| 20080197071 | Nano Composite Hollow Fiber Membrane and Method of Manufacturing the Same - Disclosed are a nanofiltration composite hollow fiber membrane and a method of manufacturing the same. The nanofiltration composite hollow fiber membrane includes a reinforcement ( | 08-21-2008 |
| 20080199619 | Method Of Manufacturing For Aromatic Polyamide Composite Membrane - The present invention provides a method of manufacturing an aromatic polyamide composite membrane comprising: coating an aqueous solution containing polyfunctional aromatic amine to a porous polymer substrate; and reacting the coated substrate with an organic solution containing polyfunctional aromatic acyl halide to lead to interfacial condensation polymerization between the polyfunctional aromatic amine and the polyfunctional aromatic acyl halide so that the reaction product resulting from the interfacial condensation polymerization is coated on the surface of the substrate, characterized in that either of the aqueous solution containing polyfunctional aromatic amine or the organic solution containing polyfunctional aromatic acyl halide has dendritic polymer as one of polyfunctional compounds added thereto. The resulting aromatic polyamide composite membrane which includes dendrimer as polyfunctional compound, exhibits high salt rejection rate and water flux. | 08-21-2008 |
| 20080230466 | Submerged Hollow Fiber Membrane Module - Disclosed is a submerged hollow fiber membrane module which is easy to expand, has a small installation area, and exhibits excellent contamination prevention and durability. The submerged hollow fiber membrane module comprises: (I) a module body divided into two portions which has a permeated water collection space ( | 09-25-2008 |
| 20090285008 | MEMORY DEVICES WITH SELECTIVE PRE-WRITE VERIFICATION AND METHODS OF OPERATION THEREOF - A number of read cycles applied to a selected memory location of a memory device, such as a variable-resistance memory device, is monitored. Write data to be written to the selected memory location is received. Selective pre-write verifying and writing of the received write data to the selected memory location occurs based on the monitored number of read cycles. Selectively pre-write verifying and writing of the received write data may include, for example, writing received write data to the selected memory cell region without pre-write verification responsive to the monitored number of read cycles being greater than a predetermined number of read cycles | 11-19-2009 |
| 20100124102 | Phase-Change and Resistance-Change Random Access Memory Devices and Related Methods of Performing Burst Mode Operations in Such Memory Devices - Phase-change and resistance-change random access memory devices are provided which include a phase-change or resistance-change memory cell array and a sense amplifier that is configured to amplify data read from the phase-change memory cell array. These random access memory devices are configured to read data from a first word line of the phase-change or resistance-change memory cell array and to insert a dummy burst in which no data is read when a first boundary crossing occurs during a burst mode operation. Related methods of operating phase-change and/or resistance-change random access memory devices in burst mode are also provided. | 05-20-2010 |
| 20100192976 | APPARATUS FOR CLEANING A MEMBRANE MODULE AND A METHOD THEREFOR - Disclosed are an apparatus for cleaning a membrane module and a method therefor, which can minimize consumption of chemicals required to clean the membrane module while maximizing a recovery cleaning rate of the membrane module without completely stopping a water treatment operation. The cleaning apparatus includes a first flushing bath for flushing a membrane module transferred from a water treatment tank, and a first chemical cleaning bath for cleaning the membrane module, which has been completely flushed and transferred from the first flushing bath, by use of a first chemical solution. | 08-05-2010 |
| 20110024345 | HOLLOW FIBER MEMBRANE MODULE AND PULLER USED THEREFOR - A hollow fiber membrane module ( | 02-03-2011 |
| 20110220572 | FILTERING SYSTEM AND METHOD - Disclosed is a filtering system and method which facilitates to maximize cleaning efficiency, minimize heat energy consumption for cleaning, and shorten cleaning time by a concentrated heating only in a filtering membrane for a maintenance cleaning or recovery cleaning, wherein the filtering system comprises a membrane module including a filtering membrane; an air supplying means for cleaning the filtering membrane; and a heater for heating air supplied from the air supplying means. | 09-15-2011 |
