Process water

Cooling towers.

Cooling circuits face linked issues of biofilm, scale, corrosion and makeup water. Ozone can form part of a recirculating-water control strategy.

Process water

Recirculation changes treatment demand

Review volume, recirculation, blowdown, conductivity, temperature, materials and existing chemical treatment. Inject into a suitable sidestream with mixing and contact; automation and monitoring must match actual tower operation.

Application point

Integrate without losing circuit control

Tower volume alone is insufficient: blowdown, makeup and temperature change the conditions. Ozone is assessed alongside the existing scale and corrosion program.

Injection point, mixing and contact volume are designed for actual flow. Undissolved gas and any residual are managed before water returns to the process.

On-site verification

Track biofilm, water and operation

Track microbiology, water chemistry, circuit condition and chemical use under the operating program.

Sampling points and comparison conditions are defined before claiming a reduction or saving. This helps separate treatment effects from normal process variation.

RO and ultrapure-water tanks

Stored reverse-osmosis, distilled or polished water may need microbiological control without compromising downstream use. Ozone can be applied in recirculation or before the use point.

Assess tank volume, turnover, material, required purity and downstream process sensitivity. Monitor transfer and residual; where the end use cannot accept oxidant, include a removal step before use.

How to verify: Check microbiology, dissolved ozone and process-specific criteria at defined sampling points.

Fire-water storage tanks

Fire-water reserves can remain stored for long periods. Ozone recirculation can be assessed to limit deterioration without interfering with the emergency function.

The priority is preserving fire-system availability, pressure and reliability. Any treatment is designed as an auxiliary loop with material compatibility, isolation, interlocks and coordination with fire-safety personnel.

How to verify: Verify stored-water quality and continued compliance with the fire system availability tests.

Surface washing

Ozonated water can be assessed for washing compatible floors, equipment or surfaces within a documented cleaning program.

Physical soil removal is separate from the hygiene stage. Review materials, contact time, application method, ventilation and worker safety; validate the protocol on the actual surface.

How to verify: Check visible cleaning and surface samples under the facility hygiene plan.
