Monitoring and analysis of the energy cost of an MBR

Optimizing aeration rates for minimizing membrane fouling and its effect on sludge characteristics in a moving bed membrane bioreactor

“…Aeration rates in MBR systems are based on previous data and normally recommended by the membrane supplier [5,6]. Aeration comprises almost 50% of the total energy requirements of MBR operation [7]; therefore, it is very important to optimize aeration rate in MBR processes.…”

Investigation of the effects of membrane fouling control strategies with the integrated membrane bioreactor model

“…The advantages of MBRs are well-known, which include the reduced footprint and sludge production through maintaining a high biomass concentration in the bioreactor [1][2][3][4][5]. However, the MBR technology is more costly in capital and operating costs than conventional activated sludge processes (CASPs) [6][7][8]. The most significant expenditure component of operating MBRs is the energy requirement [3].…”

Evaluating the performance of activated sludge ammonia oxidizing bacteria in a lab-scale alternating hypoxic/oxic membrane bioreactor

“…The aeration accounts to approximately 50% of the overall energy expenditure in MBR operation [3]. This most likely explains why a number of comprehensive studies dealing with aeration have been conducted in the past few years to reduce energy demand in MBR [4][5][6].…”
