BIOLARGO’s AOS FILTER Converts a filter into a powerful reactor to manage and remove harmful contaminants

A SCALABLE WATER TECHNOLOGY

The BioLargo Advanced Oxidation System (AOS) Filter

HOW IT WORKS

“Unprecedented Results”*Professor Lynn McMullen, University

of Alberta

Carbon Iodine Chemistry Electricity *Extremely HighOxidation Potential

Unique Value propositionWhen compared to all known competing technologies, BioLargo’s AOS filter has been proven in hundreds of lab tests at the University of Alberta to be:

9

up to 100x more effective

1/20th the cost 10x faster

Aos Filter: highest impact Disinfection: +7 log kill (99.99999%) Removes Soluble Organics Manages Bacterial BioFilm Extreme Power Efficiency Flow-Rate Efficiency (continuous) Practical application for recapture of

waste stream contaminants Low Cost (Cap X + Op X)

STUDY RESULTS

AOS - Development Cycle (targets)

Generation I - Point of Flow Modular System• Disinfection (Commercial Prototype August 2016) • Soluble Organics Destruction / Removal (Optimized: 2017)• Extraction / Recovery of Valuable Components of Waste

Stream (Optimized: 2017 – 2018)

Generation II - Fluidized Bed System • High Volume Capability• Extremely Low Reactor Cost• Gravity vs. Pump Driven System• Breakthrough Carbon Credit Delivery • Breakthrough Power Delivery System Drives AOS

Reactions12

Low Cost & Low Power Generation I

Low Cap-X• Equivalent to Carbon System• < ½ the Cap Ex of an Ozone or UV System

Low Power (Op-X)• The incremental addition of energy to generate

the extremely high oxidation potential is deminimis to achieve high level disinfection

• The addition of energy to generate the extremely high oxidation potential to destroy soluble organics is estimated at less than 1/20th the cost of the nearest technical competitor
