  • Patent number: 9227856
    Abstract: Described herein is a submerged plate membrane device intended for use in forward osmosis processes, particularly for concentrating various process streams such as those in ponds. Particular examples of feed streams that may be concentrated are for example the following feed solutions: brines, seawater, drilling mud, waste water, bio-digestate, and the like. Thus, the process and device described herein are useful for de-watering, and thus concentrating, the content of solar evaporation ponds and drilling mud ponds.

  • Publication number: 20140183134
    Abstract: Described herein is a structure for a permeate spacer for use in spiral wound osmosis membrane elements, having at least two sets of parallel ribs, wherein the ribs in the first set are oriented at about a 90 degree angle to the ribs in the second set. The permeate spacer is used by sandwiching it inside a membrane envelope or leaf, and is particularly useful for non-pressure-driven processes, such as forward osmosis (FO) and pressure-reduced osmosis (PRO).

  • Publication number: 20140091040
    Abstract: Bicarbonate conversion assisted reverse-osmosis (RO) treatment systems for treatment of contaminated water, particularly natural gas flowback water. The systems and processes provide for simultaneous conversion of the primary salt in gas production flowback waters from sodium bicarbonate to sodium sulfate, and flotation removal of organic contaminants, for the enhanced water recovery by RO of these waters. In the systems and processes, RO processes are enhanced by lowering the osmotic potential of the water being processed, by converting the bicarbonate ions to sulfate ions.
