Peer-reviewed scientific paper confirms safety of water treated by Advanced Oxidation System
BioLargo says peer-reviewed scientific paper confirms safety of water treated by its Advanced Oxidation System
The study shows the company's Advanced Oxidation System (AOS) generates less disinfection by-products than common wastewater treatment technologies
Dr Greg Goss, the paper's author described BioLargo's AOS as 'a major technical breakthrough for the treatment of micropollutants'
BioLargo Inc (OTCQB:BLGO) has announced the publication of a peer-reviewed scientific paper that confirms the safety of water treated by its Advanced Oxidation System (AOS), an energy-efficient industrial water disinfection technology.
The Westminster, California-based company said the paper, which focused on quantifying the disinfection by-products generated by the AOS, represents a “critical milestone” in the commercialization of the company’s “innovative” water treatment technology.
BioLargo noted that its ground-breaking AOS technology provides high-level disinfection and consumes less electricity than competing technologies such as UV and ozone-based systems. Significantly, the AOS removes pharmaceutical micropollutants from water to provide added value across diverse water treatment applications, including municipal wastewater treatment.

The study, led by the laboratory of Dr Susana Kimura-Hara at the University of Calgary, assessed the disinfection by-products (DBPs) generated by the company’s AOS. “The paper concluded that the levels of DBPs generated by the AOS were comparable to those found in ordinary tap water,” said the company.
As all water treatment technologies generate DBPs, the quantity and relative safety of disinfection byproducts generated by a given water treatment technology is an important consideration for customers deciding which technology to select for their needs, BioLargo noted.
The results of this study, therefore, represent a key milestone for the AOS, which has a municipal wastewater treatment demonstration pilot underway near Montréal, Québec, and is currently being readied for commercial trials, it added.
The study corroborates the results of another peer-reviewed paper published earlier this year that showed the AOS does not increase the toxicity of treated water. Notably, that study also showed the AOS to be capable of negating the negative effects of two hard-to-treat micropollutants.
Dr Greg Goss, the new paper's author described the AOS as "a major technical breakthrough for the treatment of micropollutants."
The BioLargo Water Division has designed the Advanced Oxidation System, to eliminate waterborne pathogens and recalcitrant contaminants with better energy-efficiency and lower operational costs than current technologies.
The company is also developing its Aqueous Electrostatic Concentrator (AEC), which eliminates a toxic soup of chemicals from water. The chemicals, resistant to breaking down in the environment, are known as per and fluoroalkyl substances, or PFAS. According to media reports, some have been linked to cancers, liver damage, low birth weight and other health problems.
