BioLargo Reveals Scaled Up Commercial Design for AOS Water Treatment Technology

Manufacturing is in process

Westminster, CA – March 17, 2020 – BioLargo, Inc. (OTCQB:BLGO), developer of sustainable technologies and a full-service environmental engineering company, announced that it has designed and is manufacturing a scaled up commercial prototype of its proprietary Advanced Oxidation System (AOS) that is capable of processing 500 gallons of water per minute (“GPM”), a volume commensurate with the flowrate requirements of many commercial applications.

The new design utilizes the Spiral AOS geometry in order to achieve greater flowrate capacity without sacrificing size, and is expected to be the most energy-efficient model of the AOS technology to-date. This new design is modular and easily scalable by increasing or decreasing the number of AOS spiral reactors (the long horizontal cylinders seen here), each of which is expected to be capable of 125 GPM.

The 500 GPM AOS unit (seen in Figure 1) is suitable for use in many commercial settings, including poultry processing and the stormwater treatment and water reuse market, where the company is currently pursuing commercial piloting opportunities, as well as secondary markets which include stormwater, food & beverage, industrial and oil & gas, agriculture, and municipal.

Dr. Richard Smith, President of Biolargo Water remarked, “BioLargo’s engineering team has made it possible to accelerate the transformation of the AOS from a small, bench-scale unit to a pilot unit, and now to a commercially viable large-scale water treatment system. We are fortunate to have access to those experienced engineers.”

BioLargo Engineering President Randall Moore, a 20+ year veteran in delivering environmental engineering services, commented, “Producing a 500 GPM AOS system is the next requisite step in the commercialization of the AOS technology. Moving to this larger scale (approximately one cubic foot per second) immediately changes the AOS from a research-focused prototype into a viable, commercial water disinfection option for multiple industries. As a modular system, much higher flow rates than 500 GPM are possible. A ten by ten array of 500 GPM AOS units could effectively disinfect 50,000 GPM, needed for large scale applications such as municipal water treatment plants. This important scale-up step brings with it a world of opportunity.”

BioLargo, Inc. President & CEO Dennis P. Calvert commented, “This a momentous day for BioLargo Water and the AOS technology as it puts behind us the question of whether we can scale the AOS technology to meet the high volume needs of the very large water treatment market. It also highlights the collaborative design and manufacturing effort between BioLargo Water and our engineering team at BLEST.”
