Considering the high concentrations of ammonium, heavy\nmetals and organic contaminants in landfill leachate-contaminated groundwater,\nsingle-reactor-PRB may not be effective; for that reason a sequenced PRB has\nbeen developed. The major objective of this study is to investigate and compare\nthe adsorption performances of Granular Activated Carbon (GAC) which is a form of carbon processed to have\nsmall, low volume pores that increase the surface area, and Natural Zeolite (NZ) which is the aluminosilicate, on one hand and\ncombination of them in remediating landfill leachate-contaminated groundwater\non the other. To come close to this goal, a novel PRB in pilot scale was\ndesigned in Plexiglas column. Three parts of 5 cm heigh were considered to put\nthe reactive media in the middle of the column. The simulated groundwater contaminated with a COD concentration of 600\nmg\/l was supplied to the end of the column in upflow direction with a flow rate of 10\nml\/min. by a small pump. Results showed that GAC\nhas predominated NZ for COD removal. However, no significant removal of COD\ncould be observed by using only NZ as a reactive medium. In addition, using NZ\nand GAC layers simultaneously had no significant effect on COD removal.\nTherefore, due to NZ acting as a good adsorbent for ammonium and heavy metals,\nit is recommended that the NZ and GAC compartments should rather be considered\nas up-gradient and down-gradient barriers, respectively.<\/p>\n\n\n\n<p><strong>Key words:<\/strong> PRB, Landfill Leachate, Groundwater, Zeolite, GAC, COD Removal.<\/p>\n\n\n\n<p> Full paper:\u00a0<a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/V7n6P15.pdf\"><strong>PDF<\/strong> <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Waseem Yousef Daoud*(1) \u00a0(1).
