How is Filter Nozzle Mounting Methods?

Four options for steel plate underdrains: (All require a gasket for air scour applications)

First and the most time consuming, holes drilled in the plate are tapped and nozzles threaded into the holes.

Second, plate holes may be drilled, nozzles inserted, and a backup nut threaded on from the underside which must be accessible.

Third, a Type MUZ locking nut and washer will permanently secure a nozzle from the underside.

Fourth and usually recommendation, is to use an expanding ring. The gasket is mounted onto the expanding ring and placed into the hole location. As the nozzle is threaded into the expanding ring, its legs secure the nozzle in place like a toggle bolt. These components may all be easily installed from the top side of the underdrain plate.

They are manufactured in accordance to customer flow requirements in almost any alloy.

They can be designed for filtration or treatment systems to permit more effective use of the treatment media.

Because of their non-clogging design strainer are effective in a wide range of water treatment and other industrial applications.

Common applications include under drain media retention elements or flow distributors in demineralizers and water softeners in pressure and gravity sand filters.

Strainers can be also used as collectors at the bottom of the vessels by installing a number of strainers uniformly across a tray plate .

The combination of high open area and a non-plugging slot design makes this nozzle/collector application pupilar.
