Wedge Wire Industrial Screens: An Overview
Industrial processes are increasingly demanding when it comes to filtration, separation, and retention. When conventional screening methods fall short—whether due to unique technical requirements, harsh environments, or specialized media—wedge wire screens offer a high-performance, customizable solution.
What is a Wedge Wire Industrial Screen?
Wedge wire screens—also known as profile wire or V-wire screens—are fabricated by helically wrapping a V-shaped wire around a series of longitudinal support rods. The intersection of the wire and rods is resistance welded to create a rigid, durable, and non-clogging surface ideal for filtration and separation applications. The V-shaped design minimizes the risk of clogging while ensuring precise slot openings, ranging from 0.002 inches and up, depending on the application.
These screens are available in a wide range of stainless steels and corrosion-resistant alloys such as 304, 316L, 2507 Duplex, and Hastelloy, making them suitable for aggressive chemical environments. Their strength-to-weight ratio and dimensional stability under high pressure and temperature loads make them indispensable across multiple sectors including: water and wastewater treatment, food and beverage processing, petrochemical refining, pulp and paper manufacturing, mineral recovery, and power generation.
Types of Wedge Wire Industrial Screens
Catalyst Bed Support Grids
AMACS Catalyst Support Grids are engineered for high-load applications in fixed-bed reactors and pressure vessels. These grids offer high open area and near-zero clogging potential while maintaining structural integrity under thermal cycling and pressure variations. Designed in modular segments to fit through vessel manways, these systems can include distributor laterals, inlet baskets, and backwash-enabled outlet collectors.
Hub and Header Laterals
Used in filtration, ion exchange, and underdrain systems, AMACS hub and header laterals ensure uniform flow distribution. Lateral arms can be customized for side, top, or bottom inlet configurations. Internal backwash capabilities help maintain performance with minimal maintenance. Typical applications include filtration for demineralizers, condensate polishers, and sand filters in municipal and industrial water systems.
Wedge Wire Nozzles and Strainers
Designed for precision flow control and media retention, AMACS wedge wire nozzles are available with varying thread types, flow rates, and materials. These are commonly installed in underdrain distributors and filter beds for water softening, sand filtration, and activated carbon systems. High open-area design (up to 60%) minimizes pressure drop while maximizing media usage and efficiency.
Sieve Bend and Flat Screens
Sieve bend screens from AMACS deliver high-capacity dewatering with self-cleaning, non-blinding performance. Typically used in slurry separation, pulp and paper effluent, and aggregate processing, these screens harness gravity and flow direction to separate solids from liquids efficiently. Constructed from 304 or 316 stainless steel, they provide exceptional wear resistance and long service life.
Resin Trap Screens
Installed inline to prevent media loss, AMACS resin traps provide a last line of defense in systems using ion exchange or specialty resins. Designed to retain media down to sub-millimeter sizes without impeding system flow, these traps can be configured in both vertical and horizontal orientations, with optional flanged or threaded ends for easy integration.
