MUNICIPAL WASTEWATER TREATMENT USING PLANT EXTRACTS BY ADSORPTION TECHNIQUE

CIVIL ENGINEERING

Mangalore, one of the fastest growing and developing city in Karnataka. Hence the risk of water contamination increases in many folds. In light of that, the study area selected for investigation is the municipal waste water from Alvas engineering campus. The collected samples of water were analysed for parameters like pH, Nitrates, Chlorides, Sulphate, Carbonates and Bicarbonates, Total dissolved solids, Hardness etc. Seed powders of Moringa oleifera, Neem, Tulsi, and Soybean as natural absorbent and environmentally friendly antimicrobial agent is used for purification of wastewater for various purpose. In present study various doses of Moringa oleifera, Neem, Tulsi, and Soybean seed powder like 2.5, 5, 7.5, 10, 12.5 mg/l were taken and checked for the efficiency dose on raw municipal wastewater. After treatment of water samples with Moringa oleifera, Neem, Tulsi, and Soybean seed powder were analyzed for different parameter like pH, turbidity, TDS, TS, hardness, chlorides, alkalinity, and acidity. Application of this low cost seeds is recommended for eco-friendly, nontoxic, simplified water treatment where rural and peri-urban people living in extreme poverty are presently drinking highly turbid and microbiologically contaminated water.
