1-14. (canceled)
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 or more gas-filled flexible volume chambers positioned at ends of 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 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.
The filtration device according to claim 1, wherein each of the gas-filled flexible volume chambers comprises (i) a flexible gasket adapted to separate a gas volume of the flexible volume chambers from a remainder of the filter module, and (ii) rigid walls coupled to the flexible gasket.
The filtration device according to claim 1, wherein the semipermeable tubular membrane is formed on an inside or an outside of the tubular membrane element.
The filtration device according to claim 1, wherein the semipermeable tubular membrane is formed on an inside of one or more tubular cavities in the tubular membrane elements.
The filtration device according to claim 1, wherein the flexible volume chambers can be connected to a gas pressure source for increasing or decreasing volume of the flexible volume chambers.
The filtration device according to claim 1, wherein the two flexible volume chambers are positioned at opposing ends of the filter module.
The filtration device according to claim 1, further comprising at least one additional filter module, the filter modules being connected to one or more vibration motors.
The filtration device according to claim 1, further comprising a vibration motor, the vibration motor being connected to the filter module, the vibration motor configured to provide a vibration driven dead-end filtration operation, wherein one part of the media is concentrated in the filter module and discharged at the end of the operation or intermittently.
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 chamber 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.
