Eliminating pollution in wastewater from poultry processing and more.


Our corner of the water market — chicken wastewater.
Chicken processors use a lot of water — and spend $246M a year to treat it.1 Our product allows poultry wastewater to be cleaned, recycled and reused on-site at lower capital and maintenance cost than many existing technologies.

We’re not starting at ground zero.
Since 2015, almost $4M has been invested on research and development to create the Advanced Oxidation System — AOS™ — a new and disruptive solution for wastewater treatment. Funding has been primarily through industry and government partnerships.

Our system costs less and does more.
Compared to many competing technologies, AOS: (1) costs less to install & operate; (2) allows on-site water recycling and reuse, or safe discharge; (3) eliminates contaminants and pollutants existing systems can’t; (4) does it all in one system, rather than requiring multiple technologies; and, (5) requires less space.

It’s working.
Modular, compact and cost-effective, AOS succeeds where many existing technologies can't. In 2019, at a poultry plant pilot, AOS-treated water met all local re-use and discharge standards, with guidelines provided by the United States Department of Agriculture (USDA) and Environmental Protection Agency (EPA).

Smart people. Powerful backing.

Smart people. Powerful backing.
The BioLargo Water team of Ph.D. scientists and engineers has created a breakthrough product. Now — with the technical support, marketing & finance resources, and more, of our parent company BioLargo, Inc. — AOS stands poised to enter the $246M poultry wastewater market.

Chickens are just the start.
The “gateway market” for AOS is poultry processing, a challenging market underserved by large consolidated water treatment companies. If we can clean up poultry wastewater more effectively and more affordably, many other markets – some of which we have also piloted – may become open to us.

Advanced Oxidation System


  • Saves water through on-site wastewater recycling and reuse.
  • Eliminates viruses, bacteria, antibiotics, pharmaceuticals and micropollutants.
  • Lowers contaminant load for the safe return of water into waterways.


Wastewater treatment, decontamination and discharge is a critical challenge for industries across the board. The poultry industry is particularly challenging.

About nine billion chickens are processed in the U.S. every year, creating more than 60 billion gallons of highly contaminated wastewater2, often with dire consequences: polluting local waterways and sources of drinking water with viruses, bacteria, antibiotics and other contaminants harmful to human health and the environment.

Existing water treatment technologies are too often not affordable and can often be too big for many industrial facilities. Operators need portable, smaller and modular systems that don’t upset their operations. This is true for small facilities as well as major operations.

Poultry wastewater is highly contaminated and difficult to treat in a cost-effective, comprehensive way.

Advanced Oxidation System — AOS™ Invented, developed and proven by BioLargo Water, Inc. 

Portable, on-site and modular, AOS costs less and does more, with a smaller footprint. AOS replaces standard systems currently in use — including chlorination, ozonation, and ultraviolet (UV) radiation — by employing disruptive oxidation technology that:

  • allows farms to recycle and reuse water on-site
  • uses less power and energy
  • is cheaper to purchase and operate
  • is more effective in removing pollution & contaminants
  • saves on water use & can reduce clean-water costs by two-thirds

Following the successful AOS pilot at Sunworks Farms in Alberta, Canada, BioLargo Water announced their first full-scale commercial trial in September 2019 to manage and treat Sunworks' water and wastewater farm-wide, marking a pivotal moment in the commercialization of BioLargo's proprietary technology.

“Their technology clearly works, and their team is a pleasure to work with. We believe that the AOS will enable producers like us to manage water and wastewater in the most environmentally sensitive and economical way possible.

We look forward to working hand-in-hand with their team to establish their technology as part of a new benchmark for environmental stewardship in water conservation in the North American livestock industry.”

— Ron and Sheila Hamilton, owners of Sunworks Farm



Cost — Testing has shown that the AOS will provide robust, reliable water treatment at a lower operating cost (OPEX) than incumbent treatment technologies, and at lower capital cost (CAPEX) due to the simple and ubiquitous materials required to build the AOS.

AOS Competitive Advantages

Capabilities — In existing scale-up and laboratory trials, the AOS inactivates waterborne micro-organisms including Escherichia coli, Salmonella, and bacteriophage MS2 more cost-efficiently and with substantially lower energy requirements compared to conventional technologies. The AOS system shows tremendous capability to remove waterborne pollutants including poly-aromatic hydrocarbons (PAHs), naphthenic acids, and micro-pollutants (i.e., pharmaceuticals and antibiotics) which conventional technologies are inefficient at treating.


BioLargo Water will launch its technology into the poultry industry, a $246 million market. The industry is under increased pressure to better treat its wastewater. Rising water treatment costs have also created an incentive for poultry facilities to recycle and reuse water.

This makes poultry processing ideal as a “gateway market” to demonstrate AOS' economic and technical superiority versus many incumbent existing technologies. After the company commercializes AOS in the poultry processing market, its target markets will be stormwater (where we've conducted a capture and reuse pilot); food & beverage (including a successful AOS commercial field pilot at a micro-brewery); plus more work in agriculture, petrochemical/oil & gas, and the huge municipal wastewater facilities market.

Total Addressable Markets

BioLargo intends to roll-out AOS with an unparalleled, no-risk proposition for industrial wastewater needs. For our initial customers, BioLargo Water, Inc. will pay to build and install the AOS system and user will pay nothing — zero — until performance and cost savings are proven. We believe this “No Risk” model will greatly accelerate our entry and expansion in the market.



Financial Projections
These values for AOS revenues are within BioLargo Water's first four target markets: agriculture, food & beverage, stormwater and municipal.
