Reclamation of Saline Water through Solar Desalinization Process under Arid/Semi-Arid of Thar at Umerkot District, Sindh, Pakistan

Abstract

Drinking water is essential necessitate for daily life as there is dearth of water in many parts globally. Water quality ought to be such that it can be used by persons for drinking purpose. There are already plenty of solar units present in the market that can do reclamation process, as the available desalinization solar units clean the water safe to drink In desalination process the removal of salt and other minerals from the water is carried out to make it suitable for human consumption and industrial use. Reverse Osmosis (RO) is the one and only one regularly used domestic filtration system that removes even all the impurities. RO is required if the Total Dissolved Solids (TDS) exceeds a certain value. The main objective of this project is to use the sun as source of energy through solar desalinization technique which cleans water for drinking purpose and installed three or four desalinization solar units at village level that operates on solar power. This study showed that 88 liters saline water provided the maximum drinkable water at the adjustment@6 liters/hr/panel at Arid Zone Research Institute, UmerKot. The performance of desalinization solar units installed at Goth Nawab Ji Dhani (Umerkot) using brackish water having 14.45 dSm salts removed the toxic salts through solar desalinization technique and reduced it to 0.15 dSm. Water having so minute salts is fit for drinking purpose. This system creates awareness to the local communities.
