Industrial water users face a unique combination of challenges: high-volume process water requirements, strict effluent discharge standards, and often complex source water quality issues that affect process performance and equipment longevity.

UV disinfection and UV-based photolysis are applied across industrial and manufacturing settings for pathogen control, dechlorination, ozone destruction, TOC reduction and advanced oxidation. It is a compact, reliable technology that fits into complex process water systems without the complications of chemical dosing.

Core Applications in Industrial Settings

UV treatment is used across several distinct process water functions in manufacturing:

  • Cooling tower water: treating make-up and recirculating water to control Legionella and biofilm formation.
  • Ultrapure water production: removing chlorine and chloramines before ion exchange and membrane stages.
  • Effluent polishing: disinfecting treated wastewater before environmental discharge to meet licence conditions.
  • Process water disinfection: protecting water-cooled tooling, hydraulic systems and product contact circuits.
  • Ozone destruction: removing residual ozone from water treatment systems before discharge or reuse.

Industrial and Manufacturing Application

UV in Ultrapure Water Systems

Semiconductor fabs, electronics manufacturing and high-precision optical production require ultrapure water with extremely low levels of total organic carbon, ions, particles and microbial contamination. UV is a standard component of ultrapure water production systems for two reasons: dechlorination ahead of ion exchange systems, and TOC reduction through UV photolysis at 185nm.

At 185nm, UV light generates hydroxyl radicals from water molecules, which attack and mineralise organic compounds. Combined with longer wavelength 254nm UV, this achieves both disinfection and TOC reduction in a single inline unit.

Chlorine and Chloramine Destruction

Legionella Control in Industrial Cooling Systems

Cooling towers and evaporative condensers in industrial facilities are primary Legionella risk environments. Warm water, recirculation and aerosol generation create conditions where Legionella pneumophila can proliferate rapidly if water quality management is inadequate.

UV disinfection of cooling tower make-up water and recirculating water provides continuous microbial control without the corrosion and environmental concerns associated with high chemical biocide dosing. It is used in conjunction with chemical treatment rather than as a complete replacement.

Warm Water and Legionella Control

Effluent Treatment and Discharge Compliance

Industrial wastewater treatment processes produce effluent that must meet licence discharge standards for microbial quality before release to sewer, waterway or land. UV disinfection of treated industrial effluent is a well-established approach that avoids the residual chlorine issues that arise with chemical disinfection.

UV Guard commercial systems can be sized for industrial effluent treatment applications including food processing wastewater, abattoir effluent and general manufacturing trade waste.

Frequently Asked Questions

Yes. UV Guard commercial systems are available in large flow rate configurations and can be installed in parallel arrays for very high flow applications. Contact the team with your peak flow requirement and water quality data for a system recommendation.

UV photolysis at 254nm does not significantly alter water chemistry beyond the targeted reactions. pH, conductivity and total dissolved solids are not affected. This is important in process water systems where chemical balance is critical.

This depends on the source water quality and the UV application. For cooling tower make-up water from mains supply, minimal pre-treatment is typically needed. For process water from bore or recycled sources, sediment filtration and potentially iron or turbidity management is required before the UV stage.

Yes. UV disinfection is recognised by Australian environmental authorities as an acceptable disinfection technology for wastewater effluent discharge and reuse applications. UV Guard can provide system performance documentation for regulatory submissions.

UV Guard commercial systems include UV intensity monitoring with alarm outputs that can be integrated into plant control systems. Remote monitoring options including data logging and alarm notification are available on commercial units.
