Landfill leachate treatment by batch multi-stage process using natural zeolite
Leachate from the Bikarac landfill of the Šibenik-Knin County in Croatia has been treated by batch multi-stage process consisted of few steps: treatment with lime with pH adjustment, aeration during 24 hours and sorption by natural zeolite. Overall process shows very good removal efficiency for Kjeldahl nitrogen, even 78.60 %, Chemical oxygen demand 55.34 %, turbidity 64.09 % and el. conductivity 38.12 %. All steps in multi-stage process contributed to decrease of these parameters, where the highest contribution achieves the treatment with lime and aeration. Analysis of results obtained by desorption shows high ability of zeolite to retain pollutants particularly at pH 6.65. This can be attributed to the high affinity of zeolite towards Kjeldahl nitrogen, e.g. ammonia in landfill leachates. Results indicate possible use of the natural zeolite as a permeable reactive barrier for prevention of groundwater pollution.
