Quality of Leachate from Landfill with Reverse Osmosis Concentrate Recirculation

Izabela Anna Tałałaj

Abstract

The purpose of this study was to determine the changes of leachate quality on a selected municipal landfill with recirculation of concentrate from the reverse osmosis (RO) process. The research was carried out on an exploited municipal waste landfill, from which the samples of leachate, permeate and concentrate were collected in the years 2013–2015. The obtained samples were subjected to the physicochemical analysis, including the determination of general pollution parameters as well as organic and inorganic indicators. The obtained results showed that the concentrate recirculation resulted in intensification of the degradation processes in the waste body, expressed by the increase of biodegradability rate (BOD5/ COD) and the value of conductivity and dissolved solids. Over time, the value of conductivity and dissolved solids stabilized; however, they reached the values higher than in conventional landfills. A characteristic feature of the long-recirculation landfills was a continuous increase in the concentration of ammonia nitrogen and COD values in the leachate
