Publication number: 20080047897Abstract: A method of recycling waste water is preferably provided in which hardness and gas are removed from the waste water. Additionally, salt and organic carbon are preferably removed from the waste water using high-efficiency reverse osmosis. The pH of the waste water can be controlled to optimize the processes. The recycled semiconductor waste water can then be made available for use as industrial water for performing a semiconductor fabrication process. As a result, a cost for manufacturing a semiconductor device may be reduced. The principles of the present invention also provide a more environmentally friendly manufacturing method, since it produces less semiconductor waste water when being performed than conventional methods.Type: ApplicationFiled: August 16, 2007Publication date: February 28, 2008Applicants: SAMSUNG ELECTRONICS CO., LTD., SAMSUNG ENGINEERING CO., LTD.Inventors: In-Ho Jeong, Jae-Dong Hwang, Sung-Kwang Eun, Byung-Moon Choi, Sun-Pil Kim, Deung-Yoon Heo

Patent number: 6372138Abstract: A wastewater treatment method for removing organic matter and nitrogen from wastewater. In the wastewater treatment method, an excessive amount of organic matter which prevents nitrifying bacteria from growing is removed in a leading aeration tank, and the conditions of the aeration tank are optimized using the nitrifying carrier to which a great amount of nitrifying bacteria can be attached for growth, such that the nitrifying bacteria can multiply therein. As a result, a large amount of wastewater can be treated within a short time, and it is possible to stably cope with a change in load of the organic matter of the wastewater. Thus, the wastewater treatment apparatus can be smaller, and an improvement in performance thereof can be expected. Also, the wastewater can be treated stably during the winter season when the activity of the nitrifying bacteria becomes low, so that the wastewater treatment method according to the present invention can be applied to most wastewater treatment plants, e.g.Type: GrantFiled: September 27, 2000Date of Patent: April 16, 2002Assignee: Samsung Engineering Co., Ltd.Inventors: Jae-hyun Cho, Yong-hwan Kim, Yong-woo Lee, Won-kwon Lee

Patent number: 6139743Abstract: A wastewater treatment apparatus for removing nitrogen and phosphorus contained in wastewater, and a method therefor. The wastewater treatment apparatus includes an anaerobic/anoxic reaction tank having multiple compartments partitioned by a plurality of partitions, each compartment receiving wastewater and a carbon source; an aeration tank for removing phosphorus by luxury uptake of phosphorus from the treated wastewater flowed from the last compartment of the anaerobic/anoxic reaction tank, using oxygen as an electron acceptor; and a settling tank for settling a sludge from the treated wastewater passed from the aeration tank, and returning the settled sludge into the anaerobic/anoxic reaction tank. The wastewater treatment apparatus can increase removal efficiencies of nitrogen and phosphorus contained in the wastewater, even at a low temperature. Also, the retention time in the reaction tank is reduced, so the size of the reaction tank is reduced, thereby lowering construction costs.Type: GrantFiled: June 11, 1998Date of Patent: October 31, 2000Assignee: Samsung Engineering Co., Ltd.Inventors: Jong-bok Park, Keum-hee Jung, Jeong-hee Sohn
