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 wastage with a typical permeate flux of 20 L/m(2)h and (2) a solids retention time of 25 days with the same flux. During the whole operation period, despite the high dissolved solids content in the influent, very high treatment efficiencies were achieved. The performance of the MBR system was not adversely affected by the variations in the influent characteristics, food/microorganism ratio, organic loading rate, and specific substrate utilization rate. The average values of some effluent quality parameters found In the entire operation period were color, 53 Pt Cc; turbidity, 0.31 NTU; TSS, 0.6 mg/L; BOD5, 15 mg/L; COD, 37 mg/L; NH3-N 1.0 mg/L; NO3-N, 9.6 and TN, 10.5 mg/L. Reduction in permeate flux due to membrane fouling was observed only once during all operation and such fouling was removed by applying chemical backwashing and chemical cleaning procedures. The results indicated that complex and highly polluted denim textile wastewaters could be treated very effectively by MBR systems. Color values from as high as 8100 Pt Co levels were significantly reduced to about 50 Pt Co levels, indicating that MBR effluent could be reused in the production processes.

Microfiltration/ultrafiltration as pretreatment for reclamation of rinsing waters of indigo dyeing Uzal, Nigmet; Yılmaz, Levent; Yetiş, Ülkü (Elsevier BV, 2009-05-15) This paper focuses Oil the applicability of microfiltration (MF)/ultrafiltration (UF) as a pretreatment to nanofiltration (NF) for the reclamation of rinsing waters of indigo dyeing process. Two different MF alternatives, single 5 mu m MF and sequential 5 mu m + 0.45 mu m MF, were evaluated as prefiltration to improve the performance of the proceeding UF stage. UF tests performed after 5 pin MF Using 100 kDa, 50 kDa, 20 kDa, 2 kDa and 1 kDa membranes have indicated that all the UF membranes provided the sam...
Effect of color and surfactants on nanofiltration for the recovery of carpet printing wastewaters Capar, Goksen; Yetiş, Ülkü; Olceroglu, A. Hande; Yılmaz, Levent (Informa UK Limited, 2006-01-01) Carpet printing wastewater (CPW) was spiked with metal-complex dyes at concentrations of 10 and 30 mg/L to investigate the effect of feed color on separation performance of nanofiltration (NF). The rejection was excellent; 98-100% for color and COD under all spiking conditions. Although the flux decline increased with increasing dye concentration, the concentration polarization was the main cause of the flux decline. The effect of surfactants on NF separation performance was also investigated by preparing s...
Reclamation of printing effluents of a carpet manufacturing industry by membrane processes Capar, G; Yetiş, Ülkü; Yılmaz, Levent (Elsevier BV, 2006-06-01) The effluent from the print dying process of a carpet manufacturing industry was subjected to nanotiltration (NF) and ultrafiltration (UF) processes aiming at water reuse. Three alternatives were adopted; (i) NF, (ii) loose UF (MWCO 20,000 Da) followed by NF and (iii) tight UF (MWCO 1000 Da) followed by NE The separation performances and flux decline levels were compared for the detemination of the best process. Printing effluent was chemically precipitated using alum and fed to a lab-scale plate-and-frame ...
Treatment of waste pickling liquors: Process synthesis and economic analysis Ozdemir, T; Oztin, C; Kincal, NS (Informa UK Limited, 2006-05-01) An economic analysis was carried out for three different recycle/recovery options for waste pickling liquors from hydrochloric acid pickling baths in an existing small-mid scale plant presently neutralizing and discarding waste pickling liquors. The analysis was based on process synthesis and design, which were completed by using real plant data along with some experimental work. Three basic schemes were studied: the addition of metallic iron to convert unused hydrochloric acid to ferrous chloride recovery ...
Predicting drying behavior of spaghetti in a continuous industrial dryer with the models determined in a lab scale batch system Kucuk, R; Ozilgen, M (Wiley, 1997-08-01) In the first stage of this study experimental data were obtained by using a lab scale batch type dryer, operating under various constant temperature/constant relative humidity combinations; then a mathematical model was determined for the effective diffusivity of moisture in spaghetti. In the second stage of the study the model obtained in the lab scale batch type dryer was used to calculate the moisture content of the spaghetti leaving continuous industrial scale dryer, and its success was tested by compar...
