Micro Plasma Ozone Generators
As their name implies, microplasmas are plasmas (partially-ionized gases) produced within channels or cavities having microscopic dimensions. Powered electrically by integrated electrodes, these plasmas have extraordinary properties quite unlike those for macroscopic (large volume) plasmas. The principles governing conventional plasma ozone systems date back to the 1860s and rely on the formation of ozone in sparks, streamers, or arcs created in oxygen gas. Such generators are typically large, heavy, and require very high voltages.
In contrast, our microplasmas are spatially uniform “glow” plasma produced in microchannels that are generally several hundred micrometers in width and several cm in length. As shown in the drawing (above) of a single microplasma “chip,” oxygen or air is introduced at one end of an array of parallel microchannels. Plasma produced in the channels efficiently converts oxygen into ozone which then leaves the channels. The microscopic, intense plasma environment produced within the channels is ideal for the generation of ozone from oxygen or room air. Also, ozone is produced along the entire length of the microchannels, as opposed to only in the immediate vicinity of a high voltage streamer. The photograph (above) shows an end-on view of several microchannels during the production of ozone. The blue glow from each channel underscores the uniformity of microplasmas which is a key factor leading to the efficiency and small size of our ozone systems.
Microchannel plasma arrays are fabricated from thin aluminum sheets by a proprietary, patented process and are lightweight and compact. Because the microplasmas in the channels are protected by aluminum oxide, however, these arrays are robust and not sensitive to water vapor in the oxygen or air flow stream that can be lethal to conventional ozone systems. Unlike conventional ozone generators which are limited by their large size, weight and high cost of ownership, the size and weight of our microplasma reactors are a factor of ten (10x) less than the conventional system of equivalent output, which greatly reduces cost and footprint making it suitable for treating water in resource constraint environments.
Modular Design & Eco Friendly
We have developed and exhaustively tested a modular approach to ozone system design that represents a breakthrough in the industry. Modules incorporating as many as 10 microplasma chips offer an ozone generation technology that is readily scalable to accommodate the requirements of any customer. Each chip produces 2 grams of ozone per hour from an oxygen feed which is more than sufficient, for example, to disinfect 200-300 gallons of water per hour. Stacking 5 chips in a module results in an ozone production rate above 10 grams per hour.
Our water disinfection systems eliminate the use of chlorine and other toxic chemicals that are widespread in commercial laundries, pools, and conventional drinking water and cooling tower disinfection systems. Ozone, a molecule comprising three oxygen atoms, is aggressive against microscopic pathogens in water that are resistant to conventional disinfectants. Our ozone systems are designed to deliver the precise dosage of ozone that is required to disinfect a given amount of water. Any unused ozone is automatically converted back to benign, atmospheric oxygen. An additional asset of our treatment systems from an environmental perspective is that ozone is produced on-site, thereby eliminating the transport, storage, and handling of hazardous chemicals.
Our technology is cutting edge. It has been tested, proven and is award winning.
