摘要： A submersible reverse osmosis desalination apparatus uses low temperature concentrate or brine from the desalination apparatus to provide a high volume cold liquid stream to an Ocean Thermal Energy Conversion (OTEC) heat engine. The OTEC engine also employs a warm liquid stream and uses the cold and warm liquid streams to obtain electrical power from a closed-cycle or open-cycle heat exchange and generator system. Use of the concentrate or brine stream provides a much greater liquid volume and much greater cold thermal energy content than would be obtained by using cold desalinated product water from the desalination apparatus in the OTEC heat engine.

摘要： Portable water conditioning systems include a water conditioner having a plurality of conditioning stages including, in a direction of flow of the water through the water conditioner, a reverse osmosis stage having a reverse osmosis membrane, and a deionizing stage. A first sensor is configured to detect a first condition of the water before the reverse osmosis stage and a second sensor configured to detect a second condition of the water after the reverse osmosis stage. The conditions each include (i) a level of total dissolved solids of the water and (ii) temperature of the water. A controller is in communication with the sensors and configured to determine of a percent of dissolved solids that are rejected by the reverse osmosis membrane based on the conditions when backpressure on the reverse osmosis stage is at a known state.
