Abstract
The purification apparatus includes UV-tubes and secures a continuous and uniform disinfection or purification, respectively, of a flowing medium such as water, independent which portion of the space containing the UV-tubes is flowed through by such medium. The purification apparatus comprises a cylindrical pressure vessel with two chambers arranged on top of each other and separated from each other by a partition wall. The lower chamber comprises an inlet opening for the medium which is to be purified. The cylindrical upper chamber communicates with the lower chamber by inlet parts for the medium arranged on the partition wall and arranged groupwise along various concentric circles, each having a different radius. Inside of the vessel there is arranged an outlet tube, the upper portion of which is located in the upper chamber and comprises an inflow aperture at its upper end and the lower portion of which penetrates the partition wall and lower chamber and comprises at its lower end the discharge opening of the vessel. In each inlet part of the partition wall a UV-tube is supported at its lower end by the agency of guide vanes which produce a circulation of the incoming medium around the respective UV-tube. The UV-tubes extend through the upper chamber and penetrate an upper center plate and are supported at their upper end in a wall of the vessel remote from the inflow side.

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.
