Oil in water emulsions serve an array of functions in a variety of scientific and industrial applications.  However, disposal of these materials can be problematic and costly. Ultra-filtration techniques are capable of separating the oil and surfactant components so that the remaining water fraction may be discharged, vastly reducing the volume of waste.  However, this technique requires equipment operating at high pressures to pump the emulsion through specialized membranes which can be prone to fouling, requiring frequent maintenance or change out.  Ultrafiltration is cost prohibitive to many smaller to mid-size industrial operations.  However, the surfanetix adsorbent technology provides a more simplified process to achieve the same results at a fraction of the time and cost.  Furthermore, our approach offers the possibility to not only separate the surfactant and oil components from the water, but also isolate the surfactant from the oil and any other organic components.
