Water Quality and Pollution Assessment

This study aims in understanding the physical, chemical and biological conditions of Kattigenahalli Lake.This Lake is situated in Kattigenahalli, Yelahanka.This is not being used by residents due to unknown reasons.This work aims in treating the lake water using organic purification which consists of three bio coagulants, which are Moringa oleifera, Tamarind seeds and activated charcoal using rice husk.These were used as locally available natural coagulants in this study to reduce turbidity and other parameters.Optimum dosage of Moringa oleifera seeds Powder, Tamarind seed powder and activated charcoal of rice husk was found to be 0.4g/l, 1g/l and 3.5 g/l respectively.The percentage reduction in turbidity after treating the lake water with Moringa Oleifera Seeds Powder, Tamarind Seeds Powder and Activated Charcoal from rice husk was found to be 24.07%,65.82% and 78.14% respectively.Among the three Biocoagulants used, activated charcoal was found to be the best as it reduced 78.14% of turbidity of the lake water.
