Reaktif Boyama Atıksularının Temiz/Tuzlu Su Olarak Geri Kazanımı: Membran Temelli Süreç Tasarımı Ve Membran Kirlenme Analizi Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep; Yılmaz, Levent(2017-08-15) Tekstil sanayinde renk verme amaçlı uygulanan reaktif boyama prosesi, yüksek düzeyde tuz, toplam organik karbon (TOK), renk ve askıda katı madde içeren atıksuya sebep olmaktadır. Bu atıksuların konvansiyonel metotlarla arıtılarak alıcı ortama deşarj edilmesi, bir yandan renk problemi ile birlikte tuzlanmaya sebep olurken, ham maddelerin geri kazanımını da olanaksız kılmaktadır. Bu çerçevede; geri kazanımı olanaklı kılan membran temelli süreçler, reaktif boyama atıksuları(RBA) için önemli bir alternatif...
A life cycle assessment of the membrane processes applied for salt recovery in reactive dyeing Şimşek, Naz Zeynep; Yetiş, Ülkü; Department of Environmental Engineering (2022-8-26) Reactive dyeing in the textile industry requires the addition of a significant amount of salt and generates wastewater that is high in pollution load and particularly high in salt concentration. In the literature, a variety of Best Available Techniques (BATs) for the reduction of salt consumption in reactive dyeing and the reuse of treated wastewater are available. Among these techniques, Ultrafiltration (UF), Nanofiltration (NF), and combined UF+NF systems appear as the most efficient BATs, as they can pro...
Process optimization on clean water recovery from real reactive dyeing effluents by nanofiltration Koçer Oruç, Burcu; Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep; Department of Environmental Engineering (2017) Clean water recovery from the reactive dyeing effluent of a cotton textile mill with membrane filtration was investigated. Lab-scale experiments were performed with wastewater samples taken from the last three steps of the dyeing line, comprising four sequential baths of dyeing, warm rinsing, washing with soap, and lukewarm rinsing. Waste dyeing bath was deliberately excluded considering its extremely high salt and color contents. Two sets of experiments were performed; direct nanofiltration (NF) and NF wit...
Fouling analysis for different ultrafiltration membranes in reactive dyeing wastewater treatment Zaf, Ruken Dilara; Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep; Department of Environmental Engineering (2017) Textile industry produces wastewater that is often very rich in salt and color, containing residues of dyes and other chemicals. Treating this wastewater to exceptionally high quality standards, typically for reuse purposes, necessitates advanced treatment methods among which membrane technology is a leading one. However, membrane fouling which can be caused by dissolved and particulate solids appears as the major limitation with the use of membranes in wastewater reclamation that leads to reduced efficienc...
Treatment of reactive dyeing wastewater and recovery of brackish water by applying ultrafiltration Erkanlı, Mert; Yetiş, Ülkü; Çulfaz Emecen, Pınar Zeynep; Department of Environmental Engineering (2016) Reactive dyeing wastewaters (RDW) originating from textile industry are highly colored and have high total organic carbon (TOC), turbidity and salinity content. Ultrafiltration (UF) scenario suggested here aims to keep salt in permeate and reuse resulting permeate in dyeing process. For this purpose, RDW samples were treated with 5 kDa PES and 2 kDa Thin Film GE Osmonics UF membranes. After single stage filtrations, two stage “5 kDa+5 kDa”, “5 kDa+2 kDa” and “2 kDa+2 kDa” applications were carried out at 2 ...
