Water Treatment Filter nozzles play a critical role in the performance, efficiency and reliability of modern water and wastewater treatment systems. As the primary interface between the filtration media and under-drain system, they ensure even flow distribution, prevent media loss and maintain the long-term integrity of filtration beds. Tecpro Australia supplies a comprehensive range of premium filter nozzles designed for municipal, industrial, desalination and commercial water treatment plants.

Precision Engineered for Reliable Filtration

Filter nozzles must withstand constant hydraulic pressure, backwashing cycles and corrosive environments. Tecpro’s nozzles—manufactured by ILMAP, one of the world’s leading specialists—are engineered to deliver dependable performance over many years of continuous operation.

Key features include:

• Uniform flow distribution for consistent filtration results

• Accurate slot and gap sizes to prevent media loss

• High mechanical strength to withstand repeated backwash cycles

• Chemical-resistant materials for harsh or chlorinated environments

• Low-pressure losses for energy-efficient operation

Available in polypropylene, ABS, PVC, and stainless steel, our nozzles suit a wide range of process conditions.

Applications Across the Water Industry

Tecpro filter nozzles are designed for use in:

• Municipal water treatment plants

• Wastewater treatment and tertiary filtration

• Industrial process water systems

• Sea water desalination (SWRO)

• Deionisation and softening units

• Sand and multimedia filters

• Gravity or pressure filters

• Activated carbon filters

Whether replacing individual nozzles or specifying for a new plant, we provide solutions tailored to media type, tank size, flow rates and operating pressures.

Types of Filter Nozzles We Supply

We offer a wide selection of configurations to suit different under-drain and tank designs:

Standard Threaded Nozzles

Ideal for most gravity and pressure filters; available in multiple stem lengths and slot sizes.

Lateral & Header Nozzles

Designed for large industrial filters or high-flow applications requiring balanced distribution.

Stainless Steel Nozzles

Maximum durability for corrosive environments, high temperatures or aggressive backwash cycles.

Nozzles with Collector Arms

Provide increased surface area for large tanks or uneven tank geometries.

Bridge Slot, Wedge Wire or Laser-Cut Solutions

For precise gap control and superior media retention.

All nozzles can be matched with a full range of accessories including screens, gaskets, nuts, plates and custom stem lengths.

Enhancing Filtration Efficiency

Using the correct filter nozzles is essential for:

• Preventing sand/media loss into the outlet system

• Achieving uniform backwash expansion

• Eliminating dead zones and channeling

• Reducing maintenance and unplanned downtime

• Extending the life of filter media

• Optimising plant performance and water quality

Tecpro’s engineering team can help select the right nozzle based on filter design, media size, flow conditions and water chemistry.
