TREATMENT OF LANDFILL LEACHATE BY MEMBRANE BIOREACTOR AND ELECTRO FENTON PROCESS
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 8
Abstract
Land filling is one of the least expensive methods for disposal of municipal solid waste (MSW). Hence about 90% of MSW is disposed in the open dumps and landfill unscientifically, creating problem to public health and the environment. The leachate generated from the municipal landfill contains organic and inorganic pollutants, which make it unsuitable for discharge in natural bodies without any prior treatment. Advanced oxidation process (AOPs) are promising methods to treat effectively the recalcitrant substances present in landfill leachate. Among APOs fenton process is considered the most promising treatment for remediation of highly contaminated water. In this study electro fenton pretreated landfill leachate was treated by membrane bioreactor process and then post treated by electro fenton process. The pretreated values of parameters were taken from previous studies which has BOD/COD ratio 0.39. Membrane bioreactors have proven quite effective in removing organic and inorganic contaminants as well as biological entities from waste water. In MBR the membrane arrangement consist of hollow fiber membrane module having pore size of 0.1µm. After MBR process, the effluent quality did not meet the general Standards for discharge of environmental pollutants. But after post treatment all the parameters have met the relevant Indian standards for discharge as irrigation water and all the parameter except BOD and sulphide have met the relevant Indian standards for discharge in to inland surface water.
