River water Sabarmati is contaminated from the various sources viz industrial waste, domestic waste and other sources. River water is characterized for physico-chemical parameters at different location along the side of Gandhinagar- Ahmadabad and found unsuitable for drinking purposes unless treated by advance treatment technology. The Solar distillation unit developed and modified with three inbuilt basins system has been used for treatment of Sabarmati river water. The first step involved in the treatment of river water is to vaporize the water based on solar radiation allowed to interact with the three basins of solar distillation unit during vaporization and condensation. The rate of water, which is coming from the inlet tank, was measured and vaporized, condensed water was collected, after each hour during morning to evening (8:00am to 6:00pm).The data indicates the physico-chemical characteristics of river water existing at different location and physico-chemical characteristics of river water; after solar distillation treatment. Parameter such as pH, Turbidity, Ammonia, Nitrate, nitrite, sulphate, BOD and COD were found reduced due to deposition of contaminants by solar distillation process. The river water after solar distillation was found complied with the standard for intended use. Thus, the present solar based distillation unit, under solar radiation treatment via vaporization, condensation was found effective and efficient for treatment of river water.
