Filed: 1997-02-26
Granted: 2002-07-11
Abstract: A process to treat waste water or sludge can detoxify the hazard chemical materials and stabilize heavy metal compounds. The treatment method applies cyclodextrins and natural microorganisms to handle waste water treatment. Cyclodextrins encapsulate hazard chemical materials and provide the marking effect in the waste water, and the microorganisms dissolve and digest the cyclodextrins with capsulated chemical materials. Through this bio-chemical reaction, the microorganisms also oxidize the cyclodextrins with connected metal materials. The initial hazard chemical materials in the waste water are converted into organic matters by applying the cyclodextrins and microorganisms, and the oxidized metals, after proper separation, can recover for other usages.

Title: Washing maching having a water guide for forming vertical and horizontal currents of wash water
Inventor: KIM YOUNG-CHUL
IPC: D06F37/12
Filed: 1998-07-22
Granted: 2000-09-11
Abstract: Disclosed is a washing machine having a water guide for forming a vertical and a horizontal flow of wash water. The washing machine comprises a Washing and dehydrating tub for receiving the wash water; a pulsator for forming a rotational water flow within the washing and dehydrating tub; and a water guide provided to an inner peripheral surface of the washing and dehydrating tub for defining a vertical passageway along the washing and dehydrating tub. While the wash water is rotated by the rotational movement of the pulsator, some of the water is guided is guided along the passageway to the upper side of the washing and dehydrating tub where the wash water falls to the inner side of the washing and dehydrating tub. The water guide has a main passageway and a pair of auxiliary passageways. An upper discharge port is formed at the upper portion of the main passageway, and the wash water is discharged through the upper discharge port. The auxiliary passageways have middle discharge ports for forming the side water stream. Thus, the wash water flows in to the inflow section of the water guide and then flows through the passageway upward. Some of the upwardly flowing wash water is discharged through the upper discharge port, while the other horizontally flows out from the middle discharge ports. Accordingly, during a washing /rinsing process, there are two streams of wash water, i.e., the vertically falling wash water which falls from the upper discharge port, and the horizontally flowing wash water which flows out from the middle discharge ports. The side water stream pushes the clothes to be washed to the center of the washing and dehydrating tub, while beating the clothes. Accordingly, the clothes to be washed are beaten by the vertical water stream and the horizontal water stream so that the washing /rinsing performance of the washing mashing is mush enhanced.
