Treatment of olive mill wastewater by different physicochemical methods and utilization of their liquid effluents for biological hydrogen production
Eroglu, Ela; Erolu, Inci; Gündüz, Ufuk; Yucel, Meral (2009-04-01)
in this study various two-stage processes were investigated for biological hydrogen production from olive mill wastewater (OMW) by Rhodobacter sphaeroides O.U.001. Two-stage processes consist of physicochemical pretreatment of OMW followed by photofermentation for hydrogen production. Explored pretreatment methods were chemical oxidation with ozone and Fenton's reagent, photodegradation by UV radiation, and adsorption with clay or zeolite. Among these different two-stage processes, strong chemical oxidants ...

The objective of this study was to investigate the performance of a pilot-scale membrane bioreactor (MBR) system for the treatment of a highly concentrated mixed wastewater from wet processes (dyeing, finishing, and sizing) of a denim producing textile industry. The MBR system, containing a Submerged hollow fiber membrane module in the aeration tank, was operated aerobically for about 3 months on-site at a continuous flow mode. The system was operated at two different operation stages: (1) 110 Sludge wastag...
Treatment of silk production wastewaters by membrane processes for sericin recovery
Capar, Goksen; Aygun, S. Seylan; Gecit, M. Rusen (Elsevier BV, 2008-12-01)
Sericin protein, although a valuable resource for many industries including cosmetics, pharmaceutical and biomedical, has been discarded as a waste in silk industry, causing environmental pollution. This paper describes determination of a membrane-based process for sericin recovery from cocoon cooking wastewaters (CCW) that will enable value-added utilization of waste sericin. The iso-electric point (pI) of sericin was found as 5-6, whose MW was distributed as 180-200, 70-80, 30-40 and 10-25 kDa. Prior to m...
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 ...
