Presentation Highlights
•  Inoculum Production
•  ARID Raceway Advances and
Improvements
•  CAM Infinὶ PBR
•  Improving Nutrient Uptake
•  Alternative Nutrient Sources
Inoculum
Production
•  Industrial Plankton PBRs
•  100L, 1000L, 2500L Sizes
•  Upscale readily to larger ponds/PBRs
•  Fully automated
•  Cleaning, harvesting, sterilization, media
make-up
•  Automation reduces the need for
expensive labor. Units can pay for
themselves in less then a two years
•  Used in research, aquaculture, and
inoculum production
ARID – Algae Raceway Integrated
Design
•  Raceway design with large canal
•  Large canal conserves the heat from the day
•  When the sun goes down
• 
• 
• 
• 
• 
Photosynthesis stops
Air bags deflate
Large canal collects algae culture
Air sparger helps circulate algae
Heat is conserved
•  Sun comes up
• 
• 
• 
• 
Air bags inflate
Culture is pumped into shallow basin
Photosynthesis starts
Growth begins immediately without needing to
reheat
ARID – Algae Raceway Integrated
Design
•  Consistent temperature profile
•  Large canal conserves the heat from the day
•  Increased growth kinetics
•  Proprietary methodology allows for extra cell
replication
•  Increased Turbidity
•  Increased growth kinetics allows for overall cell
density to increase and create more biomass
ARID – Algae Raceway Integrated
Design
•  Recent Advancements
•  100% Solar powered, battery power
instruments and sparger at night and on
cloudy days
•  Low cost pumps and other materials
•  Food grade compatibility available
•  Other key benefits
•  Zero grid energy consumption
•  Significantly higher energy productivity
•  Low CAPEX and low OPEX
CAM Inifinὶ
PBR
•  Key Features:
• 
• 
• 
• 
• 
• 
• 
• 
• 
Low cost
No shear stress
Proprietary water mover technology
Integrated or stand alone system
Can operate off solar power
Limited ground improvement required
Controlled CO2 and DO
Integrated temperature control option
Cloud based internet accessible controls and
data
•  Easy installation , completely modular
CAM Inifinὶ
PBR
•  Low cost, UV resistant bags
•  Diameters available from 6” to 12”
•  Scalable
•  Volume up to 800m3/acre
•  Now in operation with both micro and
macro algae strains
•  Ideal for creating low cost closed loop and
hybrid system environments
•  Uses all Food grade components
Improving Nutrient
Uptake
Finding Low Cost Nutrient solutions for Commercial Growth
Preparing typical nutrient solutions can be time consuming
Possibilities of two compounds forming a third insoluble
compound that can precipitate out of the nutrient solution.
American Algae Nutrients has developed two new algae
nutrient formulas that are 100% soluble up to pH 9 levels
All the essential macro and micro nutrients elements
Separate formulas for freshwater and marine algae
16 essential nutrient elements (including all macro and micro
nutrient elements for ideal algae biomass growth)
Less expensive then typical BG11 and similar media
Alternative Nutrient
Sources
•  Conventional nutrient sources are expensive
•  Phosphorus “peak” is coming
•  Potential solutions
•  Conservation of current supply
•  Salt recovery from large bodies of water
•  Recycle nutrients from other industries
•  Conversion of waste products to nutrients
•  Potentially will mitigate the “peak”
Alternative Nutrient
Sources
•  HyTek Bio’s Algae Biomass Nutrient
•  Raw chicken manure converted to clear, odorless liquid
•  Liquid nutrient contains Nitrogen (Ammonia) and
Phosphorus
•  Proprietary process removes contaminants
•  Contains 85 mg/L Nitrogen (as Ammonium)
•  Contains 50 mg/L Phosphorus
•  Production cost is extremely inexpensive
Summar
y
•  Low costs are imperative for future of this industry
•  Reliable options for cultivation are available today
•  Algae will eventually need to become a commodity
crop for long term success.
•  Nutrients are expensive and can be acquired from
unconventional sources
•  Everything we need to make algae viable for large
scale cultivation is available today
