The Challenge
The Challenge:• Reducing targeted nutrients cost-effectively
• Increasing desire to move away from traditional
metal salt additions
• Developing solutions that scale with future
needs
Our Approach:• Sustainable, advanced resource recovery
• U.S. Patent 8,101,080
• View algae as a process, not a product
Benefits:• Best-in-Class nutrient recovery
• Zero chemical sludge produced
• Recycles C02
and releases O2

Economics
A 5MGD facility moving from a TP of 1.0mg/L to 0.5mg/L would:
– Remove > 7,600 pounds / phosphorus per year
– Remove > 50,000 pounds / nitrogen per year
– Add >1,200,000 pounds / oxygen per year into the receiving body
– Consume >1,600,000 pounds / CO2
per year
– Produce >760,000 pounds of biomass per year
– Cost approximately $0.43 / 1000 gallon (20 year Total Cost of Ownership)
– Cost ~$100/pound of phosphorus removed
– Cost ~$13/pound of (nitrogen and phosphorus removed)
– Cost the average household $3.21/month (capex and Opex)
– Cost the average household $0.95/month for annual O&M
