There is provided a film separation device 1 equipped with a treatment tank 2 receiving a liquid to be treated, a film unit 3 to be immersed in the liquid to be treated, and a guide mechanism 4. The guide mechanism 4 is composed of holding sections 14 and a guide section 15. The holding sections 14 are provided on a side section of a film cassette 5 constituting the film unit 3, and the guide section 15 is fixed to the treatment tank 2. The guide section 15 has a tank-wall fixed section 15a, an upper extension section 15b, a held section 15c, a lower extension section 15d, and a tank-bottom fixed section 15e. When fixing the film unit 3 to the treatment tank 2, the holding sections 14 are fitted to the held section 15c, thereby guiding the film unit 3 to a predetermined position in the treatment tank 2.

Provided are a plate-type filter module for water treatment and a filter assembly for water treatment comprising the same. The plate-type filter module for water treatment according to one embodiment of the present invention comprises: a plurality of filter units having a predetermined area and formed in a plate shape; a block frame to which the plurality of filter units is engaged so that the filter units are kept parallel to each other; and a collecting/receiving tube fixed on one side of the block frame and including a plurality of first fittings respectively connected to the plurality of the filter units to allow filtered water produced in the filter units to be introduced thereinto and at least one second fitting for discharging the filtered water introduced through the plurality of first fittings to the outside.

The present invention relates to separation methods and systems for converting high concentrations of animal wastes into useful products, wherein the separation of the desired useful products is conducted with a cross-flow filtration system having the ability to the separate desired useful energy and/or products from both viscous and non-viscous medium.

The present disclosure provides instruments, modules and methods for improved detection of edited cells following nucleic acid-guided nuclease genome editing. The disclosure provides improved automated instruments that perform methodsincluding high throughput methodsfor screening cells that have been subjected to editing and identifying cells that have been properly edited.

A membrane device is presented that can used for a wide range of applications from once-through filtration, crossflow filtration, molecular separation, gas/liquid absorption or reaction, gas dispersion into liquid, and degassing of liquid. The device comprises a thin flat sheet membrane that allows certain fluid or molecules go through while blocking others. The membrane sheet is fixed on a supporting structure with mini channel on two sides of the membrane for respective feed and sweep flows. The membrane sheet is sealed with gaskets with two cover plates that the membrane sheet can be replaced or cleaned. The cover plate provides connection ports to connect the feed fluid to the feed channels on one membrane surface and to connect the sweep fluid to the sweep channels on the other surface of the membrane.

A membrane device and separation process are presented to enable removal of water from water-containing mixtures at high throughput and high energy efficiency. The membrane device is made of thin H.sub.2O-selective molecular sieve membrane sheets with small feed channels and small permeate channels. The thin membrane sheet provides H.sub.2O-molecular specificity and allows H.sub.2O molecule to permeate through while blocking the other molecules. The membrane device provides large membrane area per unit volume and reduces mass transfer and flow resistance. Water is removed from the mixture by flowing the water-containing mixture through the feed channels of the device at a pressure above atmospheric pressure and removing the permeated water vapor from the permeate channels in the device under vacuum.

The present disclosure relates to a non-invasive, non-gravitationally dependent, pressurized method for the rapid selective extraction, volume expansion, and reclamation of medication and medication metabolites (including but not limited to naturally occurring or engineered hormones, chemicals, antibodies, enzymes, lipids, proteins or pharmaceutical products) from urine. The disclosure further relates to methods for reclamation of medication from urine in a pressurized system and methods of using the medication reclaimed from that urine.
