Abstract
Water to be treated is passed through a membrane (net), magnetic floc positioned in a portion below a level of the water to be treated is deposited to a surface of the membrane, and the surface of the membrane with the magnetic floc deposited is moved to an atmospheric portion above the level of the water to be treated. In the atmospheric portion, excess water from the magnetic floc flows downward due to gravity to concentrate the magnetic floc. A permanent magnet is located near a position to which the membrane surface with the magnetic floc deposited thereon moves. There are further provided between the magnet and the membrane surface a moving body (shell) formed by a non-magnetic material, a spatula for scraping the magnetic floc from the moving body, and a sludge vessel in which a released magnetic floc is recovered.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
