In developing country like India, where Municipal Solid Waste (MSW) Management is at a nascent stage, open dumpsites lead to negative impact on the health and environment. Leachate generated from non-segregated MSW leachate has been a major concern. Biological treatment like PVA gel technology has been proved to be effectual for treating the MSW leachate. The current study was Current study was conducted out at Municipal Solid Waste based 12 MW Waste-to-Energy Plant in Ghazipur, eastern part of Delhi, India. Physio- chemically and anaerobically treated leachate samples were subjected to PVA gel reactor. Parameters like BOD COD and Hydrolic retention time (HRT) were changed to get the optimized the treatment efficiency of PVA gel on non-segregated MSW leachate. Number of samples were analyzed to get the optimum strength of PVA gel while reducing BOD, COD, and with varying duration of HRT. Observation concluded that partially treated leachate having BOD nearly 600mg/L, COD nearly 1500mg/L, HRT of 5hr or more and temperature range of 30-40°C have shown maximum treatment efficiency of PVA gel.
