Today BioLargo published an important peer-reviewed article confirming that its innovative water treatment technology, the Advanced Oxidation System (AOS), generates highly energetic iodine molecules. The article establishes the foundational scientific principles about why the AOS is a powerful, efficient, and novel water treatment technology.

The BioLargo AOS, which is currently deployed in a demonstration pilot project at a municipal wastewater treatment plant, is a ground-breaking water treatment platform that provides rapid and effective disinfection and concurrent organics removal while consuming less electricity than other common treatment technologies. The AOS has previously been shown in bench-scale and pilot-scale studies to exhibit greater water disinfection and decontamination performance than would be expected in similar water treatment technologies. This spurred BioLargo scientists and academic collaborators to elucidate the exact electrochemical mechanisms of the AOS in this study.

The paper, published in the American Chemical Society’s journal ES&T Water, examines the mechanism by which the BioLargo AOS produces such rapid and effective disinfection performance relative to past electrochemical water treatment technologies. The study used the Canadian Light Source particle accelerator to perform advanced measurements of the chemical reactions that occur inside the AOS during operation. This technique revealed that the AOS generates highly oxidized iodine molecules that the researchers concluded are likely responsible for the technology’s elevated disinfection efficacy. These special iodine molecules were only present inside the active layers of the AOS and were neutralized before water flowed out of the AOS.

Dr. Richard Smith, President of BioLargo Water commented, “Our AOS technology is a technical leap forward in advanced water treatment. This study is integral in showing why the technology produces such high performance while consuming so little energy.”
