PROJECT OBJECTIVES
1 . Proof of concept using tertiary membrane filtration for producing
Title 22 recycled water with Central San's secondary effluent
2. Prepare business case evaluation comparing a tertiary
membrane filtration alternative with granular media filtration
(current technology used by Central San)
3. Leverage pilot opportunity to evaluate other benefits of using
membrane filtration for future recycled water projects
4. Preliminary evaluation of using pilot using membrane for MBR
upstream of the filter and RO downstream in planning for the
water exchange project
Membrane Bioreactor(MBR) Reverse Osmosis(RO)
