OZONE FOR BOTTLED WATER
For over 50 years, ozone has played a key role in the bottled water industry as a widely adopted oxidation and water treatment technology. Ozonation has historically been implemented to support water quality management and process control within bottled water production facilities.
In the early development of the bottled water industry, maintaining consistent water quality during storage and bottling presented operational challenges. The introduction of ozone-based treatment systems helped address these challenges, establishing ozonation as a standard processing step in modern bottling operations.
Final performance and equipment selection depend on the wastewater matrix, ozone demand, transferred dose, contact conditions, monitoring requirements and required treatment result.application and process information you already have. We will help determine what comes next.
Use Ozone as One Controlled Stage in the Bottled-Water Process
Ozone is commonly evaluated as part of an integrated water-treatment and bottling process rather than as a replacement for every treatment stage.
The exact role depends on what the plant needs to accomplish, what treatment occurs before ozone, where ozone will be injected and contacted, and what must be verified before the finished product is filled and released.
ENGINEERING PRINCIPLE
Start with the treatment objective and source-water conditions—not the generator model.
A suitable ozone generator is only one part of the process. Oxygen supply, gas-flow control, injection, contact, monitoring, off-gas management and site integration may also affect the final configuration.
Oxidation and Water-Quality Management
Evaluate ozone after upstream treatment when a specific oxidizable load, color, odor or residual contaminant remains.
Integrated With Existing Treatment
Ozone may follow filtration, reverse osmosis, UV or another treatment stage depending on the facility’s process, objective and regulatory basis.
Generated Where It Is Used
Ozone is produced on-site from a suitable feed gas and introduced into the process through controlled gas flow, injection and contact equipment.
Chemistry, Contact and Validation Matter
Water chemistry, ozone demand, transferred ozone, contact conditions, process-control targets and the verification method affect the equipment direction.
What Wastewater Problem Are You Trying to Solve?
The required equipment direction changes with the treatment objective. Ozone may react quickly with one wastewater constituent while a different constituent creates a much larger ozone demand.

Protect Product Quality While Controlling the Ozone Stage
Bottled-water applications require the treatment objective to be balanced against source-water chemistry, product quality, contact conditions, process monitoring, worker safety and applicable regulations.
01
Review Source-Water Chemistry Before Ozonation
Where source water contains bromide, ozonation can form bromate. Bromide, pH, alkalinity, dissolved organic matter, ozone exposure and other process conditions may affect formation and control.
02
Identify What Will Consume Ozone
Organic matter, reduced minerals and other constituents may consume ozone before the desired process condition is achieved. Source-water data and testing may be needed where demand is uncertain.
03
Distinguish Generated Output From Process Residual
Generator output, applied dose, transferred ozone and measured residual are related but are not the same value. The process-control target must be defined for the actual system.
04
Protect Taste, Odour and Product Characteristics
Operating conditions should be validated so the intended treatment objective is achieved without unacceptable effects on finished-water quality or the product’s expected characteristics.
05
Confirm Monitoring, Exposure and Jurisdictional Requirements
Gas monitoring, ventilation, off-gas handling, worker exposure, finished-product requirements and the permitted use of ozone depend on the installation and jurisdiction.
