Description of the Wedge Wire Screens


    Wedge Wire Screens are manufactured by wrapping a profile wire cylindrically around longitudinal placed support rods. All wires and rods are resistance welded at each point of contact. The numerous combinations of wire profiles, support rods, flow direction and wide range of slots (fixed or variable) allow UBO to design screens according your exact technical specification. We manufacture wedge wire screens for a variety of industries including water well production, water treatment, food and beverage, oil and gas, pulp and paper, mineral and aggregate processing, refining and petrochemical.

    UBO wedge wire screen are available in diameters ranging from less than 1” up to 30” in diameter. The gap or slot openings are selected based on the customer’s requirements. With a variety of wire shapes and sizes available, the correct combination is available to meet the open area and strength requirements for the particular application. As a custom fabrication ship, we are able to supply a variety of fittings for well screens. Typical requests include end plates, weld rings, flush joints and NPT threaded joints on these screens.

Some varieties of the wedge wire screen 


1. Water Well Screen

UBO is a vertically integrated mesh producer. It controls every step of the manufacturing process from knitting the wire through mesh assembly and custom fabrication of related supports, grids and housings for your mist eliminators or other wire based column process internals.

2. Intake Screens

UBO wedge wire intake screens are designed to completely meet customer specifications. Whether a single drum or a double drum (like a T-Intake Screen) is required, these screens are designed for a low uniform velocity through the consistently spaced, high open area and smooth screen surface. The exact slot opening is selected to achieve optimum performance for the pond, lake, ocean or river service. An air burst system will be designed and incorporated when customer’s specification require periodic cleaning of the screen.

3. Underdrains

UBO wedge wire type underdrain screens are fabricated with flat high surface open area for the retention of costly media in down flow processes. Typically, underdrain screens are made either with a surface finished plate flange or with a framing bar to be welded directly to the vessel wall.

4. Digester Baskets

UBO wedge wire digester baskets are designed and manufactured to meet customer performance requirements and other detailed specifications.

5. Dewatering Screens

Dewatering screens are also known as sieve bend or curved screens. UBO wedge wire type dewatering screens are designed to maximize capacity by using gravity and cross flow against the curved screen surface for removal of solids from a liquid process stream. Dewatering screens can be fabricated with most any slot opening, screen width or angle and are routinely mounted to a boxed style housing. Applications for dewatering screens include wastewater treatment, sewage treatment, agriculture, mining and food wastewater processing.
Wedge wire screens are also particularly well matched to the requirements of high capacity filtration since they are self-cleaning, durable and reusable. Sieve bend (or curved) screens orient the wedge wires perpendicular to the flow direction which allows water to drop through screen and be collected as wastewater while the angle and flow forces the solids (or branches) to slide over the smooth screen. This product is effective in wastewater treatment, dewatering systems and other similar solid separation applications as well. Flat screen panels are used in a similar application as sieve bend and in shakers for sewage separation systems.

6. Sieve Bend and Flat Screens

Wedge wire screens are particularly well matched to the requirements of high capacity filtration. These screens are self-cleaning, durable and reusable. Sieve bend (or curve screens) have the wedge wires oriented perpendicular to the flow direction which allows water to pass through screen to be collected as wastewater while the angle and flow allows the solids or branches to slide over the screen’s smooth surface. These screens are effective in wastewater treatments, dewatering systems and other water-solid separation applications as well. Flat screen panels are used in a similar application as sieve bend screens as well as in shakers for sewage separation systems.

7. Rotary Drum Screens

UBO rotary wedge wire screen cylinders are custom made to meet customer specified flow rate, slot opening, and direction of flow. The outside diameter (or inside diameter) and length of the cylinder are fabricated to ensure a match with other associated equipment. These screens can be rerolled in the helical or axial direction to allow flow from the inside out for dewatering filtration services in many industries such as food processing, agriculture, mining, paper pulp and water treatment.

8. Hub and Header Laterals

Hub laterals are designed for vessels with elliptical heads. They enable the system to collect completely to the bottom of the vessel. Header laterals are suited for flat bottom vessel distributor or collector applications. These systems can be designed to accommodate side, center, top or bottom inlet piping. Integral backwash systems can be designed for any hub or header lateral for a fast, effective and efficient cleaning of the screen. Laterals are usually connected to the hub or header with either flanges or threaded fittings. Systems are designed for effective liquid or solid retention in a wide range of applications including exchangers, clay or sand filtration, carbon towers and power plants with water systems. Our experienced engineering group designs each system to provide even distribution or collection across the entire cross-sectional area of the vessel.
