  • Does different backwash scheme affect membrane penetrability in MBR plants?
  • Effect of different backwash (BW) scheme (i.e., different BW duration and temperature), as a main hydraulic membrane cleaning method, on a fouled membrane (same hollow fiber membranes) in MBR plants treating municipal wastewater was investigated. Particularly, effect of them on a TMP drop and the membrane penetrability increase.
  • What are MBR plants?
  • MBR plants are created by integrating the biological process with membrane filtration which possesses numerous benefits if compared with conventional methods such as activated sludge; MBR is widely used for municipal and industrial wastewater treatment.
  • When was MBR used in wastewater treatment?
  • MBRs have been widely advanced in municipal and industrial wastewater treatment [3, 4, 5]. The application of MBR in wastewater treatment was first reported in 1969, when an ultrafiltration membrane was utilized for the separation of the activated sludge to produce high-quality secondary-treated effluent .
  • Why do MBR plants use ultrafiltration membranes?
  • This is because if the membrane pore size and particle size become the same then clogging occurs and results in a decrease in the permeate flux. In MBR plants, usually ultrafiltration membranes are in favor because generally, the smallest size of the activated sludge is around sub-micrometer which is close to microfiltration membranes .
