Abstract

Wastewater is one of the resources which is using, recently, for irrigation due to the scarcity of water resources. In this regard, using adsorbents such as zeolites is recommended to improve the indexes of the wastewater. The results show that although natural zeolite decreases the amount of pollutions, it decreases the PERMEABILITY of the soil, which could adversely affect the soil structure. This study was done in 2012 at Shahrekord University in which 21 PVC columns were used to study the effect of MODIFIED ZEOLITE particles on PERMEABILITY and quality of SEWAGE. The experiment consisted of two factors: the type of the microzeolite (natural zeolite, MODIFIED ZEOLITE) and application method of the micro zeolite (mixed, layered) with three replications in 7 treatments. Injection of SEWAGE into the soil was through flood irrigation and repeated fifteen times with a weekly frequency. Volume of SEWAGE used in each injection was equal to pour valume. In frequency injections of 1, 3, 5, 7, 11, 15, infiltration was measured by using Falling Heads. The results showed that treatment of MODIFIED ZEOLITE (included mixed, middle layer and layer on the surface) had the highest infiltration rate respectively and treatment with natural zeolite (included mixed, middle layer, layer on the surface) had lowest infiltration rate. Further, modified treatments decreased Na effluent rate 111 percent with respect to natural Zeolite and therefore caused modified treatments to decrease SAR amount to 45%, comparing to control treatments and 132% to natural zeolite. Ultimately the MODIFIED ZEOLITE increased the final infiltration rate of the soil and improved effluent quality.
