What is a Filter Nozzle

Wedge wire screen filter nozzle retains the media and also provide the means for good distribution of water and air.


This term is applied to the components which retain the media and also provide the means for good distribution of water and air (where used). Nozzles may be installed in lateral pipes or in suspended floors.

A filter nozzle has three main components, a strainer to exclude the media or packing gravel, a water control orifice, and a tailpipe with an orifice(s) to control the airflow. Nozzles may rely upon the open area of the strainer slots to provide the controlling head loss for good distribution or an independent orifice within the assembly is often preferred. Strainer slots can become partially blocked with media. This will alter the head loss across the slots. If the control orifice is within the body of the nozzle and the slots have a larger open area, there will be less affected by partially blocked slots to the head loss through the nozzle.
