Nozzle Screen for False Bottom Filter

Media Retention Nozzle,or Wedge wire screen nozzle , in stainless steel 316, for high flow rates to be placed on plate or false bottom filters.

Distributors with lateral pipes equipped with wedge wire nozzles or orifices are the simplest systems in Granular Media Filters.

Johnson Media Retention Nozzles are used for the retention of granular media in water treatment equipment. These media can be of any type, such as: activated carbon, silica sand, ion exchange resins, green sand, MTM, Birm, pyrolusite, among others.

In addition to the retention function, the micro-slotted nozzles provide good drainage and adequate flow distribution, both in equipment working under pressure and in those working by gravity.

The Johnson type element through which the fluid flows, has a “V” shaped cut, with the most closed part towards the outside of the nozzle. This design prevents clogging.

The microslot is continuous and has a total flow area of approximately twice the cross-sectional area of the connection nipple. This means that the microslot does not constitute a restriction to flow and, therefore, causes minimal pressure drop.
