  • WHAT WE DO

    EP Purification manufactures novel and environmentally-sound systems for the purification of water and air. Based on microcavity plasma technology developed at the University of Illinois, EP Purification ozone products are efficient, robust, and more than a factor of ten smaller in weight and volume than conventional technology. EP Purification systems are the result of more than a decade of research and engineering, and are protected by more than 50 U.S. and international patents.

     

    Because ozone is the strongest disinfectant and oxidizer available commercially, EP Purification ozone systems are being used worldwide for the disinfection of drinking and pool water, the treatment of chemical wastewater and cooling tower water, disinfection of water for agriculture (hydroponics, spraying of vegetables and fruit), extension of food lifetimes, and commercial and institutional laundries.

     

    Ozone is increasingly replacing chlorine-based products for disinfection applications, not only because of the extraordinary efficacy of ozone in destroying micropathogens, but also due to the adverse impact of chlorine on the environment and water resources, in particular.

     

    Founded in 2010, EP Purification is located in Champaign, Illinois (USA) and provides a wide range of ozone system products as well as technical and consulting services. An international office of EP Purification in South Korea provides sales and technical services to customers throughout Asia.

  • ABOUT THE LOGO AND EP PURIFICATION SPONSORS
    The Chambered Nautilus is a tropical cephalopod having a spiral shell with a pearl-like interior. It has long been associated with the deep, clean waters near coral reefs in the Indo-Pacific oceans.

THE TECHNOLOGY
  • EFFICIENT AND LIGHTWEIGHT MICROPLASMA DISINFECTANT AND WATER TREATMENT SYSTEMS

    EP Purification products are based on microplasma technology, a unique, and proprietary technology that has been engineered into a series of efficient and rugged ozone systems that are revolutionizing and expanding the applications of ozone treatment in the agricultural, potable water, chemical, health care, and water treatment industries. Because ozone surpasses chlorine and other traditional disinfectants in its ability to neutralize pathogens (such as legionella and MRSA), it is of considerable value in replacing highly toxic chemicals such as the biocides widely used in cooling towers. Ozone is produced directly from air or pure oxygen and is environmentally-friendly because, after disinfecting water, it quickly reverts back to atmospheric oxygen.

  • MICROPLASMA PROPERTIES, MICROCHANNEL PLASMAS

    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, EP Purification 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 (right) 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 (right) 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 EP Purification 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.

  • MODULAR DESIGN

    EP Purification has 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.

     

    For larger production rates, EP Purification modules are combined to yield any production rate desired. EP Purification systems are a ground-breaking development in ozone purification because a single, efficient technology is capable of meeting any industrial requirement, from grams/hour to tonnes/day. “Massively parallel” chemical processing is the future of plasma generation because ozone is produced simultaneously in thousands (or millions) of microchannels, each of which is designed such that the processing conditions are optimized. Because the microplasma chips are robust and light, the entire system is compact and reliable. An additional asset to the customers of EP Purification systems is that web-based monitoring of the operation of all ozone systems is offered as an optional service.

  • ENVIRONMENTALLY-SOUND WATER DISINFECTION SYSTEMS

    EP Purification 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. EP Purification 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 EP Purification systems from an environmental perspective is that ozone is produced on-site, thereby eliminating the transport, storage, and handling of hazardous chemicals.
