History On Napkins
One day, on a Bullet Train somewhere in
Japan, suffering from sake and beer poisoning,
two engineers conceived of Bandon Dunes, OR
on the back of a napkin…
Ten years later, in
a hotel
somewhere in
Seattle, suffering
from tequila
poisoning they
conceived of
Canyonville, OR
on the back of
another napkin…

“Why didn’t you
recommend MBR over
SBR the first time you
upgraded our plant?”
- Ron Reibach
Director of Facilities
• March, 2008
• Changed SBR to MBR
Utilizing Existing Tanks
• Utilized Existing
Headworks
• Increased Capacity of
Peak Day from 0.45 MGD
to 0.60 MGD
• Spray Irrigation / Sub Surface
Disposal
• Biosolids Dewatering / Landfill
Disposal
• 4 FTE to 2 FTE “MBR’s are the only way to go for
Casino WWTPs.”

TOP 5 OPTIMIZATION STRATEGIES
Strategies to reduce
cost and make
competitive with SBR
Optimization
Accurately size MBR portion of
process
Don’t be fooled by apparent
complexity of system
Maximize flat sheet operating
characteristics
Take advantage of existing facilities
Get your equipment representative
to lower sales commission

TOP 5 IMPROVEMENTS
From an engineer’s
perspective numerous
system improvements were
necessary to get costs
down and to get the full
benefit of MBR and storm
flow management (peak
capabilities).
Improvements

My Top 3
recommendations that
you can take to the
bank for a more reliable,
more efficient MBR System.
Optimization
Utilize Flat Sheet Membranes
