Patent attributes
A fluid strainer assembly and a method of reducing an amount of fluid used during a cleaning cycle of the fluid strainer assembly including: a body defining a chamber; a screen positioned within the chamber; and a backwash port associated with an internal portion of the screen and rotatable about a central axis to cause a tangential flow and backflow of backwash fluid in order to dislodge and remove foreign material collected on the inner surface of the screen to flow into the backwash port and exit out a discharge outlet and backwash pipe, wherein the backwash port is configured such that the area of draw is determined by the equation: i) CS×1.875×1.5≥A; and ii) A≥CS of backwash pipe, where CS represents the internal transverse area of the backwash pipe and A represents the area of draw of the backwash port.
