Wedge Wire Flat Screen Panel: Providing Effective Solid-Liquid Filtration and Separation

In many industrial sectors, such as water treatment, food processing, mining, pulp and paper, pharmaceuticals, and petrochemicals, the wedge wire flat screen panel has become an essential technology for solid-liquid filtration and separation. Its blend of precision, durability, and clog-resistant design makes it a go-to solution for operators seeking consistent performance and low maintenance.

What Is a Wedge Wire Flat Screen Panel?

A wedge wire flat screen panel is constructed by welding V-shaped (wedge) wires onto support rods, forming continuous, precise slots through which liquid can pass while solids are retained. This clever triangular wire profile not only delivers accurate, custom slot sizing but also dramatically reduces the risk of clogging, minimizing pressure drop, and allowing easy backflushing.

Wedge Wire Panel Key Advantages in Solid-Liquid Filtration&Separation

• High-Precision Filtration

Uniform, tailored slot openings allow accurate separation of solids from liquids - essential for clarity in juice, beverage, pharmaceutical suspensions, and wastewater.

• Non-Clogging, Self‑Cleaning Design

The V-shaped wire ensures minimal contact points with solids; any trapped particles can be dislodged via backwash for continuous operation.

• Robust and Long‑Lasting

Made from stainless steel (typically SS304, SS316L) or exotic alloys, these panels resist corrosion, wear, and high pressures, offering durability unmatched by traditional meshes or cloths.

• Low Maintenance & Easy Cleaning

Their smooth surface and structural rigidity make manual cleaning or automated backflushing more effective and efficient.

• High Throughput with Low Energy Use

The wide open area (30–60%), combined with low clogging, ensures optimal flow rates and lower pumping energy.

• Materials: Stainless steels (304 and 316L), duplex, titanium, and Hastelloy for corrosive and caustic environments.

• Shapes & mounting: Custom flat, inclined, or part of centrifuge baskets; equipped with frames and installation features.

• Support rods: Variants include round, square, V-shape, flat bar, or water-drop cross‑sections for structural needs.

Choosing the Right Wedge Wire Screen Flat Panel

When selecting a wedge wire flat screen panel, consider:

• Filtration target: particle size and throughput requirements

• Operational environment: corrosive, temperature, pressure load

• Cleaning method: backwash needs and downtime tolerance

• Longevity & cost: upfront vs. lifecycle cost savings
