The Case for Removing Post-Disinfection from MBR Treatment

This paper shares data collected over five years from more than 10 MBR facilities in North America, Europe and Australia to offer a benchmark of the long term ability of full scale MBR installations to provide high levels of microbial removal. The facilities that were sampled all used ZeeWeed UF membranes, selected to include varying membrane ages, hydraulic capacity and geographical location. Over 2,700 data points were collected for total coliforms, fecal coliforms, and E. coli bacteria in both the raw wastewater and MBR permeate to provide an aggregate view of MBR disinfection efficacy.
