  • Microorganism concentrator
    Patent number: 10260997
    Abstract: A microorganism concentrator includes a water storage part that stores water sample therein and a filter that partitions the water storage part into a supply side and a drain side for the water sample. The microorganism concentrator concentrates microorganisms that are too large to pass through the filter on the supply side by moving the water sample on the supply side to the drain side of the water storage part. In the microorganism concentrator, the filter is arranged in such a way that no vertically downward force is applied to a surface of the filter on the supply side.
    Type: Grant
    Filed: July 2, 2014
    Date of Patent: April 16, 2019
    Assignee: SATAKE CORPORATION

  • Method for treating ship ballast water
    Patent number: 8123958
    Abstract: A method for treating ship ballast water in which aquatic organisms in the ship ballast water are exterminated by adding hydrogen peroxide or a compound producing hydrogen peroxide in an amount such that a hydrogen peroxide concentration comes to be 10 to 500 mg/L to the ship ballast water, and then providing physical means for causing shear strength and/or cavitation to the ship ballast water.
