FAQ's Help you Know Better about Wedge Wire Filter

The wedge wire is made of rigid triangular wire, welded to the support rods, and then installed on the round mold. The welding process consists of welding at each point in a continuous manner using a disc to form a tubular form.

The wedge wire has a triangular shape, with different heights, widths, and radius ranges at the nose and corners. Alloy, temper, and surface requirements vary depending on the application used for the screen.

Wedge wire filter is widely used in various industries. Some of the most common end uses include water filtration, mineral processing, pulp and paper making, food processing, oil extraction, and construction applications.

The wedge wire is made of resistance welded wedge-shaped or V-shaped profiles, which are at a certain distance from the support rib. The gap between these wedges allows liquid to pass through while filtering out larger particles. Wedge wire filter has a variety of shapes and sizes, which can meet the process requirements.

Wedge wire filter consists of a surface profile and a support profile. A surface profile, usually a v-shaped wire, is wound and welded to the support profile. The distance between the surface profiles is controlled very precisely as it forms the gaps through which the filtrate flows. The flow direction is determined by the position of the V-shaped wire relative to the support profile.

Our wedge wire filters are made of wedge wire. Wedge wire is rolled and periodically welded to the support rod. Thus, providing maximum open area and strength, providing the best opportunity for filtration and overflow channels. In addition to custom specifications, we also produce a variety of profiles, support bar options.

They are used for liquid filtration in industry. Examples include pharmaceutical, food and beverage, petrochemical and chemical, wastewater treatment and backwash/cleaning systems.

It offers a low risk of clogging and a self-cleaning effect. Wedge wire filter becomes the ideal solution for separating solids from liquids, retaining media, filtering, classifying, dewatering, collecting and distributing.

Wedge wire filters are used for sewage and wastewater treatment. It ensures that solid particles are filtered out 99.99% from liquid particles in the first stage, thus increasing the solid waste removal efficiency. Since the screen has a uniform filter, solid material is easily removed without clogging. A fine flat screen is used to filter sludge, further reducing suspended solids in the treated water.

The use of wedge wire filters in the food industry varies depending on the type of food or beverage a company produces. Yet every industry will look for some similar components, including pressure resistance, efficient extraction and filtration, non-clogging and ease of maintenance.

Wedge wire filter is the preferred choice in the food industry because the precise gap size allows food to pass through evenly. Larger products remain above the surface profile and can then be easily removed, reducing workplace clogging and efficiency.

It is not only suitable for water treatment and food industry, but also used in petrochemical industry especially in chemical processing. Wedge wire filters are used not only for chemical mixing, but also for media retention, desulfurization procedures, hydrotreating processes, and other applications in the petrochemical industry.

Benefits of wedge wire filter

  1. Wedge wire filterhas a larger circulation area than other screens.
  2. Uniform filter grooves and high precision ensure efficient retention of filter media.
  3. The tiny gaps between the wedge wires create a smooth wedge-shaped cross-section, ensuring no dead ends, good clogging resistance and easy backwashing (purge).
  4. Wedge wire filters have high mechanical strength and can withstand high pressure drops.
  5. It is made of high-quality stainless steel wire, which has strong corrosion resistance and high temperature resistance, and can fully adapt to various harsh environments.
  6. It can maintain stable filtration accuracy, can be reused, and work reliably.
  7. Due to the continuous gap, there are only two contact points for the particles to potentially be trapped. This minimizes blockages and therefore reduces equipment downtime.
  8. The efficiency-enhancing design of wedge wire filters means that there is little pressure drop across the liquid. This is better for the rest of the system and allows more material to be processed.

Wedge wire filter mainly has two forms: slotted tube and flat screen. Filtration grades range from 25 to 3000 microns. It mainly has cylindrical, flat, tube, basket, cone, arc filter or other more complex shapes. Depending on the design, the filtering direction can be from outside to inside, or from inside to outside. There is also a design where the screen support rod wires are arranged vertically, while the profiled wires are helically wound on the outer surface of the structural support wires.

Wedge wire is a filter medium made from shaped wire. The surface welding wire is precisely aligned and then welded to the support rod, mainly by automatic resistance welding. Wedge wire filters are made of stainless steel or other metal materials.

Wedge wire filters are metal filtration products made of stainless steel with high mechanical properties. They are static structures that provide efficient filtering. Many different industries use wedge wire filters to solve filtering problems. They can be designed according to the working principle and geometry.

Wedge wire filter is made of stainless steel, titanium, aluminum and other alloy materials. Wedge wire filters are very effective for filtering and separating solid materials from liquids. This can be important in a variety of settings, but depending on the application, the alloys and materials required may vary.

Stainless steel wedge wire filters are popular in a range of industrial applications. Wedge wire filters are used in a variety of applications, from filtration in food and beverage companies to removing solids from wastewater.

The characteristics of wedge wire filters contribute to their ideal function in microfiltration. The wedge wire design ensures no blockages, giving you an uninterrupted production process, reducing downtime and increasing throughput.

Aluminum is inexpensive, lightweight, malleable, flexible, and resistant to corrosion. It is the most commonly used non-ferrous metal for making wire mesh. Pure aluminum is rarely used to make aluminum wire mesh. To increase the strength of aluminum and enhance some of its other properties, most aluminum is alloyed with other metals, such as copper, magnesium, zinc, or silicon, in some amount.

  1. Wedge wire filter is inherently more durable because it consists of heavier gauge wire and components than woven wire mesh. A woven wire mesh filter may not be as durable on its own, but can be given the necessary strength through additional processes such as lamination into multiple layers, or by combining it with additional support or protective structures.In the larger field of filtration, when the filter is exposed to harsh environments, both wedge wire mesh and woven wire mesh are suitable for a variety of filter media.


  1. The aperture or micron rating of wedge wire filter is usually minimum about 30 microns (.030mm). The minimum micron level of the woven wire mesh filter is about 5 microns. If very fine metal filtration is required to maintain an acceptable flow rate, the woven wire mesh filter can precisely control the size of the opening, which is not even visible to the naked eye.Both types can be made with precise openings, so both can provide very precise filtration, depending on your needs in terms of pore size.


  1. Wedge wire filter and woven wire mesh filter are usually used as surface filtration, which means that the filter cake or material accumulation filtered from the liquid is located on the surface of the filter. This makes the filter easy to clean and reuse.


While both types of media are cleanable and reusable, wedge wire filters are generally easier to clean due to their smoother surface structure than woven wire mesh filters. There is also slightly less risk of damaging the material when cleaning wedge wire filters compared to woven wire mesh filters.

Wedge wire filter is formed by V-shaped metal wire resistance welding and support rod. Our products start from high-quality precursor, and then convert it into cut and shaped. We can also perform special processing on different types of wedge wire filters according to your use area and operation field.

The continuous V-shaped trunking design allows for a reduction in the rate of water ingress by reducing the rate of scaling. The tank design can also prevent clogging, prevent sand from damaging the pump and reduce pumping costs. The high opening area of wedge wire filter allows water to enter freely, thus minimizing the pressure drop of the pump and reducing energy consumption.

Wedge wire filter is solid, high in rigidity, high in wear resistance, uniform in opening, good in filtering performance and easy to clean. It has a continuous groove made of V-shaped wire, which can improve the pumping efficiency by entering the maximum water flow.

It is a metal filter product with high mechanical properties. Many different industries use the wedge wire filter to solve the filtering problem. There are different types of wedge wire filters that can be used in most applications.

The opening ratio of the wedge wire filter can be understood as the ratio of the slot size:

F: Opening ratio

x: Width of the wedge wire

n: Slot size


Open area of wedge wire filter is a very important parameter, especially for customers who use the wedge wire filter for filtering or separation for the first time, it is more important to consider this factor.

The open area of the wedge wire filter is higher than that of the woven wire mesh. The open area of the wedge wire filter is large and the treated water flow is large. It has large opening area and small pressure loss. Reduce energy consumption while ensuring our economic efficiency.

Because the V-shaped wire of the wedge wire filter is not easy to be blocked. However, the larger the opening area of the wedge wire filter is, the better. It needs to be considered according to customer needs. High filtering accuracy, low opening area and small flow. Low filtration precision, large opening area and large flow.


Wedge wire filter adopts a unique V-shaped design. The fluid can pass through the surface of the wedge wire filter under the pressure of the pressure, the pressure gradually increases, and the filtration accuracy is also slowly improved. Finally, the solid particles will be intercepted on the surface of the filter element, and the clear liquid It will be discharged from the shell and proceed to the next process.

The distance between the v-lines is controlled very precisely as it forms the gap through which the filtrate flows. The flow direction is determined by the position of the V-shaped wire relative to the support profile. Wedge wire filters flow either from the outside to the inside or from the outside to the outside.

Depending on the direction of water flow and the way of backwashing, the wedge-shaped mesh reinforcement weaving method will also change accordingly. A variety of ingenious designs and different wedge wire filters are used to ensure efficient filtration and meet filtration requirements.
