How we specify the right ozone generator

Ozone systems are application-specific, and the correct generator capacity depends on your process conditions and safety requirements. You do not need to choose a generator yourself. If you share the basics below, we will recommend the correct ozone capacity and system architecture.

  • Application and goal Water treatment, air & odour, or process oxidation (and what you need to achieve).
  • Flow or volume Continuous flow (m³/h or L/min) or tank volume (m³), plus batch vs continuous.
  • Target level Residual / ORP target / CT requirement, or simply the problem you want solved.
  • Process conditions Temperature, water quality (organics/turbidity) or air conditions (humidity/volume).
  • Materials and site constraints Wetted materials, space, ventilation, and installation preferences.
  • Safety and control Destruct, ambient monitoring, interlocks, and preferred control (ORP / DO₃ / timer).
Compliance

Our ozone generators are available in a wide range of outputs and configurations for water treatment, oxidation, odour control and process applications. System options vary by duty and may include integrated oxygen supply, PLC/HMI control and application-specific layouts.

Ozone Generators

UK-based engineering. Worldwide projects.

Engineered for Your Duty

We size ozone capacity to your flow, target residual, and contact time, not just a generic g/h label. Temperature, water quality, and mass transfer efficiency are considered from the start.

Control That Matches the Process

Choose the right control strategy for your application, including ORP and/or dissolved ozone (DO₃) feedback. We define setpoints, alarms, and turndown behaviour so performance stays stable in real operation.

Industrial Build, Serviceable Design

Designed for continuous duty with practical access for maintenance and inspection. Component selection and layout are made with uptime, spares, and long-term ownership in mind.

Monitoring & Diagnostics

Instrument options for ozone output, gas flow, pressures, and key interlocks, with clear fault states. This supports faster commissioning, easier troubleshooting, and less downtime over the life of the system.

Complete System Integration

Oxygen supply (PSA or LOX), injection, contact tank, degassing, and off-gas destruction are engineered as one package. The result is predictable performance, not a collection of parts.

Designed for Safe Operation

We build in practical safety measures such as ozone monitoring, ventilation strategy, alarms, and permissives. Documentation and commissioning checks are aligned with typical UK/EU site expectations.

Materials & Compatibility Checks

Ozone is unforgiving on the wrong materials. We consider seals, plastics, piping, and downstream equipment compatibility early, helping avoid premature failures and corrosion issues later.

Commissioning, Training & Support

We provide a clear handover, operator guidance, and support for setpoints and maintenance. The aim is a controlled “yes/no” outcome during commissioning and consistent results afterwards.

What is an
Ozone Generator?

An ozone generator is a specialist system used to produce ozone for controlled industrial and commercial applications, including water treatment, odour control, hygiene support and process oxidation. Technically, it produces ozone (O₃) from oxygen (O₂) using corona discharge or other ozone generation methods. In practical applications, however, the generator is only one part of the system. Performance also depends on correct sizing, ozone concentration, gas transfer, contact time, monitoring, off-gas handling and safe integration with the wider process.

Typical applications include:

  • Water treatment: disinfection, biofilm control, oxidation of organics and colour.
  • Air & odour: unoccupied treatment cycles, odour removal and hygiene support.
  • Process oxidation: contaminant reduction and targeted oxidation in industrial processes.
  • Safe operation: off-gas destruct, ambient monitoring, ventilation and control interlocks where required.

Note: exact ozone generator sizing depends on duty cycle, oxidation demand, contact time, and the selected injection/control method.

Frequently Asked Questions

Ozone generator sizing and system design depend on the application, target performance, and site constraints. If you share a few basics, we can recommend the right ozone generator capacity and the correct injection, contact and safety configuration.

+What size ozone generator do I need?
We size ozone generators from your flow or volume, target outcome (residual/CT/ORP), temperature, and water or air quality. In practice, the same “ozone generator” can be correct or completely wrong depending on dissolution efficiency, contact time, and the oxidation demand of your process.
  • For water: flow (m³/h or L/min), target dissolved ozone (mg/L) or CT, and water quality.
  • For air/odour: space volume, ventilation rate, humidity, and whether ozone is used in occupied or unoccupied areas.
  • For industrial oxidation: contaminant type, desired conversion, and off-gas handling.
+Do I need an oxygen-fed ozone generator, or can I use dry air?
Oxygen-fed systems are usually preferred for stable output, higher ozone concentration, and continuous industrial duty. Dry air-fed ozone generators can suit lower output requirements and simpler applications, but will typically produce lower concentration ozone and may not be ideal for demanding water treatment or high duty cycles.
+Corona discharge vs electrolytic ozone generators: what is the difference?
Corona discharge is the most common technology for industrial ozone generation, especially where higher output is needed. Electrolytic ozone generators produce high-purity ozone directly from water, without a separate oxygen or air feed gas, and are often used where purity is critical or a compact, low off-gas approach is required.
+How is ozone injected into water?
Ozone is typically dissolved using a venturi injector, static mixer, and a sidestream recirculation loop, or via a contact tank system for longer contact time. The best approach depends on your flow, the required CT, and how you manage off-gas safely (destruct and venting).
+Do your systems include ozone analysers and control as standard?
Analysers are not “one-size-fits-all”, so they are typically specified as options. We can integrate gas or dissolved ozone measurement (and/or ORP) with closed-loop PLC control where it adds real value for performance and compliance.
+Is ozone safe, and what safety equipment is required?
Ozone must be treated as a strong oxidant and controlled properly. Safety design typically includes one or more of the following: ozone destruct for off-gas, ambient ozone monitoring, ventilation interlocks, emergency stop, and process interlocks (flow/pressure/door switches) depending on the application and whether areas are occupied.
+What materials are compatible with ozone?
Material selection depends on ozone concentration, temperature, and whether it is gas or dissolved ozone. As a general rule, PTFE/PFA and suitable grades of stainless steel are commonly used, while many elastomers and some plastics can degrade over time. We provide material compatibility guidance during specification.
+Can you supply complete ozone skids, not just the generator?
Yes. We supply engineered packages that can include oxygen generation (PSA or LOX interface), ozone generation, injection/dissolution, contact and off-gas destruct, sensors, and PLC/HMI control. This reduces integration risk and makes performance more predictable on site.
+Do you support projects outside the UK?
Yes. We provide UK-based engineering support with worldwide project delivery. Remote support, commissioning support, and documentation can be tailored depending on site location and local requirements.
+What information do you need to quote or size an ozone system?
The fastest way is to share: application goal, flow or volume, target performance (or the problem statement), temperature, and any key constraints (materials, footprint, power, controls). If some details are unknown, we can still guide you and close the gaps with a short call.
Not sure what you need?
Send us a few details and we’ll recommend the right ozone generator and system layout.
