Patent number: 10941065Abstract: This combined dehydration device continuously supplies primarily dehydrated sludge to a sludge supply part, the combined dehydration device including: a multiple rotary disk-type solid-liquid separation device and an electroosmosis dehydration device. In the multiple rotary disk-type solid-liquid separation device, a plurality of rotary shafts in which a plurality of rotary disks are fitted and mounted are arranged from the upstream side toward the downstream side and pivotally supported; while the rotary disks are rotated, water to be treated including sludge is supplied from over the rotary disks at the upstream side and is subjected to a primary dehydration treatment; and first dehydrated sludge on the rotary disks is fed and discharged from a sludge discharge part located at the most downstream portion of the rotary disks. In the electroosmosis dehydration device, a sludge supply part is provided at the upstream side of an endless filtration fabric spread between rollers.Type: GrantFiled: August 16, 2017Date of Patent: March 9, 2021Assignee: ABLE CO., LTD.Inventors: Toshiki Yoshimura, Takeshi Okada, Keisuke Uchimura, Shu Ting Zhang

Patent number: 6773597Abstract: The invention offers a method and apparatus for solubilizing excess sludge, having a high solubilizing ability, a low total cost, and capable of reducing the size of facilities. The method for reducing excess sludge comprises adding a solubilizing agent to excess sludge generated by microbial treatment of organic sewage, applying ultrasonic waves, applying a reduced pressure swelling step, then returning the result to the microbial treatment, whereby the volume of the excess sludge can be reduced. The apparatus for reducing excess sludge comprises means for adding a solubilizing agent to excess sludge generated by applying a microbial treatment to organic sewage, ultrasonic wave applying means for applying ultrasonic waves, and reduced pressure swelling means provided downstream of the ultrasonic wave applying means for applying a reduced pressure swelling process to the excess sludge.Type: GrantFiled: October 8, 2002Date of Patent: August 10, 2004Assignees: Able Co., Ltd.Inventors: Shu Ting Zhang, Toshiki Yoshimura, Kunihiko Miseki

Patent number: 5897771Abstract: An apparatus for aerobic biological treatment of waste water is described, in which a great number of carrier members having a large surface area to which microorganisms adhere are movably set in a cylindrical reactor within a given range of height, and the carrier is horizontally moved substantially continuously so that a part of the carrier is cleaned with cleaning air. The partial cleaning system eliminates the disadvantages associated with intermittent cleaning of the whole carrier.Type: GrantFiled: September 29, 1997Date of Patent: April 27, 1999Assignee: Able Co., Ltd.Inventor: Toshiki Yoshimura
