Determination of optimal method for management of leachate membrane concentrate by analytical hierarchy process

Abstract

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 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%).

Öz

Bu çalışmada membran biyoreaktör (MBR) sonrası membran prosesler (ultrafiltrasyon+nanofiltrasyon) ile arıtımı sağlanan sızıntı suyunun membran konsantre akımının yönetiminde, çevresel, ekonomik ve sosyal açıdan en uygun yöntemin Analitik Hiyerarşi Prosesi (AHP) kullanılarak belirlenmesi amaçlanmıştır. Evaporasyon, dolgu sahasına resirkülasyon, yakma, katılaştırma ve ileri arıtım alternatif bertaraf metotları arasından en uygun yöntemin belirlenmesinde kriter olarak, konsantre sızıntı suyu hacmi, suyun kompozisyonu, arıtım maliyeti, halkın onayı ve uygulanacak yöntemin esnekliği kriterleri seçilmiştir. AHP, Expert Choice 11 programı kullanılarak çözümlenmiştir. Analiz sonucunda alternatif yöntemlerin tercih sıralaması; Dolgu sahasına resirkülasyon (%31.8)>katılaştırma (%23.8)>ileri arıtım (%21.5)>yakma (%16.3)>evaporasyon (%6.6) şeklinde bulunmuştur. Bu sıralamanın oluşturulmasında her bir kriterin ağırlığının sıralaması ise; arıtım maliyeti (%49.2)>konsantre suyun içeriği (% 27.0)>konsantre suyun hacmi (%13.5)>arıtım yönteminin esnekliği (%6.5) >kamuoyu onayı (%3.7) şeklinde sıralanmıştır.
