Abstrakt: Raw samples of Kwashe open dump sites in the Iraqi Kurdistan region were taken and treated by aeration and filtration methods and 16 physicochemical properties of leachate were determined after and before treatments. Result indicates the efficiency of aeration and filtration in improving these physicochemical characteristics to extend limits. Sodium adsorption ratio and electrical conductivity are reduced by -%19.5 and -53.5%, respectively, but the leachate remained salty as organic waste of Duhok city contain huge amounts of edible salts. Result also revealed that the content of treated leachate of macronutrients like phosphorous, potassium, calcium and magnesium is sufficient for better crops production if it diluted with normal irrigation water and its EC is further reduced. The efficiency of aeration and filtration in reducing nutrients in leachate were in this rank Cl -18%>Ca-15%>Na-11% >Li-10.5% >Ba-9.8%> Mg-8.3% >K-7%> P-5.6% >S-5.2%.TDS and TSS respond to the aeration and filtration better than nutrients and reduced -47% and -45% resistively, but remained slightly over permissible limits of treated leachate. BOD and COD the most critical leachate properties were reduced by treatments -19.7% and -32% respectively, and further advance treatments is required to bring them to allowable ranges of treated leachate.
