Abstract:
The present invention relates to a unit and a method for exposing fluid, typically being a liquid, to treatment. The invention relates in particular to a fluid treatment unit with a flow passage through which fluid may flow while being exposed to radiation emitted from an ultrasound source. The fluid treatment unit further comprises one or more total pressure increasing means for increasing the total pressure of fluid at least locally in the fluid treatment unit and a casing which encapsulates the flow passage and the one or more total pressure increasing means.
Abstract:
The present invention relates to a heat exchanger (1) arranged for heat exchange between a first (F1) and a second fluid (F2). The heat exchanger comprises: first (5a) and a second (5b) tube, the first and second tube being adapted for fluid conduction of the first fluid and the second fluid, respectively, through the heat exchanger, and a first rotatable impeller (3, 3a) being arranged to so that the first fluid flowing into the first tube comprises a spiraling flow pattern (S1) having an axial velocity component (Va_1) and a tangential velocity component (Vt_1). The heat transfer can be dynamically changed during operation by changing the swirl pattern by changing the rotational velocity of the rotating impeller and/or a flow rate of the first and/or the second fluid through the heat exchanger. This is achieved by effectively de-coupling the local fluid velocity in the heat exchanger with the fluid flow rate trough the heat exchanger by having a relatively high swirl number S in the heat exchanger.
Abstract:
The invention relates to a forward osmosis (FO) device (10) with a semipermeable membrane (5, 5a) capable of performing forward osmosis between a first (F1) and a second fluid (F2). In a first fluid confinement (4a), a first swirl generator (7a) is positioned and in a second fluid confinement (4b) positioned on the other second side of the membrane, a second swirl generator (7b) is positioned. The swirl generators are arranged to create a circular flow pattern (S2, S3) for the first and the second fluid, respectively,wherein the first (7a) and second (7b) swirl generator, upon engagement, are arranged to create a circular flow pattern for the first and the second fluid, respectively, by rotating motion (RA1, RA2). The invention is advantageous by obtaining FO device that is capable of reducing the concentration polarisation (CP) near the membrane by creating a cross flow velocity over the membrane and facilitate control of the cross flow velocity independent of the through flow of the membrane. The external concentration polarization can thereby be controlled and further reduced.

Abstract:
The invention relates to a method of controlling the transferral of heat, substance, radiation or the like to or from at least a first fluid in a device. The device comprises a stage with a transferring element (2) and a rotatable impeller (3), the impeller being arranged so that the first fluid flowing out of the impeller flows along a surface of the transferring element (2). The flow of the first fluid along the surface of the transferring element comprises a spiralling flow pattern having a radial velocity component (Vr) and a tangential velocity component (Vt), the device further comprises one or more throttling means for throttling the flow of the first fluid through the device. The rotational speed of the impeller and the throttling is mutually controlled so that:l) the amount of transferral is a function of the radial velocity component (Vr) and a function of the tangential velocity component (Vt), and2) the radial velocity component (Vr) and the tangential velocity component (Vt) are substantially independent.

The unit comprises a flow passage, at least one fluid interaction component or is adapted to receive at least one fluid interaction component, at least one of the at least one fluid interaction components comprising dosing means for dosing a substance into the fluid flowing through the processing unit. The unit further comprises one or more heat transferring elements for exchanging heat with the fluid flowing through the device, and one or more total pressure increasing means for increasing the total pressure of fluid to be processed at least locally in the fluid processing unit, The unit further comprises a casing encapsulating the one or more heat transferring elements, the one or more total pressure increasing means and the at least one fluid interaction component. The casing forms at least part of the wall of the fluid processing unit which confines fluid in the processing unit so that fluid may flow into / out of the processing unit through one or more inlets and outlets provided in the casing.

Abstract:
Der Reaktor weist ein rohrförmiges Gehäuse (18, 19, 20) auf, in welchem ein Filterplattenstapel (1) rotierbar angeordnet ist. Die Querschnittsfläche des Reaktorbehälters (18, 19, 20) ist im Bereich des Filterplattenstapels um höchstens 40 % größer als die Querschnittsfläche des Filterplattenstapels (1). Die Längserstreckung (I) des Reaktorgehäuses (18, 19, 20) beträgt ein Vielfaches der Längserstreckung (h) des Filterplattenstapels (1), so dass innerhalb des Reaktors neben dem Filterplattenstapel (1) weitere Behandlungseinrichtungen (24, 25) angeordnet werden können, wobei der rotierende Filterplattenstapel für eine intensive Durchströmung des gesamten Reaktors sorgt.
