Abstract: A fluid filtration system includes a fluid storage vessel such as a bioreactor, a filter housing including a filter element disposed therein, a pump coupled between the fluid storage vessel and the filter housing, and a flow diverter disposed between the pump and the filter housing. The pump is configured to move fluid from the fluid storage vessel through the filter element, and the flow diverter is configured for selectively directing fluid received from the pump to the first or second end of the filter housing. In a first mode of operation, the flow diverter directs flow through the filter housing in a first direction, while in a second mode of operation, the flow diverter directs flow through the filter housing in a second direction opposite the first direction.

Abstract: A filtering group comprising a connection structure having a first input coupling in communication with an input conduit and an output coupling in communication with an output conduit. Further comprising a filter body connected to the connection structure and in fluid communication with the output coupling, and a ball valve housed in the connection structure and configured to assume a first position defined as when the first input coupling is placed in fluid communication with the filter body and a second position defined as when fluid communication between the first input coupling and the filter body is interdicted. The connection structure also includes a second input coupling in communication with the supply line as an alternative to the first input coupling and oriented, with respect to the output coupling, differently from the first input coupling.

Abstract: A leak detection and response system includes a valve assembly with a housing defining an internal passageway. The valve assembly includes an internal inlet port, an internal outlet port, a valve port assembly, an external inlet port, and an external outlet port each in fluid communication with the internal passageway. The valve assembly includes a first sensor port disposed either between the external outlet port and the internal inlet port, or between the external inlet port and the internal outlet port. The valve assembly includes a first leak sensor positioned in the first sensor port for generating a signal indicating a presence of water. The valve assembly includes a controller configured to receive the signal from the first leak sensor, and control the valve assembly to align the valve port assembly to block water flow from the external inlet port.

Abstract: 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.
