Metallic and Cleanable Filters

Wedge Wire Filter

We design, manufacture, and market all kinds of wedge wire screens for industrial applications. The basic structure is the welding or annular plate made by stainless steel or other alloys. The wedge wire is welded on the supported proximate matter by metal wire resistance with a V-shaped surface. The distance between the surface grooves is accurately controlled to allow the formed filter liquor flow through the V-shaped grooves and ensure the desired particles are reserved by the accurate size of the grooves. The wedge wire screen panels allow the filter liquor to flow evenly and at low speed across the screen surface, almost eliminating screen clogging.

By using a lower through-tank velocity, the solid particle with a given size will not be sucked into your technological process or clog the outer surface of the inlet screen. Almost unlimited amounts of cleanability can be provided by backwashing. The filter cakes and filtered particles are removed by reverse flow. The wedge wire filter is an ideal solution for separating solid from liquid, medium reservation, filtration, screening, dehydration, collecting, and distribution. This makes wedge wire screens the best applications of water treatment and processing industry.

wedge wire screen suppliers

Different kinds of wedge wire filters are provided by Saifilter. According to the different flow direction of the filter liquor, the wedge wire can be made by reserve twining or conventional outer surface. According to your requirement, the wedge elements can form screen nozzle, full lateral drainage system, resin trap screen, etc. to meet a variety of separate applications. We custom-make these products according to your exact specifications and offer a relatively low cost and high-performance solution for screening applications. We are your ideal wedge wire screen suppliers.

Suitable for cylinders from 7/11"(40mm) to 60"(1524mm) with groove sizes starting from 0.02mm. It can be made into a variety of stainless steel and ELC grades as well as Alloys 400, C-276 and CB-20.

Screen Nozzle

Screen nozzleis economical and clog-free, and it is suitable for use as a collector or distributor. We can offer tapered and threaded connections that can be directly screwed into the nozzle plate. Or we can use parallel thread to make wedge-shaped wire nozzle secured to the nozzle plate by a locking nut. Whether the common baseboard or rubber sheet lining baseboard is used, a suitable solution for fixing the wedge wire nozzle will be offered.

It is usually used in water treatment processes such as ion exchange. A large number of wedge wire filter elements are uniformly fixed on the round nozzle plate at the bottom of the container. The screen nozzle will retain resin medium and uniformly collect and distribute the technological process.

The size of screen nozzle, space and quantity are crucial for the guarantee of high efficiency and low-pressure drop. In the process of ion exchange, the size of the screen nozzle slot is usually 0.2 mm. The circular design is very suitable for high-pressure applications and can completely replace the non-metal screen nozzle of the existing installation.

Screen Lateral Systems

The lateral system is well-designed and produced according to your specified design conditions, including the inner diameter of the container, volume, flow, the allowed pressure drop through the screen, the resin/medium to be reserved and the minimum opening area to be listed. Also, it can provide the uniform collection and distribution technology process.

The size of the screen is crucial to ensure there is no rein medium transfer. The screen side (based on screen or screen + drill pipeline) is dismountable, and can be designed to a flange connection and screwed nipple. Connect or weld the standard NPT threads, fabricate flanges, ANSI into one assembly to connect to the distributor and drainage head.

For header pipe lateral or hub-lateral components, all the standard pipelines can offer lateral collector. We provide comprehensive engineering assistance on the design and development of the new system and the improvement and replacement of the existing devices.

  • Hub Laterals
    • Used in sand filtration, activated carbon columns and demineralizer vessels up to eight feet in diameter
    • Often designed in a multi-tier pattern as well as angled to conform to the vessel head configuration
  • Header-Laterals
    • Designed as collectors and distributors in larger vessels
    • Units are custom designed for either side or central vessel configuration and can accommodate threaded, nozzle or pad connections

Resin Trap Screen

Resin Trap Screen/Wedge Basket

The resolution of Saifilter’s wedge wire filter can offer different series of resin trap styles to adapt all kinds of applications. The resin trap screen is designed to be placed in the shell to remove the expensive resin/medium losses while protecting your pumping devices by using flow capture medium and preventing it from travelling downstream.

According to your conditions, wedge baskets can use the combination of different profile line sizes and rabbets. The engineers will consider the entrapment, fluid viscosity, proportion, corrosion rate and pressure drop to manufacture the suitable capture filter for your applications.

If your applications are considered to be extremely harsh, we will provide the engineering design required to ensure that the wedge wire baskets deformation or collapse is not a problem. The additional supports and the atypical wire combinations will be provided to ensure the optimal results.

Reverse flow, backwash, gauges, drain connections and sight glasses can all be economically incorporated. Resin trap strainers conform to industry standard dimensions and are used through the water and process treatment industries.
