The invention concerns a filtration assembly for microbiological testing and a method of using the filtration assembly for that purpose. The filtration assembly (1) comprises a ring-like membrane support (10) holding a filtration membrane (11), a cylindrical reservoir (20) of which opposite axial ends have openings and one axial opening is removably and fluid-tightly attachable to the membrane support (10) to define a sample volume adjacent to the filtration membrane (11) on one axial side of the membrane support (10); and a lid device (40) removably and fluid tightly attachable to the other axial opening of the reservoir (20) to close the opening. Further, the lid device (40) is removably and fluid tightly attachable to the membrane support (10) so as to seal the one axial side of the membrane support (10) from the environment.

A method including determining a first value associated with a first component of a water filtration system using a first sensor of the water filtration system, determining whether the first component is degraded based on the first value, and in response to determining that the first component is degraded, initiating a shipment of a replacement component.

In an embodiment, a modular water filtration system includes a magazine and a base. The magazine includes a plurality of cartridge receptacles, a magazine input water valve, and a magazine output valve, where a first cartridge receptacle is coupled between the magazine input water valve and the magazine output valve. The base includes a first fitting configured to receive input water, a second fitting configured to provide drinking water, a base input water valve configured to be coupled to the magazine input water valve, a first solenoid valve having a water path coupled between the first fitting and the base input water valve, a base first valve configured to be coupled to the magazine output valve, and a first switch.

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 methods—including high throughput methods—for screening cells that have been subjected to editing and identifying cells that have been properly edited.

The present invention provides compact spiral-wound filter elements having cassette-like performance. The invention further provides filtration systems (e.g., TFF systems) and processes (e.g., SPTFF processes) employing compact spiral-wound filter elements having cassette-like performance.

Algae harvesting and cultivating systems and methods for producing high concentrations of algae product with minimal energy. In an embodiment, a dead-end filtration system and method includes at least one tank and a plurality hollow fiber membranes positioned in the at least one tank. An algae medium is pulled through the hollow fiber membranes such that a retentate and a permeate are produced.

The present invention relates to a system and process for treating a feedwater wherein the system includes at least one RO or nanofiltration unit that receives a feed under high pressure and produces a concentrate that is directed to and held at low pressure in a concentrate accumulator. Generally the permeate or the inlet feedwater is maintained at a constant flow rate. Periodically the system is switched from a mode 1 or normal operating process to a mode 2 where the concentrate is drained from the concentrate accumulator. However, in mode 2, the feedwater is still directed into the system and through the RO or nanofiltration unit which produces the permeate and the concentrate.

The present application provides a water tank assembly for water purification and a water purification system. The water tank assembly includes: a first water tank, a water inlet guide tube, a water inlet control assembly, a second water tank and a water outlet guide tube. Parameters of the water tank assembly includes a first liquid volume. The first liquid volume is greater than the initiation liquid volume and less than or equal to a level-difference liquid volume. According to the present disclosure, the first cup of water is diluted rapidly to reach the direct-drinking water, ensuring freshness of the direct-drinking water, and allowing the second water tank to take water from the first tank quickly for at least twice.

A Vehicle Wash Reverse Osmosis System is provided,
