Utilizing MBRs in Potable Reuse – Best Practices

Utilizing MBRs in Potable Reuse – Best Practices

on-demand webinar recorded March 2023
Membrane Bioreactors (MBRs) have been used since the early 2000s in North America as a conventional wastewater treatment process that combines the benefits of a secondary clarifier and a tertiary filter. More recently, MBRs have been considered for potable reuse schemes in place of a conventional secondary clarifier followed by a UF membrane system because of their advantages in footprint and efficiency. When an MBR is implemented for potable reuse, special considerations for design and operation need to be considered.
