A wedge wire spray nozzle is a filtration and water distribution device made of high-quality stainless steel. It features avee-shaped wire profile to prevent clogging and enhance flow efficiency. Mounted on bottom underdrain plates, these filter nozzles evenly distribute water or other fluids during filtration and backwashing.
Key characteristics include:
- Material: Primarily made from 304, 316L, or 904L stainless steel, ensuring corrosion resistance and longevity.
- Design: Features precise slots that prevent media leakage while maintaining consistent flow.
- Threaded Connection: Typically designed with male or female threads for secure mounting on underdrain plates.

Benefits of Bottom Underdrain Plate Wedge Wire Spray Nozzles
The bottom underdrain plate is the foundation of many filtration systems, providing structural support and a base for water distribution. Pairing this component with wedge wire nozzles enhances its efficiency due to the nozzles’ unique features:
1. Clogging Resistance
The vee-shaped wire design prevents blockages caused by suspended solids or filtration media.
2. Customizable Design
Nozzles can be tailored to meet specific slot sizes, lengths, and connection types.
3. Durability and Longevity
Made from stainless steel, these nozzles are highly resistant to wear, corrosion, and harsh chemicals.
4. Easy Installation and Maintenance
Threaded or flanged connections allow quick assembly and disassembly, saving time during system maintenance.
5. Improved Filtration Efficiency
The precise slot openings ensure uniform water flow, enhancing overall system performance.

Industrial Applications Across Bottom Underdrain Plate Wedge Wire Spray Nozzles
- Installed inside the support plate of the condensation tower, used for gas-solid separation.
- Installed in ion exchange mixed beds to retain media while allowing treated liquid to pass through.
- Used as drainage media retention elements, flow distributors in desalters, and water softeners in sand filters.
- When evenly mounted on the bottom of a container or vessel, the wedge wire nozzle can also be used as a collector.
- Underdrains for media filtration
- Seawater desalination
- Water treatment and municipal wastewater management: Used in filtration beds and underdrain plates to treat potable water by removing suspended solids and impurities.
