A pipeline strainer is provided having a cavity, a screen assembly disposed in the cavity, the screen assembly having an open first end and an open second end and a screen axis extending from the open first end to the open second end, a fluid inlet arranged at the open first end of the screen assembly, such that the fluid inlet is open to an interior of the screen assembly, a fluid outlet adjacent the open first end of the screen assembly. The fluid outlet is open to a straining surface of the screen assembly. A fluid axis extends from the fluid inlet to the fluid outlet where the fluid axis crosses the screen axis at or near the fluid inlet.

Provided is a wash press that separates liquids and solids from a waste stream. The wash press includes a tank having a semi-cylindrical shape. The tank has an inlet at a top of the tank for receiving a waste stream, a screen disposed in a portion of a bottom of the tank to permit liquid to pass therethrough, and an outlet for permitting solid materials separated from the liquid to pass therethrough. A rotor extends through the tank for transporting and dewatering the waste material entering the tank. The rotor includes a plurality of helical flights interconnected by paddle members to permit agitating the waste material. The wash press also includes a removable cover that enables the rotor to be lifted vertically, and a removably attached screen to facilitate replacement/repair of the same.

A filter assembly, comprising an open top housing comprising an inlet and an outlet; a filtering unit configured to be positioned within the housing, the filtering unit comprising a filter; a mounting arm connected to the d housing; and a fastener actuatable for extension from the mounting arm; wherein: iv) in a first position, the mounting arm is moved away from the open top of the housing; v) in a second position, the filtering unit is positioned within the housing, the mounting arm is positioned on top of the housing, and the mounting arm secures the filter within the housing; vi) in a third position, the filter is being positioned within the housing, the mounting arm is positioned on top of the housing and connected to the housing in fluid tightness, the mounting arm secures the filter in fluid tightness within the housing; and the inlet and the outlet of the housing are opened to a flow of fluid to be filtered through the filter.

A bypass strainer valve assembly can be used for controlling the flow of a fluid. The bypass strainer valve assembly can have a valve body with a valve body inlet, a valve body outlet, and a filter chamber. A first valve element can be moveable within the valve body between a first position and a second position, and a second valve element can be moveable within the valve body between a first position and a second position. The first valve element in the first position and the second valve element in the first position can be configured to cooperatively direct fluid through the filter chamber, as the fluid flows from the valve body inlet to the valve body outlet.

A filter assembly includes a manifold having a fluid inlet and a fluid outlet and a filter housing having a filter medium provided therein. The filter medium defines an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing. The filter housing is removably attached to the manifold so as to provide a fluid flow path from the inlet into the inner filter chamber, through the filter medium into the outer chamber and out of the outlet. The filter assembly also includes a valve assembly mounted inside the manifold, and a by-pass channel defined inside the manifold between the fluid inlet and the fluid outlet. The valve assembly comprises a valve spool and a valve spring arranged in engagement with the spool to bias the spool into a first position and to compress, in response to a pressure differential across the valve spool.

A blood component collection cassette that can trap a substance where blood components coagulate by using a simple and economical configuration, and a manufacturing method of the blood component collection cassette are provided. A blood component collection cassette (28) includes a cassette main body (40) where a flow path (42) is formed and is configured to be mountable to a centrifugal separation device (14). The cassette main body (40) has a first sheet (40a) and a second sheet (40b) which are formed of a soft material. The flow path (42) is formed between the first sheet (40a) and the second sheet (40b). A filter member (60) for trapping a substance where blood components coagulate is arranged on the flow path (42) in the cassette main body (40).
