In this study, it was aimed to determine the most suitable method in terms of environmental, economic and social aspects by using Analytical Hierarchy Process (AHP) in the management of leachate concentrate flow which is formed after leachate treatment by membrane bioreactor (MBR) following membrane processes (ultrafiltration+nanofiltration). For determining the most appropriate disposal method among the alternative methods of evaporation, recirculation to landfill, combustion, solidification and advanced treatment, criterias determined as; the concentrated leachate volume, the composition of water, the cost of treatment, the public approval and the flexibility of the method. AHP was analyzed using Expert Choice 11 software. As a result of the analysis, the preferred ranking of alternative methods was found as recirculation (%31.8)> solidification (%23.8)> advanced treatment (%21.5)> incineration (%16.3)> evaporation (%6.6). The ranking of the weight of each criterion of this ranking is; cost of treatment (%49.2)> composition of concentrated water (%27.0)> volume of concentrated water (%13.5)> flexibility of treatment method (%6.5)> public approval (%3.7).

Bu çalýþmada membran biyoreaktör (MBR) sonrasý membran prosesler (ultrafiltrasyon+nanofiltrasyon) ile arýtýmý saðlanan sýzýntý suyunun membran konsantre akýmýnýn yönetiminde, çevresel, ekonomik ve sosyal açýdan en uygun yöntemin Analitik Hiyerarþi Prosesi (AHP) kullanýlarak belirlenmesi amaçlanmýþtýr. Evaporasyon, dolgu sahasýna resirkülasyon, yakma, katýlaþtýrma ve ileri arýtým alternatif bertaraf metotlarý arasýndan en uygun yöntemin belirlenmesinde kriter olarak, konsantre sýzýntý suyu hacmi, suyun kompozisyonu, arýtým maliyeti, halkýn onayý ve uygulanacak yöntemin esnekliði kriterleri seçilmiþtir. AHP Expert Choice 11 programý kullanýlarak çözümlenmiþtir. Analiz sonucunda alternatif yöntemlerin tercih sýralamasý; Dolgu sahasýna resirkülasyon (%31.8)>katýlaþtýrma (%23.8)>ileri arýtým (%21.5)>yakma (%16.3)>evaporasyon (%6.6) þeklinde olmuþtur. Bu sýralamanýn oluþturulmasýnda her bir kriterin aðýrlýðýnýn sýralamasý ise; arýtým maliyeti (%49.2)>konsantre suyun içeriði (% 27.0)>konsantre suyun hacmi (%13.5)>arýtým yönteminin esnekliði (%6.5) >kamuoyu onayý (%3.7) þeklinde sýralanmýþtýr.
