The membrane bioreactor (MBR) is one application of membrane technology in wastewater treatment. Submerged MBRs, in which
membranes are directly submerged in the aeration tank, have received significant attention because of their several advantages,
including improved and more reliable effluent quality. In this study, the performance of hollow fiber micro filtration membranes
immersed in a bioreactor for removal of chemical oxygen demand (COD), total suspended solids (TSS) and turbidity from municipal
wastewater containing industrial wastewater was studied at different hydraulic retention times. The results demonstrate high
treatment efficiencies for COD, TSS and turbidity, and the concentrations of these pollutants under all operating conditions
were reduced to as low as 9mg/L, 1mg/L and 0.3NTU, respectively. Therefore, this technology may be regarded as a promising
treatment method for various applications in wastewater effluent reuse.

    ABSTRACT: Treatment of caffeine wastewater with high COD, high nitrogen content and poor biodegradability was investigated with a sequential anaerobic baffled reactor (ABR) /membrane bioreactor (MBR) system. The effect of organic loading rate (OLR) and temperature on the performance of the system was examined. The experimental results show that the COD removal efficiency decreases with the increasing OLR for ABR, the ammonia nitrogen levels raise greatly after the ABR process and decrease to desired levels after the MBR process. Fed at an OLR of 2.23 kgCOD/m 3 d, the system works efficiently with an HRT of 27.5 h at 37�� , and the COD removal of 71.3% and 92.7% are achieved for ABR and MBR, respectively, and the removal of ammonia nitrogen is 91.7% in MBR with the effluent level of 11.49 mg/L. The optimum temperature for the ABR is 37�� , close to the mesophilic temperature, however, the MBR performs well in a wider temperature range of 19-37�� . The nitrogen compounds are con verted to ammonia nitrogen in ABR and to nitrite and nitrate in MBR, thus accomplishing the removal. Therefore, the sequential ABR/MBR system may be regarded as a promising alternative for the treatment of caffeine wastewater.

    ABSTRACT: Background: Anaerobic treatment methods are more suitable for the treatment of concentrated wastewater streams, offer lower operating costs, the production of usable biogas product. The aim of this study was to investigate the per-formance of an Anaerobic Fluidized Bed Reactor (AFBR)-Aerobic Moving Bed Bio Reactor (MBBR) in series ar-rangement to treat Currant wastewater. Methods: The bed materials of AFBR were cylindrical particles made of PVC with a diameter of 2-2.3 mm, particle density of 1250 kg/m3.The volume of all bed materials was 1.7 liter which expanded to 2.46 liters in fluidized situa-tion. In MBBR, support media was composed of 1.5 liters Bee-Cell 2000 having porosity of 87% and specific surface area of 650m2/m3. Results: When system operated at 35 ºC, chemical oxygen demand (COD) removal efficiencies were achieved to 98% and 81.6% for organic loading rates (OLR) of 9.4 and 24.2 g COD/l.d, and hydraulic retention times (HRT) of 48 and 18 h, in average COD concentration feeding of 18.4 g/l, respectively. Conclusion: The contribution of AFBR in total COD removal efficiency at an organic loading rate (OLR) of 9.4 g COD/l.d was 95%, and gradually decreased to 76.5% in OLR of 24.2 g COD/l.d. Also with increasing in organic loading rate the contribution of aerobic reactor in removing COD gradually decreased. In this system, the anaerobic reactor played the most important role in the removal of COD, and the aerobic MBBR was actually needed to polish the anaerobic treated wastewater.

    ABSTRACT: The amount of wastewater characteristics loading is one of the main parameters in the design of wastewater collection and treatment systems. The generation per capita per day (GPCD) of wastewater characteristics was estimated by analyzing the monthly data of nine wastewater treatment plants in Tehran, capital city of Iran. GPCD values were calculated from measured collected wastewater flow, the population and concentration data. The results indicated the values of 32.96 ± 1.91, 49.25 ± 2.49, 37.31 ± 2.44, 6.77 ± 0.53, 1.96 ± 0.11, 92.23 ± 5.68, 2.07 ± 0.39 and 128.96 ± 6.69 g/d.cap of GPCD for BOD5, COD, TSS, TKN, P, TDS, ON and TS, respectively, for Tehran’s wastewater. The per capita estimated for the wastewater production and treatment were determined to be 186.06 ± 7.85 and 136.72 ± 5.43 L/d.cap, respectively. It is estimated that about 504 m3/d and 346 m3/d of sludge, will be produced and waste as excrement raw sludge, respectively, in Tehran. Simple regression models were presented the relationships such as the change of collected and treated wastewater with population and changes of GPCD parameters with each other. It was revealed that the Tehran’s wastewater may be classified as highly degradable, but during recent decades its Biodegradability Index (BI) has been reduced up to 15%. The new suggested revised per capita parameters can be used for design purposes in Tehran, and possibly, in areas with similar characteristics, substituting the classical values obtained from foreign textbooks. These values could help in designing more accurate treatment systems and may lower the required capacity for the treatment of wastewater up to 40% in Tehran.
