In this study, anaerobic treatment of synthetic textile wastewater containing a reactive azo dye, namely, Remazol Brilliant Violet 5R, was investigated. A fluidized bed reactor (FBR) was used in the study. Before the operation period, start-up of the FBR was completed in 128 days with an immobilized microorganism level of 0.069 g volatile suspended solids per g support material (pumice). Anaerobic treatment of synthetic textile wastewater revealed that 300 mg/L dye was removed in the FBR system. Chemical oxygen demand (COD) and color reduction in the system were approximately 60 and 94%, respectively. Under anaerobic conditions, formation of two sulfonated aromatic amines (SAAs) was detected due to anaerobic reduction of the dye. The SAAs were not degraded under anaerobic conditions. In addition to the anaerobic treatment, the effectiveness of aerobic treatment was investigated in order to further reduce the COD after the anaerobic treatment.

Application of ozonation and biotreatment for forest industry wastewater
Balcioglu, I. Akmehmet; Sarac, C.; Kivilcimdan, C.; Tarlan, E. (Informa UK Limited, 2006-12-01)
This research is focused on the integrated process for the treatment of bleached Kraft pulp mill effluents. Pre-ozonation of softwood and hardwood combined bleaching effluents at alkaline pH resulted in 50 and 44% COD abatement, respectively. Segregation of highly polluted streams of bleaching process can be recommended to reduce the cost of treatment since the COD removal yield of CEH effluents was higher than combined bleaching effluents. Moreover, biodegradability of CEH effluents in terms of BOD5/COD ra...
Anaerobic Digestability and Biogas Production Capacity of Pistachio Processing Wastewater in UASB Reactors
Gur, E.; Demirer, Göksel Niyazi (American Society of Civil Engineers (ASCE), 2019-08-01)
High volumes of wastewater with considerable levels of organic and phenolic compounds and solid material are produced during pistachio processing. There is not a commonly adopted treatment technology for the wastes produced during pistachio processing. The objective of this study is to evaluate the anaerobic digestability and biogas production capacity of pistachio processing wastewater in upflow anaerobic sludge blanket (UASB) reactors for the first time in the literature. The results indicated that pistac...
Anaerobic treatment of dilute wastewaters
Alptekin (Ener), Emel; Demirer, Göksel Niyazi; Department of Environmental Engineering (2008)
In this study, domestic wastewater was used to determine the anaerobic treatment performances of a dilute wastewater in one-phase upflow anaerobic sludge blanket (UASB) system and two-phase upflow anaerobic filter (UAF) and UASB system. The acidification performances of domestic wastewater were compared in UAF and UASB reactors. The degree of acidification is higher in UAF reactor (31%) compared to UASB reactor (18%) at 2 h hydraulic retention time (HRT) in the anaerobic treatment of domestic wastewaters. T...
Waste minimization in a bleach plant
Doğan, Ilgın; Guruz, AG (Elsevier BV, 2004-03-01)
In this study a steady-state model was developed for a six stage bleaching system in a pulp and paper industry. A FORTRAN source code was written to simulate the whole bleach plant. Different case studies were performed with the aim of decreasing the total amount of dissolved solids coming out from the six washers. Each stage of the sequence is composed of chemical additions and mixing, reaction in a retention tower, and washing. Unit operation models were formulated using mass balances on liquor, fibres, c...
Indigo dyeing wastewater treatment by the membrane based filtration process
Ünlü, Meltem; Yetiş, Ülkü; Department of Environmental Engineering (2008)
In the present study, the recovery of the indigo dyeing rinsing wastewater originating from a denim textile mill to the degree of reuse quality, which generally requires nanofiltration (NF), was investigated. In order to control flux decline and hence to maintain an efficient NF; coagulation, microfiltration (MF) and sequential MF plus ultrafiltration (UF) pretreatment process alternatives were tested. All pretreatment alternatives were optimized to reduce chemical oxygen demand (COD) and color load to NF. ...
