The present invention relates to a device (1) for the filtration of a fluid circulating in a plumbing and heating system, comprising a body (2) of the device defining therein a filtration chamber (3) and equipped with: filtration members (40), to perform a filtration of the fluid passing through the filtration chamber (3), comprising a filtering element (41) which divides the filtration chamber into a first (8) and a second half-chamber (9); an inlet/outlet interface (10) having a first inlet/outlet opening (11), in communication with the first half-chamber, and a second inlet/outlet opening (12), in communication with the second half-chamber. The device comprises a connection module (30) which can be mounted on the body of the device and comprising: a first inlet/outlet conduit (31) and a second inlet/outlet conduit (32), configured to be associated with respective pipes of a heating system; a connection interface (33) that can be selectively associated with the inlet/outlet interface of the body of the device; a first passage section (34), defined on a portion of the connection interface and in fluid communication with the first inlet/outlet conduit; a second passage section (35), defined on a respective portion of the connection interface and in fluid communication with the second inlet/outlet conduit. The connection module (30) is configured to be selectively mounted on the body (2) of the device according to a plurality of different operative configurations.

The present disclosure belongs to the technical field of water treatment valve bodies, so as to solve the technical problem that an effective area of a water inlet and outlet hole inside a valve body cannot be simply and effectively reach an effective area of a water inlet and outlet pipe orifice outside the valve body. Based on this, a multifunctional water treatment filter valve is provided, including a valve body, a movable valve plate, a fixed valve plate, and a driving device. The fixed valve plate is fixedly mounted in the valve body; the movable valve plate and the fixed valve plate are in rotatable fit in the valve body; and a side wall of the valve body is provided with a water inlet, a water outlet, and a drainage opening.

A control system for a water filter assembly comprising a filter having an RFID tag and an RFID sensor to generate a RFID signal containing data related to the filter. A valve assembly moves between a shut off position, an operational position directing the flowpath of the water supply through the filter, and a bypass position. A controller communicate with a lawn irrigation system to determine if the irrigation system is operative. When operative, the controller has the valve assembly switch to the bypass position. The controller also receives the RFID signal to verify if the filter is proper. The controller also receives a leak signal from a leak sensor and has the valve assembly automatically switch to the shut off position if a leak occurs. The controller can name the leak sensor with a location and indicate battery life of the leak sensor.

A backwash filtration system comprising a backwash discharge port, a sedimentation collection and separation system, and a final filtration chamber. The backwash discharge port is coupled with a pool filter system and is configured to pass backwashed water from the pool filter system to the sedimentation collection and separation system. The sedimentation collection and separation system has a plurality of sedimentation chambers that are vertically stacked and a plurality of baffles configured to reduce the migration of sediment within the sedimentation chambers. A path for water flow passes down sequentially through each of the sedimentation chambers. The final filtration chamber receives the backwashed water from the sedimentation collection and separation system, filters the backwashed water through a final filtration medium, and passes the filtered water to a water return line of the pool filter system or to a pool of water.

A swimming pool backwash filtration device for filtering backwash includes a house. The house has an interior defining a space for a filter to be stored within. The house has an inlet surface and an outlet surface where the inlet surface has an inlet conduit. A y-valve comprises an intake conduit and a pair of exit conduits. The intake conduit is in fluid communication with a pump and a debris filter of a swimming pool. The pair of exit conduits includes a backwash exit conduit and a pool exit conduit. The pool exit conduit is in fluid communication with the inlet conduit of the house.

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 modular device for a fixed arrangement and interconnection of individual separation units and/or first functional units for performing one or more unit operations in a biotechnological process. The modular device includes a plurality of distributor caps provided for attachment to the separation units and/or first functional units. The distributor caps each have: a fluid distribution mechanism having a working connection and at least two supply or discharge connections, wherein the fluid distribution mechanism can assume at least two defined switching positions; connection mechanisms for establishing a flow communication between a fluid inlet or outlet of the separation unit or the first functional unit and the working connection of the fluid distribution mechanism; coupling mechanisms for establishing a rigid mechanical coupling and a flow communication with an adjacent distributor cap; and an interface for changing the switching positions of the fluid distribution mechanism.

A water filtration system is provided. The system may include a connector and a filter configured to be mounted in the connector. The connector may include a connector body, a connector inner core, a connector core baffle, a connector body water inlet of the connector body, and a connector body water outlet of the connector body. The water filtration system may have a filtering configuration and a bypass configuration. In the filtering configuration, the water filtration system may be configured to direct water through the filter. In the bypass configuration, the water filtration system may be configured to direct water out the connector body water outlet without passage through the filter. The water filtration system may be in the filtering configuration when the filter is fully mounted in the connector. The water filtration system may be in the bypass configuration when the filter is not fully mounted in the connector.
