    摘要: An apparatus and methods for softening water is disclosed. In particular, an apparatus and method for softening water without the addition of ions the wastewater stream is disclosed. The apparatus generally includes at least one nanofiltration filter element configured and arranged to receive an input flow of hard water, discharge an output flow of permeate water comprising a portion of the input flow, and discharge an output flow of non-permeate water comprising a portion of the input flow. The nanofiltration filter element typically has an average pore size that permits the passage of water and monovalent ions but substantially prevents the passage of divalent ions.

    摘要: A system and method of degumming a plant derived oil comprising mixing a feed stream under ultrahigh shear conditions to provide a mixed stream, passing the mixed stream through a retention tank, and separating the mixed stream into an aqueous stream and an oil stream is disclosed. The feed stream comprises water, optional added acid(s), and triglyceride oil, such as a plant derived oil, having a relatively high phosphorous content and may also include metal impurities such as calcium, magnesium and/or iron ions. The process can provide a triglyceride oil stream with a phosphorous content of no more than about 10 to 20 ppm and no more than about 0.5 wt.% free fatty acids. In many instances, the triglyceride oil stream has phosphorous content which is no more than about 3% of the phosphorous content of the feed stream. The process also provides a wet gum stream, which may have an AI of 75 or higher.
