20140091040 | BICARBONATE CONVERSION ASSISTED RO TREATMENT SYSTEM FOR NATURAL GAS FLOWBACK WATER - 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. | 04-03-2014 |
20130220581 | FORWARD OSMOSIS WITH AN ORGANIC OSMOLYTE FOR COOLING TOWERS - A system is described in which a cooling tower is operated with a solution of a non-volatile organic molecule osmolyte and water. Makeup water for the tower is provided by forward osmosis using the fluid as the draw solution for the extraction of water from feeds which require dewatering or from low value available water. | 08-29-2013 |
20130190539 | SYSTEM AND METHOD FOR SECONDARY USES OF GLYCOL AND WATER AFTER DEICING - A system and method for extracting the glycol from used or spent glycol mixtures, particularly aircraft deicing fluid, and simultaneously using the extracted water to hydrate brines, such as pavement deicing brines, are disclosed. The system provides comprehensive fluid handling and no discharge, as it re-concentrates glycol from spent aircraft deicing fluids. | 07-25-2013 |
20130186827 | FORWARD OSMOSIS MEMBRANE BASED ON AN IPC SPACER FABRIC - A forward osmosis (FO) membrane structure comprising a support based on an integrated permeate channel (IPC) fabric and a forward osmosis membrane embedded in the support is disclosed. | 07-25-2013 |
20130186824 | Spiral Cross Flow Membrane Filtration Device And Process - Disclosed is a membrane filtration device and process affording high velocity cross flow membrane purging via cyclonic spiraling flow; hydraulically induced about stacked plate type membrane configurations. No piping, conduits or other flow impediments are enclosed to generate streamline or shadow depositions, and periodic reversals of cyclonic flow for enhanced membrane scouring and flushing may be employed. | 07-25-2013 |
20130186822 | LOW ENERGY FORWARD OSMOSIS MEMBRANE WATER PROCESSING SYSTEM - Described herein are systems and processes employing a low energy forward osmosis membrane water processing system to simultaneously (1) detoxify reverse osmosis (RO) residual (reject) brines from ground water treatment, and (2) expand available industrial and agricultural ground water supplies. | 07-25-2013 |
20130134093 | OSMOTIC PUMP FOR FORWARD OSMOSIS DEVICES - A self-regulating FO system is disclosed comprising a container containing a source water supply, a forward osmosis membrane element located within the container comprising an area of osmotic membranes, an osmotic agent inlet and a drink outlet, an osmotic pump element also located within the container comprising an area of osmotic membranes, an osmotic agent inlet and a drink outlet, and an osmotic agent tank located above the container. The osmotic agent tank comprises a feed tube connected to an outlet located on the bottom of the osmotic agent tank. The feed tube communicates with the osmotic agent inlet of the forward osmosis membrane unit and the osmotic agent inlet of the osmotic pump element. A return tube communicates with the drink outlet of the osmotic pump element and a port near the top of the osmotic agent tank. | 05-30-2013 |
20130026091 | METHOD TO IMPROVE FORWARD OSMOSIS MEMBRANE PERFORMANCE - Described herein are thin film composite (TFC) membranes, for use in forward osmosis (FO) and pressure reduced osmosis (PRO) processes. The membrane is comprised of two layers: a composite layer combining a backing layer and a porous, polymer-based support into a single layer, and a rejection layer disposed on top of the composite layer. The membrane of the invention exhibits high water flux values for FO processes, is durable, may be readily manufactured using typical membrane manufacturing processes, such as spiral winding and plate and frame processes, and has sufficient mechanical stability to handle the final membrane product. | 01-31-2013 |
20120231535 | Organic Forward Osmosis System - An organic forward osmosis system includes an acid treatment stage comprising an acid treatment operation configured to produce an acid treated, digester centrate stream in a forward osmosis reject loop and a fertilizer stream. A forward osmosis stage is coupled to the acid treatment stage and includes a forward osmosis operation configured to remove water from the acid treated, digester centrate stream by: diverting the acid treated, digester centrate stream to one side of at least one forward osmosis membrane; and contacting an opposite side of the at least one forward osmosis membrane with a salt brine stream in a forward osmosis draw loop and osmotically pulling water across the at least one forward osmosis membrane from the acid treated, digester centrate stream to the salt brine stream using only a concentration gradient; thereby producing a concentrated, acid treated, digester centrate stream and a diluted salt brine stream. | 09-13-2012 |
20110168381 | Osmotic Water Transfer System and Related Processes - A forward osmosis water transfer system is disclosed which recycles water from an incoming wastewater stream into an outgoing dilute process brine stream. The system includes a saturated brine stream, a first portion of which is diverted to form a saturated process brine stream and a second portion of which is diverted to at least one forward osmosis membrane. The at least one forward osmosis membrane moves water from the incoming wastewater stream into the incoming diverted saturated brine stream thereby creating an outgoing concentrated wastewater stream and the outgoing dilute process brine stream. | 07-14-2011 |
20110081469 | OSMOTIC PUMP FOR FORWARD OSMOSIS DEVICES - A self-regulating FO system is disclosed comprising a container containing a source water supply, a forward osmosis membrane element located within the container comprising an area of osmotic membranes, an osmotic agent inlet and a drink outlet, an osmotic pump element also located within the container comprising an area of osmotic membranes, an osmotic agent inlet and a drink outlet, and an osmotic agent tank located above the container. The osmotic agent tank comprises a feed tube connected to an outlet located on the bottom of the osmotic agent tank. The feed tube communicates with the osmotic agent inlet of the forward osmosis membrane unit and the osmotic agent inlet of the osmotic pump element. A return tube communicates with the drink outlet of the osmotic pump element and a port near the top of the osmotic agent tank. | 04-07-2011 |
