Abstract
The present invention relates to a filtration device being adapted for continuous vibration and pressure driven filtration. Said filtration device comprises a filter module which comprises at least one tubular semipermeable membrane element, said module further comprises a drain area for permeate, an outlet for permeate, an inlet for feed fluid and an outlet for retentate; said module further comprises one or more flexible volume chambers being filled with gas and in close contact with but separated from the internal module of the filter module through a flexible wall; said filtration device comprises a vibration motor being adapted to provide a vibrating motion to the device.
Claims20
A filtration device, comprising:
- a filter module adapted for filtration of media, the filter module comprising one or more tubular membrane elements, the filter module comprising two gas-filled flexible volume chambers positioned at ends of the filter module, each of the two gas-filled flexible volume chambers providing a cushioning effect on the media in response to external vibration applied to the filter module, the filter module comprising at least one inlet for media to be filtered and at least one retentate outlet for retentate, the at least one inlet and the at least one retentate outlet being positioned at the ends of the filter module, the filter module comprising at least one semipermeable tubular membrane forming a path between the inlet and the retentate outlet, the at least one semipermeable tubular membrane being associated with one of the tubular membrane elements and forming a semipermeable wall separating the retentate from a drain area, the drain area comprising a permeate outlet.
A filtration device, comprising:
- a filter module adapted for pressure and vibration-driven filtration of media, the filter module comprises one or more tubular membrane elements, two or more gas-filled flexible volume chambers each positioned at one end of the filter module, at least one inlet for media to be filtered, and at least one retentate outlet for retentate, the inlet and retentate outlet being positioned at distal ends of the filter module and proximal to the flexible volume chambers, the filter module further including at least one semipermeable tubular membrane associated with one of tubular membrane elements that forms a path between the inlet and retentate outlet, the one semipermeable tubular membrane forming a semipermeable wall separating the retentate from a drain area, the drain area comprising a permeate outlet;
- a vibration motor having a receptacle for mounting the filter module, the vibration motor being adapted to provide a vibrating motion to the filter module, the flexible volume chambers having at least one flexible chamber wall in contact with the retentate flow and being adapted to expand and/or compress their volumes to allow the retentate to undergo a back-and-forth movement relative to a surface the semipermeable membrane in response to the vibrating motion.
A filtration device, comprising:
- a filter module being adapted for continuous pressure and vibration driven filtration of media, the filter module comprising a retentate channel, two or more flexible volume chambers each positioned at an end of the retentate channel, at least one inlet for media to be filtered, and at least one retentate outlet for retentate, the at least one inlet and the at least one retentate outlet being positioned at distal ends of the filter module and proximal to the flexible volume chambers, the filter module further including at least one semipermeable tubular membrane located between the at least one inlet and the at least one retentate outlet and forming a semipermeable wall separating the retentate from a drain area, the drain area comprising a permeate outlet;
- and
- a vibration motor having a receptacle for mounting the filter module, the vibration motor being adapted to provide a vibrating motion to the filter module, the flexible volume chambers having at least one flexible chamber wall in contact with the retentate flow and being adapted to expand and/or compress their volumes to allow the retentate to undergo a back-and-forth movement relative to a surface the semipermeable membrane in response to the vibrating motion.
