Filter nozzles are important components of ion exchange units, media filters, sand filters, carbon strip vessels, carbon towers, clay filters, and in many water and waste water treatment applications, which can have multiple tiers of wedge wire screen laterals.
     Filter nozzles are available for larger diameter filters. Wedge wire screen laterals make excellent collectors. A perforated pipe distributor can be added to improve back-wash distribution and increase strength.
    Wedge Wire screen cylinders can be designed with slot openings and wires running radially on the outside for flow from outside to inside. Or they can be positioned axially on the inside of the cylinder for flow from inside to outside.
   Economical wedge wire screen nozzles can be used as collectors in false bottom (tube
sheet) vessel installations.
