Treatment of Sanitary Landfill Leachate with Peat

Leachate is generated by the action of water on the solid wastes deposited in sanitary landfills or dumps.in this project, peat was investigated as a means of removing metal ions from the leachate. Where peat is impregnated with the solution of Zinc Chloride to increase the capacity of adsorption. To find an alternative for fresh water resource in the places where drinking water standards are not required, leachate water recycling can be adopted. Wastewater is an immense resource which could have significant application in the regions of water scarcity. This project deals with eco-friendly treatment in which characteristics of leachate water before and after treatment are analysed and compared. It found that the approximate removal efficiency of peat to treat leachate is 76% for BOD, 42% for COD. The reuse of leachate water has a wide range of application in irrigation since it is within the appropriate standards of irrigation standards. The usefulness of peat in treating leachate depends on the type and concentration of the leachate. In order to be effective, large amount of peat may have to be used.
