摘要:
The present invention relates to a filtering apparatus for filtering raw water containing various impurities and mixtures into purified water, and more particularly to a multistage filtering apparatus in which rotors for generating vortex are installed in each of multiple layers of filtration membrane stacked within a closed barrel (13) and the rotors (17) are formed in multistage by having different diameter of each rotor so that the power for generating vortex can be remarkably minimized by generating the vertical vortex from top and bottom of the rotary rotor and the horizontal vortex from the outer side of circumference plate of the rotary rotor to be crossed over between membranes to prevent from blocking the pores or remove the deposited pollutants, and the closed-type barrel having multistage of membranes (14), rotary shaft, and rotary rotors for vortex generation within are constructed as a single module of filter pack, and the filter pack is connected and extended in accordance with required purified capacity so that large scale installation of filtering apparatus is possible.
摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Trennen einer Suspension in ein eingedicktes Retentat und ein Permeat. Dabei wird die Suspensions in einen Suspensionsraum eingeleitet, in welchem mindestens ein permeables Trennelement mit einer Trennfläche vorgesehen ist. Zumindest ein Rührglied in dem Suspensionsraum wird in einem geringen Abstand über die Trennfläche relativ zu dieser bewegt. Dabei wird in einem Spalt zwischen dem Rührglied und der Trennfläche eine Strömung quer zur Trennfläche erzeugt. Durch Anlegen eines Differenzdrucks zwischen dem Suspensionsraum und einem Permeatraum durchdringt das Permeat das Trennelement. Das Permeat wird über eine Permeatleitung abgeleitet. Zur Vermeidung des Anfiltrierens einer Grundschicht wird in bestimmten Zeitabständen der Differenzdruck für eine definierte Zeitspanne aufgehoben, während der das Rührglied weiter über die Trennfläche bewegt wird. Das Aufheben des Differenzdrucks wird mittels Öffnen oder Schließen von Ventilen erzeugt, welche an der Permeatleitung, dem Zulauf oder dem Ablauf vorgesehen sind.

A plasma separating apparatus comprising a housing (2) provided with a blood inlet port (5), a plasma outlet port (6), and a blood cell outlet port (7); a rotor (3) rotatably held in the housing; a blood separating space (18) formed between the outside surface of the rotor (3) and the inside surface of the housing (2) and communicating with the blood inlet port (5) at its upper part and with the blood cell outlet port (7) at its lower part; a plasma passage (19) enclosing at least a part of the circumference of the blood separating space (18) and communicating with the plasma outlet port (6); and a plasma separating membrane (8) disposed so as to partition the blood separating space (18) and the plasma passage (19).
摘要:
The invention relates to a reactor unit for treatment of a liquid. The reactor unit comprises a number of parallel filtering plates (40) of a liquid permeable material, where each filtering plate (40) has an outlet opening (44) for outletting liquid which has permeated into the plate. The reactor unit moreover comprises a number of aeration plates (50) of a gas permeable material, where each aeration plate (50) has an inlet opening (51) for inletting air, and where the aeration plate(s) (50) are placed in parallel to the filtering plate(s). The aeration and filtering plates (40, 50) are arranged to be stationary within the reactor unit. The reactor unit moreover comprises at least one disc member (12) placed adjacent to a filtering plate (40) or an aeration plate (50), but leaving a gap between said filtering plate (40) or aeration plate (50) and the disc member, as well as means for rotating (7; 16) the at least one disc member around a central axis through the at least one disc member (12).

The invention relates to a reactor unit for treatment of a liquid. The reactor unit comprises at least one plate (30) of a permeable material, said at least one plate being arranged to be stationary within the reactor unit, at least one disc (12), the disc(s) being arranged to be placed adjacent to one of the at least one plate, but leaving a gap between said one plate and the disc member, and in parallel to said one plate; and means (16) for rotating the at least one disc member around a central axis through the at least one disc member. Preferably, the at least one plate comprises a first number of filtering plates of a first material, said first material being permeable to liquid, each filtering plate having outlet means for outletting liquid which has permeated into the plate, and/or a second number of aeration plates of a second material, said second material being permeable to air, each aeration plate having inlet means for inletting air, said aeration plate(s) being placed in parallel to the filtering plate(s).
