Embodiments of a fluid filtration system constructed in accordance with principles of the present disclosure can be used to automatically condition the single use filter for efficient use thereof. For example, in embodiments, the fluid filtration system can include a filter conditioning program containing at least one of a filter priming module, a filter flushing module, and a filter pressurizing module.

A filter assembly and a method of operating the same to detect water leaks are provided. The filter assembly includes a filter housing for receiving a filter cartridge and at least partially defining a drain trough positioned below the filter cartridge for collecting leaked water. A light source is positioned proximate the drain trough for directing light through the drain trough and a light sensor is positioned proximate the drain trough for sensing the light directed through the drain trough. A controller uses the light sensor to monitor the light generated by the light source and determines that a leak exists when an intensity of sensed light is reduced by the leaked water.

Disclosed is a filter assembly capable of adjusting elimination of solid materials using a flow-variable bypass flow path. The filter assembly includes a filter portion (100) which includes a cover portion (110) formed on top to have a shape in which a bypass flow pipe (112) and a water discharge pipe (113) sequentially surrounds a perimeter of a vertically protruding original water inflow pipe (111) in a stepped structure and accommodates a filter body therein and a filter cartridge header (200) in which the cover portion (110) of the filter portion (100) is accommodated therebelow and which includes a bypass flow rate control unit (300) capable of adjusting an inflow amount of original water flowing into the bypass flow pipe (112).

A batch-type filtering apparatus includes: a first flow path; a second flow path configured to communicate with the first flow path; a third flow path configured to communicate with the first flow path; a fourth flow path configured to communicate with each of the second flow path and the third flow path; an external port configured to communicate with each of the third flow path and the fourth flow path; a first direction switching valve configured to allow at least two from among the first flow path, the second flow path, and the third flow path to communicate with each other; a second direction switching valve configured to allow at least two from among the third flow path, the fourth flow path, and the external port to communicate with each other; and a flow cell.

A filtering device includes a water pump, a filter cartridge, and a communicating tube for coupling the water pump with the filter cartridge. The filtering device further includes a flow switch attached to the communicating tube and configured to change switching states in response to a water flow rate in the communicating tube being lower than a predetermined value. The filtering device further includes a reminding device operably connected to the water flow switch. The reminding device generates a reminder signal when the state of the water flow indicates that the flow rate of the water in the communicating tube is lower than the predetermined value. The control system includes a control panel for the filtering pump, a central control system, and a filtration detecting system. The control panel is connected to the central control system and the central control system is connected to the filtration detecting system.

A disposable filter including an integrated sensor is provided for filtering a working fluid and monitoring the working fluid and/or the performance of the filter. The filter includes a housing with an inlet and an outlet with filter media disposed within the housing in a flow path defined between the inlet and the outlet. The integrated sensor is disposed within the housing, where the integrated sensor monitors a characteristic of the working fluid or other performance characteristic of the filter. The sensor assembly may include a communication module. The sensor assembly may include a RF tank circuit with a capacitor plate, which may be disposed adjacent a bypass structure that is disposed adjacent the outlet. Movement of a moveable part of the bypass structure in response to a pressure buildup will cause a shift in a resonant frequency of the tank circuit.

A filter cartridge includes a casing. A filter medium is disposed within the casing. A radio-frequency identification, RFID, tag is positioned on the casing. A leak detection pad is positioned on the casing. The RFID tag is in communication with the leak detection pad. The RFID tag is configured to transmit a leak detection signal in response to a liquid at the leak detection pad.

A filter assembly and a method of operating the same to detect water leaks are provided. The filter assembly includes a filter housing for receiving a filter cartridge and at least partially defining a drain trough positioned below the filter cartridge for collecting leaked water. A light source is positioned proximate the drain trough for directing light through the drain trough and a light sensor positioned proximate the drain trough for sensing the light directed through the drain trough. A controller uses the light sensor to monitor the light generated by the light source and determines that a leak exists when an intensity of sensed light is reduced by the leaked water.

A passive fluid treatment assembly is provided including a passive treatment body defining a primary flow path and a liquid treatment path. The liquid treatment path bypasses a portion of the primary flow path and enters a treatment enclosure through a high pressure port. The fluid entering the high pressure port is treated by a treatment media in the treatment enclosure and exits through a low pressure port into a mixing chamber where it is remixed with the fluid in the primary flow path. A one-way valve is operably coupled to an outlet of the high pressure port for preventing the flow of treated fluid from exiting the treatment enclosure through the high pressure port.
