JX Filtration September 30, 2025 Wedge Wire Nozzle

A stainless steel wedge wire nozzle is a key component in the underdrain system of filter tanks, designed for water and air backwashing. It effectively removes sludge and debris from the filter bed, ensuring stable water quality and flow during operation.

The nozzle has a robust and reasonable structure, with secure connections, high pressure resistance, and a slot design that maintains shape under load. This prevents dead zones between filter plates, avoids sludge accumulation, and delivers excellent performance.

Key Features of Wedge Wire Nozzles:

Clog-resistant design
High filtration efficiency
Corrosion- and rust-resistant
High-temperature resistant
Cost-effective and environmentally friendly
Easy to install and replace

Common Types of Stainless Steel Wedge Wire Nozzles:

Double-head stainless steel nozzle
Single/double flow rate nozzle
Single-head wedge wire nozzle
Long-handle wedge wire nozzle

Applications of Wedge Wire Nozzles:

Wedge wire nozzles are widely used in water and air backwashing systems of filter tanks. They are suitable for single water backwashing, gravity filters, pressure filters, ion-exchange filter beds, and other water treatment equipment.
Applications include municipal drinking water, industrial water purification, high-purity water systems, and the removal of COD, color, odors, and toxic substances from water.
