimental Investigations of a Solar Water Treatment System for Remote Desert Areas of Pakistan

Pakistan is among the countries that have already crossed water scarcity line, and situation worsened due to recent pandemic. This because major budget of country shifted primary healthcare activities from other development projects included treatment transportation infrastructure. Consequently, water-borne diseases increased drastically in past few months. Therefore, there a dire need address this issue on priority basis ameliorate worsening situation. One possible solution shift focus/load mega-projects require plethora resources, money, time small domestic-scale systems for treatment. For purpose, solar stills are designed, fabricated, tested one harshest climatic condition areas Pakistan, Rahim Yar Khan. A comprehensive overview regional climatology, including wind speed, potential, ambient temperature presented whole year. The analysis shows proposed system can adequately resolve drinking problems deprived Pakistan. average productivity 1.5 L/d/m2 achieved with total investment PKR 3000 (<$20). real site testing data will serve as guideline similar design arid globally.
