What is a Wedge Wire Nozzle

JX Filtration June 30, 2025 Wedge Wire Nozzle

A Wedge Wire Nozzle is a type of water distribution and collection device, primarily used to evenly distribute influent and collect effluent. It ensures uniform flow through the ion exchange resin bed, helping to prevent channeling and resin loss.

Classification by Structure:

Wedge wire nozzles can be categorized into several types based on their structural design:

Slotted Nozzle
Perforated Nozzle
Umbrella Nozzle
Star Nozzle
Adjustable Nozzle

Features of the Slotted Nozzle:

Advantages:

Effectively prevents the loss of fine resin particles.
Suitable for ultrapure water systems.
Ensures uniform water flow distribution, minimizing dead zones.
Enhances ion exchange efficiency.
Accommodates high flow rates while still controlling resin loss.
Compact design, ideal for small-scale systems.

Disadvantages:

Prone to clogging, especially in applications involving suspended solids.
Requires high manufacturing precision.
Not cost-effective for large-scale or low-budget projects.
Relatively weak backwashing capability—some particulate matter may be difficult to discharge.
