WESTMINSTER, CA / ACCESSWIRE / January 4, 2021 / BioLargo, Inc. (OTCQB:BLGO), developer of cutting-edge environmental technologies and a full-service engineering company, announced the publication of a peer-reviewed scientific paper in the Journal of Environmental Management confirming that the energy-efficient and cost-effective Advanced Oxidation System (AOS) water disinfection system also safely removes certain micropollutants from municipal wastewater. The paper concludes that the AOS is “a promising and environmentally friendly technology for wastewater treatment, remediation, and management”, highlighting the additional value the AOS can provide customers by addressing an important and poorly served technical need in the water industry. Dr. Greg Goss, in the Faculty of Science at the University of Alberta and the researcher who led the study, commented “The AOS is a major technological breakthrough for the treatment of micropollutants.”
Micropollutants are widespread synthetic chemicals that end up in municipal water supplies around the world. They originate from pharmaceuticals, personal care products, detergents, pesticides and more, and are linked to ecological damage and human health issues. They are distinct from other water contaminants because they are difficult and expensive to remove using conventional technologies such as UV, ozone, and biological treatment.
The need for cost-effective treatment of micropollutants in water and wastewater is well recognized in the water industry. One significant issue with municipal wastewater is the feminization of fish in the receiving environment due the presence of endocrine disrupting chemicals (EDC) such as estradiol. This paper reports that the BioLargo AOS effectively removes the EDC effects of estradiol commonly present in municipal wastewater. The other micropollutant tested in the study, benzo[a]pyrene, is regulated by the EPA pursuant to the Safe Water Drinking Act. The U.S. EPA maintains a published list of “contaminants of emerging concern” that includes a number of additional micropollutants in municipal wastewater that may cause ecological or human health impacts, but are not yet regulated. As regulatory scrutiny continues to increase surrounding micropollutants, municipalities are seeking technologies that can affordably and safely remove them from their wastewater streams to prevent surface water contamination.
BioLargo’s ground-breaking and patented Advanced Oxidation System (AOS) is a water treatment platform that provides high-level disinfection and consumes less electricity than competing technologies. The AOS’ ability to eliminate the deleterious effects of micropollutants in wastewater offers significant additional value to the municipal wastewater treatment market by providing affordable and effective micropollutant removal in addition to its primary use as an energy-efficient and cost-effective wastewater disinfection technology.
