The challenge: • Reducing targeted nutrients in a cost effective manner

Our solution: • View algae as a process…not a product • Sustainable, advanced nutrient recovery

o US Patent 8,101,080

The benefits: • Best in Class performance • No chemical sludge produced • Sustainable • Multi-generational, single technology
