Membrane bioreactor (MBR)

Laboratory scale experiments were conducted to investigate the removal mechanisms of trace organic contaminants using a submerged MBR system. The system was equipped with a Zenon ZW-1 membrane module. Bisphenol A and sulfamethoxazole were selected as model trace organics representing endocrine disru

The paper presents the applicability of a membrane coupled anaerobic baffled reactor (ABR) for low-cost, waterborne sanitation to those communities with limited access to basic sanitation and are inappropriate for on-site, dry sanitation systems. This represents a challenge as anaerobic MBRs must be

A market survey of the European MBR industry was performed, contacting 33 suppliers or retailers of MBR filtration systems and/or MBR plant constructors. We identified MBR plants constructed up to 2005, and about 300 references of industrial applications (> 20 m3/d) and about 100 municipal wastewate

Membrane bioreactors (MBRs) can replace the activated sludge process and the final clarification step in municipal wastewater treatment. The combination of biological degradation with membrane filtration allows for high reduction of chemical oxygen demand (COD), biochemical oxygen demand (BOD), and

Pilot- and full-scale experiments were performed to elucidate the feasibility of using a modified cationic polymer for capital and operational cost savings. This membrane performance enhancing product is referred to as MPE50TM. Since the low flux caused by low water temperature is one of the most im

Three identical Biosep® membrane bioreactors were operated at different sludge retention times of 8, 15 and 40 d in order to treat municipal wastewater. The design of this process is an aerated activated sludge reactor and a submerged microfiltration hollow-fibre membrane. The objective of this stud

A contributor to success in managing membrane operations is to be able to identify suitable engineering design approaches to slow down the membrane fouling rate. Two such approaches were discussed in this study, namely: (1) off- site chemical and mechanical cleaning, and (2) air scouring. A longer s

Enhanced biological phosphorous (Bio-P) removal process was adapted to membrane bioreactor (MBR). One bench-scale pilot plant (BSP, 200–250 L) and two medium-scale pilot plants (2//MSP, 1000–3000 L each) were operated under several configurations, including pre-denitrification and post-denitrificati

A landfill leachate treatment plant (LLTP) in Korea was retrofitted to improve treatment efficiency by using integrated membrane process that is composed of membrane bioreactor (MBR) and reverse osmosis (RO) process. In general, proper treatment of landfill leachate is difficult for its refractory c
