Physicochemical parametric and water quality index (WQI) analysis of Gomti River, Lucknow using MDSSS

This research work was carried out to analysis of different physicochemical parameters and water quality index of Gomti River to examine the quality of water before directly using for different activities like municipal consumption, recreation, and other purposes. The Gomti River water polluted with various sources like industrial waste, agriculture waste, and domestic waste who discarded waste directly into the river water and water quality deteriorating continuously. Hence, the influence of the ecosystem as well as domestic activities due to water quality. Therefore, a modified double slope solar still (MDSSS) has been designed for the removal of this problem because it is cost-effective technology as compared to other conventional methods. After experimental work, analyzed various physicochemical parameters as well as WQI and found under the acceptable limit. Before solar distillation, these parameters showed that the quality of water not now in the safe limit, therefore needs to improve the quality of water but after solar distillation, all the parameters within the acceptable limit except turbidity, which was high even as NO3-, Cl- and F- are below the acceptable limit. The high level of pollutants disturbing the ecological system of rivers and affecting human health directly and indirectly.
