a study of treated municipal waste leachate and zeolite effects on soils

abstract- as the world's population has grown and become more urban and affluent, waste production has raised drastically. wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. to address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments of adsorbents (non-pretreated leachate (l1), rice husk filtered leachate (l2), activated carbon filtered leachate (l3)) and three levels of zeolite (0, 5 and 10% by soil weight).a decrease in drainage water volume through the experiment period was observed. application of zeolite at 5% level could improve soil removal efficiency and had a positive impact on the quality of the wastewater, as indicated by changes in ec, na+, ca2++mg2+, cl- (decreased by 22%, 15%, 24%, 15% respectively) and total p (increased by 12%) for treatment of leachate. however, adding 10% zeolite did not make a significant difference (p
