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 performance of an Anaerobic Fluidized Bed Reactor (AFBR)-Aerobic Moving Bed Bio Reactor (MBBR) in series arrangement to treat Currant wastewater. METHODS The bed materia...

Biomass accumulation is a major obstacle for long-term, stable operation of biotrickling filters treating high loadings of volatile organic compounds (VOCs). Clogging reduces pollutant removal and increases the pressure drop in biotrickling filters. Several options exist to remove excess biomass or to slow down the accumulation rate, but so far none has succeeded in combining a high VOC removal...

In a novel dual bed reactor Fischer-Tropsch synthesis was studied by using two diffrent cobalt catalysts. An alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a Rutenuim promoted cobalt catalyst in the second bed. The activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed r...

A University of Cape Town (UCT) pilot plant combining both membrane bioreactor (MBR) and moving bed biofilm reactor (MBBR) technology was monitored. Three experimental Phases were carried out by varying the mixed liquor sludge retention time (SRT) (indefinite, 30 and 15 days, respectively). The system performance has been investigated during experiments in terms of: organic carbon, nitrogen and...

Nghiên cứu nhằm đánh giá hiệu quả xử lý nước thải sinh hoạt bể phản ứng thể di động (Moving bed biofilm reactor - MBBR) kết hợp với cột màng lọc tự chế ở những thời gian lưu khác nhau. Bể MBBR có tích 45,54 L chứa 40% K3, và quy mô phòng thí nghiệm được sử dụng trong nghiên cứu. Kết cho thấy tải nạp vào là 0,47 kg BOD5/m3/ngày, 0,79 m3/m2/ngày qua màng, 6 giờ, đầu ra đã đạt QCVN 14:2008/BTNMT (...
