ANALYSIS AND TREATMENT OF LANDFILL LEACHATE BY ELECTROCOAGUALATION/FLOCCULATION METHOD, BENGALURU

Leachate is a poisonous liquid formed when waste breaks down in the landfill and water filters through that waste. The present study has been carried out to characterize and treatment of leachates in landfill of Bengaluru. Herewith are three different leachate sample stages (fresh, 6months & one year) that were collected and 14 parameters were tested out of those. The results are tabulated and compared with standard values. They are temperature , pH, turbidity, BOD, COD, total dissolved solids, copper, total hardness, iron, chlorides, chromium, zinc, lead and sulphate. From these, some parameters were likely elevated compared with the standard values. Due to these increase in certain crucial parameters, the landfill leachate will surely affects the properties of the soil, sub-surface and ground water. So these leachate must be treated well.Treatment of Leachate can be done in physical, chemical ,biological and physico-chemical processes.This research focuses the characteristics of Homogeneous mixture of three Raw leachate samples and how it is treated by Electrocoagulation/Flocculation Method.
