TL;DR: In this article, a new vapor-liquid-solid three-phase circulating fluidized bed evaporator was developed by adding solid particles to the boiling liquid in order to enhance heat transfer and solve the fouling problems in boiling processes.
Abstract: In order to enhance heat transfer and solve the fouling problems in boiling processes, a new vapor–liquid–solid three-phase circulating fluidized bed evaporator was developed by adding solid particles to the boiling liquid In this paper, the experimental studies on the performances of this evaporator—such as heat transfer, pressure drop, fouling prevention and removal—power consumption of recycle pump were carried out Based on the analysis of the heat transfer characters of these three-phase flow boiling experiment, a mathematical model for predicting the flow boiling heat transfer coefficients of this evaporator is proposed The predicted results of the flow boiling heat transfer coefficients agree well with the experimental data The quality of NaCl product obtained in this evaporator achieves the state standard of the People's Republic of China

TL;DR: In this paper, the authors reviewed and analyzed more than 300 scientific publications to provide an overview of the most recent development of MBR technology for treatment of industrial wastewaters (e.g., food processing, pulp and paper, textile, tannery, landfill leachate).
Abstract: Membrane bioreactor (MBR) technology has been extensively employed for various industrial wastewater treatments due to its distinct advantages over conventional technologies. To provide present state and development trends of MBR technology used for industrial wastewater treatments, the authors reviewed and analyzed more than 300 scientific publications. They present an overview of the most recent development of MBR technology for treatment of industrial wastewaters (e.g., food processing, pulp and paper, textile, tannery, landfill leachate, pharmaceutical, oily and petrochemical wastewaters). Moreover, they discuss the operational characteristics, fouling characteristics, fouling control strategies, and costs of MBRs in industrial wastewater treatments. Based on the present information on MBR technology, the authors discuss further research aspects of MBRs in industrial wastewater treatments.

TL;DR: Aerobic granular sludge has shown a potential for nitrogen removal, but is less competitive for the high strength organic wastewater treatments, and the future needs and limitations for aerobic granular technology are discussed.
Abstract: Aerobic granular sludge can be classified as a type of self-immobilized microbial consortium, consisting mainly of aerobic and facultative bacteria and is distinct from anaerobic granular methanogenic sludge. Aerobic granular technology has been proposed as a promising technology for wastewater treatment, but is not yet established as a large-scale application. Aerobic granules have been cultured mainly in sequenced batch reactors (SBR) under hydraulic selection pressure. The factors influencing aerobic granulation, granulation mechanisms, microbial communities and the potential applications for the treatment of various wastewaters have been studied comprehensively on the laboratory-scale. Aerobic granular sludge has shown a potential for nitrogen removal, but is less competitive for the high strength organic wastewater treatments. This technology has been developed from the laboratory-scale to pilot scale applications, but with limited and unpublished full-scale applications for municipal wastewater treatment. The future needs and limitations for aerobic granular technology are discussed.
