Lessons Learned from Start-up of the 10 MGD Membrane Bioreactor at Irvine Ranch Water District.

This large-scale membrane bioreactor (MBR) project by a progressive water agency in semi-arid Southern California provides a useful model for others to emulate. The project advances the use of the MBR process and provides for expansion of recycled water to new uses. This paper and presentation show how a variety of participants, many of whom are AWWA and AMTA members, collaborated to deliver a successful membrane-based water treatment production facility.
