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
