Performance and Efficiency of Azadirachta Indica, Guazuma Ulmifolia and Dolichos Lablab in Municipal Waste Diagnosis Process

The experiment was carried out at various dosages of the crude water extract by natural dry seeds. Using a jar test experiment, the experiment was carried out at various dosages of the crude water extract by dry seeds of Azadirachta indica, Guazuma ulmifolia, and Dolichos lablab. The optimum dosage of the coagulant was determined. Quality parameters of the waste waters were measured before and after treatment to assess the removal efficiency of major pollutants of concern in waste water treatment, such as suspended solids, COD, BOD, pH, TDS, Sulphates, and Chlorides. Azadirachta indica was found to be the most suitable natural coagulant for municipal waste water treatment when compared to Guazuma ulmifolia and Dolichos lablab. The use of a locally available natural coagulant for water treatment was found to be suitable, easier, cost effective, and environmentally friendly.
