Distribution and mass transfer of dissolved oxygen in a multi-habitat membrane bioreactor

Simultaneous ammonia and nitrate removal in an airlift reactor using poly(butylene succinate) as carbon source and biofilm carrier

“…As a result, the DO concentration was much higher in the aeration zone and surface water than the relatively lower DO value in the internal area of the PBS due to microorganisms that consumed DO to decompose organics and N-containing substances. The DO profile showed that airlift inter-loop reactor can create alternating aerobic-anoxic environments, which might benefit for simultaneous removal of TAN and nitrate (Tang et al, 2015).…”

Model-based design of a pilot circulating bed membrane bioreactor for sewage treatment

“…(4) and (5) are relevant to an air-water system. The actual V L values in the proposed bioreactor are expected to be lower than the values given in Table 1 primarily due to the non-Newtonian (pseudoplastic) nature of the mixed liquor with an apparent viscosity significantly higher than the viscosity of water or aqueous solutions (Hasar et al, 2004, Tang et al, 2015.…”

CFD simulation and optimization of membrane scouring and nitrogen removal for an airlift external circulation membrane bioreactor

“…Since 2003, this technology has been applied in more than 40 plants of wastewater treatment and reuse for public washrooms, hospitals, pharmaceutical factories and residential buildings in China (Zhang et al, 2013 alternative anoxic-oxic MBR system for nitrogen removal by replacing the aeration diffuser with paddle agitating in the aeration tank. A similar system called a multi-habitat MBR was proposed by (Tang et al, 2015. In their study, a high nitrogen removal rate was achieved due to the biodiversity and succession of the microbial community resulted from the formation of a multihabitat in a single MBR.…”
