• All Facilities Utilized Flat Plate Technology• Effluent Disposal Requirements Driving Treatment• Reuse Common Goal• 78% of Projects Design-Build• Typical Duration of Project – 8 Months • 89% of Projects were for Tribal Facilities• 67% of Projects were for Gravity Systems• Treatment Capacity of all Facilities Expandable,

Utilizing Existing Tanks• 89% of projects completed by the same contractor• Had a “Nitch” from 2002 to 2010• Constantly “Bitching” About Equipment Costs

PLANT FUN FACTS


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…

Bandon Dunes The Next One


Bandon Dunes Project Highlights

The first operational flat plate MBR in the United States Bandon Dunes is still in operation, still has the same SCADA, has no fine screens. One operator runs the plant and…four world class golf courses…

Spirit Mountain Casino Project Highlights

“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.”

- Rod Smith Lead Operator

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
