The very first AOS devices bore little resemblance to today’s AOS. Its job was to demonstrate the principle that advanced carbon materials combined with iodine electrochemistry would result in rapid disinfection and decontamination.
The AOS’ Adolescent Years
The next step in AOS development was a big one – our first pre-commercial prototype. The purpose of this was to demonstrate that the AOS could be scaled to a size relevant to water treatment in a real, albeit small, commercial setting. It also needed to be equipped with on-board sensor systems that could measure water quality parameters, flow rate, and pressure. To accomplish this, we partnered with an incredibly talented team of sensor developers at the Northern Alberta Institute of Technology’s (NAIT) Centre for Sensors and System Integration (CSSI) in Edmonton. With NAIT, we built the first Alpha Prototype, complete with state-of-the-art sensors, which we showcased at our technical symposium in August of 2016.
Soon after this, the BioLargo Water team began to work on a new iteration of the AOS – the “Spiral AOS”. This prototype is designed for interior water treatment applications where space is more of a concern and where a compact water treatment platform is preferable. We showcased the AOS late last year on our blog, and you can learn more about it there! The conventional “Stacked” AOS is still used for applications where space is a less important consideration (for example, at a poultry farm). Thanks in part to the modularity of the Spiral design AOS, the technology is now scalable to nearly any required flowrate by adding increasing the number of AOS reactors in a treatment train.
All of this work could never have been possible without the generous support of government funding agencies like NRC-IRAP, NSERC, Alberta Innovates, and Southern California’s MWD-ICP program. Grants from these organizations helped pay for salaries, equipment, consumables, lab space, office space, and important research collaborations. All in, BioLargo Water has received more than 60 grants to fund its R&D work on the AOS thus far.
