Patent number: 7563362Abstract: The automatic regenerable cold/hot water softener includes a water softening tank having ion exchange resin and a regenerating tank filled with regenerating substance of the ion exchange resin. The water softener controls the mode for receiving raw water and discharging soft water using one switching valve, a direct water mode for discharging raw water itself, a regeneration mode for regenerating ion exchange resin, and a intermittence mode for intermitting the inflow and outflow of the raw water and the soft water. The precise regeneration time is judged according to used amount of the soft water by a temperature sensor and a flow meter for sensing temperature and flux of supply raw water. The regeneration is automatically prosecuted by a control part having a microprocessor. The cold/hot water softener serves a user's convenience in that sudden change of temperature is prevented.Type: GrantFiled: November 8, 2004Date of Patent: July 21, 2009Assignee: Seung Gwang Co., Ltd.Inventor: Seung-Hoon Jeong

Publication number: 20090057228Abstract: A stratified bed of activated carbon having regions of functionalized and non-functionalized activated carbon can be utilized to remove contaminants from fluids such as groundwater. The functionalized region has activated carbon particles comprising a cationic or anionic compound that can remove organic or inorganic anionic or cationic compounds from the fluid to be treated. The non-functionalized region comprises powdered or granular activated carbon or adsorbent media downstream of the functionalized region and captures any leaching species or compounds from the functionalized region.Type: ApplicationFiled: August 29, 2007Publication date: March 5, 2009Applicant: SIEMENS WATER TECHNOLOGIES CORP.Inventors: James R.

Publication number: 20080289371Abstract: A water softener which uses ion exchange resins to soften water and a washing machine having the same are disclosed. The water softener and the washing machine having the same include an ion exchange unit including ion exchange resins therein, the ion exchange unit including a first ion exchange unit and a second ion exchange unit which alternately perform softening of water and regeneration of the ion exchange resins. Since any one of the first ion exchange unit and the second ion exchange unit performs softening of water and the other one thereof performs regeneration of the ion exchange resins, it is possible to continuously supply soft water.Type: ApplicationFiled: April 21, 2008Publication date: November 27, 2008Applicant: Samsung Electronics Co., Ltd.Inventors: Jung Yoon Hahm, Vladimir Urazaev, Jin Ha Jeong, Hideo Nojima

Publication number: 20080283454Abstract: Remote delivery of water softener pellets into a water softener by means of vacuum. By using a vacuum the delivery system allows salt to be delivered to great distances to point of use (existing brine tank). This invention will allow people to drive into their garage close to the inventive salt loading hopper and either dump a bag of salt pellets or scoop out of it into the loading hopper, which is located a convenient minimized height off the floor. The current state prior to this invention was to carry the heavy bag of salt to the location of the water softener brine tank, which in most cases is located down the stairs in a basement.Type: ApplicationFiled: March 13, 2007Publication date: November 20, 2008Inventor: Michael J. MUNIAK

Publication number: 20080264851Abstract: A water softener is composed of a cabinet of a resin bed, a brine tank, and a brine valve. The improved water softener has an outer housing having sides, a bottom, and an open top. A wall is disposed within the housing forming a brine chamber and a resin bed chamber for housing ion-exchange resin beads. Cross-contamination of the resin beads by the brine is prevented.Type: ApplicationFiled: April 25, 2007Publication date: October 30, 2008Applicant: Wm. R. Hague, Inc.Inventor: Keith A. Emerson
