Wedge wire screen–the best filter strainer for Industrial Wastewater Treatment and Filtration

The water treatment industry has long faced numerous challenges such as water pollution, water scarcity, and climate change. These challenges have created a demand for technology and solutions to enhance the sustainability and efficiency of water resources. Wedge wire screens play an indispensable role in various areas of water treatment, such as filtration and separation, solid-liquid separation, flow control, and sludge treatment. These products efficiently facilitate water filtration, separation, and flow control, playing a crucial role in ensuring the sustainable utilization of water resources and environmental protection.

Groundwater testing: Wedge wire can filter out sand, gravel and other debris to prevent groundwater contamination.

Seawater desalination: As a part of pre-filter systems, wedge wire can effectively remove impurities and particles from seawater.

Municipal water treatment: Wedge wire is used to separate solid impurities from water to improve the quality of municipal water.

Fish protection barrier: Wedge wire protects fish and other aquatic organisms from being drawn into the water intake system.

Sludge treatment: Wedge wire can efficiently separate water and solid sludge and facilitates treatment and dewatering of sludge.

We supply various wedge wire screen filter strainers used in wastewater treatment industries. 

1. Filter Nozzle - Precision Filtration at the Final Stage

Application: Tertiary filtration, media retention in sand and activated carbon filters

Filter nozzles are compact wedge wire elements mounted at the base of filter vessels. In wastewater treatment, they prevent media loss and ensure even flow distribution during both filtration and backwash cycles. 

2. Wedge Wire Water Distributor - Uniform Flow for High Efficiency

Application: Flow regulation in trickling filters, aeration basins, and clarifiers

Water distributors made from wedge wire offer uniform flow distribution across the entire treatment surface. In processes like biological treatment or sedimentation, uneven flow can lead to process inefficiencies and reduced performance.

3. Wedge Wire Basket - Robust Support for Coarse Solids Separation

Application: Pre-screening of influent wastewater, grit, and sludge handling

Wedge wire baskets are cylindrical or conical filters designed to intercept large solids before they enter downstream treatment units. Their self-cleaning design and high load capacity make them ideal for the initial stages of wastewater processing, protecting pumps and fine screens from damage and extending their service life.

4. Resin Trap - Protection Against Resin and Media Loss

Application: Safeguarding downstream equipment in ion exchange and tertiary polishing

Resin traps are vital in preventing costly media loss from ion exchange systems or polishing filters. 

5. Intake Screen - The First Line of Defense in Water Inlet Systems

Application: Surface water intake for municipal and industrial wastewater facilities

Wedge wire intake screens are positioned at the point where water enters the treatment plant, filtering out large debris such as leaves, sticks, and aquatic life. Designed for high-capacity, low-maintenance operation, these screens protect treatment systems and ensure compliance with environmental regulations, including fish protection standards.

6. Sieve Bend Screen - Gravity-Driven Solids Separation

Application: Pre-treatment and primary screening in municipal wastewater

Sieve bend screens, also known as curved screens, are gravity-fed systems used to remove fine solids before biological treatment stages. Wastewater flows over a curved wedge wire panel, and solids are separated by gravity as water passes through the screen. This simple yet efficient method reduces load on secondary treatment systems and lowers energy usage.

7. Wedge Wire Panel - Modular Screening Versatility

Application: Custom screening in channels, tanks, and overflow systems

Flat wedge wire panels are used as modular screening elements in various parts of a wastewater facility.

8. Coanda Screen - High-Capacity Screening Under Open Channel Flow

Application: Stormwater overflow, high-volume screening stations

Coanda screens are engineered to utilize the Coanda effect, allowing water to adhere to a curved wedge wire surface while solids slide off. They are ideal for handling variable flow rates and large debris loads, especially in overflow systems and stormwater treatment applications.

9. Rotary Drum Screen - Continuous Automatic Screening

Application: Fine solids removal in primary and secondary treatment

Rotary drum screens are rotating cylindrical wedge wire filters that remove fine particles from wastewater. As water enters the drum, solids are trapped on the screen surface and removed by a cleaning mechanism. Common in municipal and industrial plants, rotary drum screens offer continuous, automated filtration with minimal operator intervention, enhancing overall system efficiency.

Wedge wire screen products have become indispensable in modern wastewater treatment systems, offering unmatched performance, longevity, and customization. Whether you're designing a new facility or upgrading an existing one, integrating wedge wire components such as filter nozzles, water distributors, baskets, resin traps, and rotary drum screens will enhance reliability and efficiency.
