Membran filtrasyonu, tekstil endüstrisi atıksularının arıtımı için kullanılan en umut verici teknolojilerden biridir. Literatürde kirlenme kontrolü üzerine oldukça fazla sayıda çalışma yapılmasına rağmen, membran kirlenmesi son derece önemli bir sorun olmaya devam etmektedir. Bu çalışma kapsamında, işletilen bir tekstil endüstrisi atıksuyu arıtımı için işletilen anaerobik dinamik membran biyoreaktör (AnDMBR)’de meydana gelen membran kirlenmesinin karakterizasyonu yapılmıştır. Ayrıca eş zamanlı olarak işletilen mikrofiltrasyon (MF) membranı ile kıyaslanması yapılmıştır. Bu amaçla çalışmada, jel permeasyon kromatografisi (GPC), taramalı elektron mikroskopisi (TEM), Fourier Dönüşümlü Kızıl Ötesi Spektrofotometre (FTIR) ve kirlenme hızı (FR) analizleri gerçekleştirilmiştir. Kek tabakası oluşumunun ardından dinamik membran ile mikrofiltrasyon membranı benzer filtrasyon verimleri göstermiştir. Karakterizasyon analizleri ise dinamik tabakada 1 kDa’dan 9000 kDa’ya kadar geniş bir aralıkta moleküler büyüklüğe sahip partiküllerin büyük oranda mikrobiyal ürünlerce oluşmuş kek tabakası sayesinde filtrelendiğine işaret etmektedir. Yapılan TEM görüntülemesinde, MF membranında dinamik membrana kıyasla daha pürüzsüz ve gözeneksiz bir yapı gözlenmiştir. Dinamik membrandaki kirlenme hızı da MF membranınkinden daha düşük olarak elde edilmiştir.
