| 20090188799 | METHOD AND APPARATUS FOR GENERATING A HIGH PURITY ELUANT - An apparatus and method for electrochemically modifying the retention of a species on a chromatography material is disclosed. The apparatus comprises a housing having an effluent flow channel adapted to permit fluid flow therethrough. The effluent flow channel comprises chromatography material. The apparatus further comprises first and second electrodes positioned such that at least a portion of the chromatography material is disposed between the first and second electrodes, and fluid flow through the apparatus is between, and in contact with, the first and second electrodes. | 07-30-2009 |
| 20100116664 | Monitoring and manipulating cellular transmembrane potentials using nanostructures - The use of nanostructures to monitor or modulate changes in cellular membrane potentials is disclosed. Nanoparticles having phospholipid coatings were found to display improved responses relative to nanoparticles having other coatings that do not promote localization or attraction to membranes. | 05-13-2010 |
| 20110203928 | SILICA REMEDIATION IN WATER - Water treatment methods for reducing silica concentration in water containing at least 100 ppm dissolved or suspended silica include contacting the water with particles comprising mesoporous alumina having surface area ranging from about 250 m2/g to about 600 m | 08-25-2011 |
| 20120080314 | SPLIT FLOW EDI APPARATUS FOR TREATING SECOND PASS RO PERMEATE WATER WITH HIGH FLOW RATE - We report an electro-deionization (EDI) device having split flow arrangement for the purification of second pass RO permeate water with high flow rate in which the feed water is fed through the center port and is diverted into each section of dilute chamber with equal flow rate, producing two product streams. The EDI device has concentrate chambers adjacent to dilute chambers in two sections of the stack, allowing independent flow through the separate sections. The split flow design reduces resin bed depth requirement for processing of second pass RO permeate water. This results in higher flow rate through the stack, elimination of the pressure drop limitation, and reduction of power consumption per unit volume of water. | 04-05-2012 |
| 20130008791 | METHOD AND SYSTEM FOR IRRIGATION - An electrically-driven separation apparatus can be utilized to desalinate seawater and/or brackish water to provide irrigation water having a desired sodium adsorption ratio (SAR). | 01-10-2013 |

| 20130256135 | WATER TREATMENT SYSTEM AND METHOD - A treatment system provides treated or softened water to a point of use by removing at least a portion of any undesirable species contained in water from a water source. The treatment system can be operated to reduce the likelihood of formation of any scale that can be generated during normal operation of an electrochemical device. The formation of scale in the treatment system, including its wetted components, may be inhibited by reversing or substituting the flowing liquid having hardness-causing species with another liquid having a low tendency to produce scale, such as a low LSI water. Various arrangements of components in the treatment system can be flushed by directing the valves and the pumps of the system to displace liquid having hardness-causing species with a liquid that has little or no tendency to form scale. | 10-03-2013 |
