1.Description of Water Treatment Equipment

Our membrane filtration system uses advanced hollow fiber or ceramic technologies which operate in the outside-in or inside-out direction of flow. Given the small membrane pore sizes used with these technologies, fouling due to deposition of organic and inorganic compounds on the membrane may occur if the ultrafiltration system is not properly designed and operated. Therefore, we use automated backwashing, air scour and chemical flushing processes to restrict the rate of membrane fouling within acceptable limits. Chemical cleaning is employed once the maximum transmembrane pressure has been reached. Typical cleaning agents utilized include acids, caustic, surfactants, enzymes and certain oxidants, depending upon membrane material and fouling type.
