20100258442 | ELECTRONIC OSMOTIC DEHYDRATOR OF ELECTROPHORESIS STYLE WITH A PHASE CONTROL USING THREE-PHASE CURRENT - The present invention relates to An electronic osmotic dehydrator of electrophoresis style with a phase control using three-phase current, and more specifically, to An electronic osmotic dehydrator of electrophoresis style with a phase control using three-phase current, which can minimize an unnecessary loss of power consumed in the rotating drum itself by emboding the applying structure of the DC power supplied to the dehydrating domain of the electro-osmotic dehydrator so that a strength of the electric field generated between the rotating drum and the caterpillar may be variably controlled depending upon a sludge volume, and improving a structure of the rotating drum to which the DC power is applied, when forming an electronic osmotic dehydrator comprising a rotating drum in the cylindrical form, a caterpillar running on an endless track at a certain space from the rotating drum and two filter cloth belts for transferring and dehydrating the sludge as wound between the drum and the caterpillar, which is a continued invention of ‘an electro-osmotic dehydrator (K.R. Patent Application No. 10-2004-007759)’, ‘an electro-dehydrator of a phase control type (K.R. Patent Application No. 10-2005-009928)’, and ‘an electro-osmotic dehydrator (K.R. Patent Application No. 10-2007-046494)’ which were already filed by the applicant of the present invention. | 10-14-2010 |
20120145550 | APPARATUS FOR REMOVING IONS IN COOLING WATER FOR FUEL CELL VEHICLE - Disclosed is an apparatus for efficiently removing ions contained cooling water used in cooling a fuel cell stack. More specifically, the present invention removes ions by trapping ions contained in cooling water using a permeable membranes capable of making ions selectively pass therethrough and electrodes which are configured to attract ions. The present invention can reduce electric power consumption in pump and can modify the overall performance of the system to cope with various environmental conditions. | 06-14-2012 |
20130248371 | Electrodeionization Device And Method Comprising Control Of The Electric Current By Measurement Of Ion-Exchange Material Expansion - Device for the removal of ions from a polar liquid, e.g. water, comprising at least one compartment which comprises at least one inlet for an entering polar liquid flow and at least one outlet for an outgoing deionized liquid flow, in which said compartment an electrochemically regenerable ion-exchange material fills a zone through which zone a liquid flow is able to pass, the device being characterized in that it comprises one sensor of at least one dimensional change of the ion-exchange material. The sensor can comprise a photo-sensor or a sensor of mechanical stress. Preferably an apparatus connected to the sensor is able to analyze this dimensional change and to control the electric current. Method of using said device, whereby the electrical current applied to the device is controlled according to the expansion of the resin. | 09-26-2013 |
20160376174 | DEVICE FOR TREATING WATER BY CDI METHOD - A device for treating water by CDI method according to the present invention comprises a filter unit including first and second filter parts having a water-purifying mode of discharging purified water by purifying raw water and a regeneration mode of regenerating an electrode according to the CDI method; and a control unit for controlling the filter unit. Here, if any one of the first and second filter parts is in the water-purifying mode for a first time, the other one is in the regeneration mode for a second time. In addition, if the water-purifying mode stops in the middle of the first time, the control unit stops the regeneration mode and then performs a first control of flushing the filter part in the regeneration mode with the raw water for a third time. | 12-29-2016 |
