A fluid flow control device includes a valve body defining an inlet, an outlet, and a fluid flow path extending therebetween, a valve seat ring coupled to the body that defines an orifice through which the fluid flow path passes, a cage coupled to the body that defines an interior bore, a control element slidably disposed within the interior bore of the cage, and a particle catcher at least partially disposed within an interior bore of the control element. The particle catcher includes a particle catcher body that defines an inner flow path and at least one particle catcher passage through which the fluid flow path passes. An outer surface of the particle catcher and an inner surface of the control element form a particle catching portion. The at least one particle catcher passage directs the fluid flow path downwardly into the particle catching portion.

A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portionseach communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough.

A blood processing filter comprises an inlet-side flexible container and an outlet-side flexible container that sandwich a filter element, an inlet port, and an outlet port, the filter further comprising: a flow path securing sheet; a first seal portion; and a second seal portion, wherein the flow path securing sheet includes a pair of ribs disposed opposite to each other with the outlet port interposed therebetween, and a slit formed inside of the pair of ribs, and diffusing openings that are disposed outside of the pair of ribs and continuously open from the ribs to the lateral portions of the first seal portion.

A drainage system for a galley of a vehicle includes a sink that is configured to receive a colored liquid. A liquid pigment remover is in fluid communication with the sink. The liquid pigment remover is configured to remove color from the liquid. A drain is in fluid communication with the liquid coloration. The drain is configured to pass the liquid overboard from the vehicle after the color is removed (or partially removed) from the liquid by the liquid pigment remover. The drainage system may also include a strainer that is configured to strain particulates from the liquid before the liquid passes overboard out of the vehicle.

A method of filtering fluid for injection into an injection well comprises detecting a fluid pressure in a conduit upstream of an actuator valve, verifying that the fluid pressure is within an operating pressure range, opening an actuator valve based on the verifying, receiving a fluid having suspended solids within a filter assembly in response to opening the actuator valve, actuating a pump in fluid communication with the filter assembly based on receiving the fluid within the filter assembly, and separating at least a portion of the suspended solids in the fluid within the filter assembly.

A method of filtering a fluid for injection into an injection well comprises opening an actuator valve, actuating a pump in fluid communication with the actuator valve, receiving a fluid comprising solids within a filter assembly, where the pump is in fluid communication with the filter assembly, separating at least a portion of the suspended solids in the fluid within the filter assembly, ceasing separation of the suspended solids from the fluid, initiating a cleaning cycle for the filter assembly after ceasing separation of the suspended solids, washing at least the portion of the suspended solids from the filter assembly into a solids collection vessel using a cleaning fluid after initiating the cleaning cycle, and resuming separation of the suspended solids from the fluid after washing at least the portion of the suspended solids from the filter assembly.
