Ozone Contact Chambers
Ozone contact chambers bring ozone gas and water together in a defined treatment loop. Pureflow Bio manufactures contact-chamber and skid arrangements in India for engineered aquatic treatment projects.
What are Ozone Contact Chambers?
An ozone contact chamber provides a defined gas-and-water mixing stage within an ozone treatment system, with transfer and contact conditions established for the application.
Ozone Contact Chambers applications
RAS facilities
Best for a dedicated ozone treatment branch with controlled return water.
Public aquariums and oceanariums
Best for an engineered contact stage with livestock protection measures.
Aquaculture water treatment
Best for a defined oxidation objective and commissioning protocol.
How Ozone Contact Chambers work
Introduce the treatment stream
Feed water and ozone through the approved injection arrangement.
Provide contact conditions
Operate the selected vessel and mixing route at the design flow and pressure.
Separate and verify
Manage off-gas and confirm the permitted return-water residuals before the stream rejoins the system.
Ozone Contact Chambers features and benefits
Defined contact vessel
Creates a planned location for the gas-water treatment stage.
Integrated pipework
Coordinates injection, circulation and isolation in the agreed arrangement.
Accessible instrumentation
Allows the specified pressure and residual measurements to be incorporated.
Separable off-gas route
Provides a connection for the designed gas-handling equipment.

The OCSU schedule specifies ozone dosing, tank diameter, connections and a 2–7 bar working-pressure listing. Tank-height and power units are not printed. Model names OCSU 20-35 and OCSU 110-125 differ from their dosing rows of 20–30 and 100–125 g/h; confirm the selected model, pressure documentation, power units and electrical supply in the quotation. These listings do not establish a water flow or contact-time guarantee.
Configuration and supply details
Confirm materials, connection standard, dimensions, electrical requirements and included components for the selected equipment. The quotation defines the approved scope.
Optional components
- Injection, pumps and controls as expressly listed in the quotation
Options are supplied only when included in the agreed quotation.
Engineering & procurement
Contact time, residual control and material compatibility
A contact chamber must work within a complete ozone process. Vessel dimensions and a generator connection do not establish a verified contact time or suitable return-water condition.
Use effective contact volume
Nominal hydraulic time = working contact volume ÷ water flow, using consistent units. Short-circuiting, gas hold-up and mixing can make actual exposure differ from nominal residence time. Confirm the selected operating level and hydraulic arrangement.
Treat marine oxidant residuals as a design issue
Marine and brackish water chemistry can generate secondary oxidants. Define monitoring, residual-removal arrangements and acceptance limits for the actual water and species. Do not rely on an assumed universal ORP setting.
| Selection item | Specify or verify | Why it changes the selection |
|---|---|---|
| Contact arrangement | Working volume, flow distribution, mixing and nominal contact time | Outside vessel dimensions do not establish the effective treatment volume. |
| Dosing and transfer | Ozone mass, injected gas flow and transfer basis | Generator output and dissolved dose are not interchangeable. |
| Pressure and materials | Approved pressure, pressure protection, seals and gas/water compatibility | The project drawing and component ratings govern installation. |
| Residual and off-gas handling | Water residual control, gas destruct, ventilation and interlocks | Water and gas streams need their own defined treatment routes. |
How to select Ozone Contact Chambers
A chamber volume does not establish treatment performance unless the actual flow, mixing and ozone chemistry have been reviewed.
- Water flow and ozone demand
- Effective contact volume
- Operating pressure and gas transfer
- Residual monitoring and off-gas flow
- Materials, return-water limits and ventilation

Ozone Contact Chambers FAQs
What is an ozone contact chamber for?
It gives ozone time to dissolve and react with the water away from your fish. Ozone gas is mixed into a side stream, given enough contact time to oxidise organics and kill microbes, and the water is then sent on for residual removal before it returns to the system.
Why not just add ozone straight into the tank?
Ozone is toxic to fish at very low levels and burns gills. A contact chamber keeps the reaction in a closed vessel and lets you control the dose, so the fish only ever see clean, ozone-free water.
How is the contact chamber sized?
By the flow you want to treat, how much ozone you're adding and the contact time needed. Our OCSU models are specified by ozone dose, tank diameter, connections and a 2 to 7 bar working pressure. We help pick the model once we know your feed rate and treatment goal.
What happens to the ozone that doesn't dissolve?
It leaves the chamber as off-gas and must go through an ozone destruct unit before it's vented. Residual ozone still in the water is removed by contact time, carbon, a trickle filter or UV before the water returns to the fish.
What materials can handle ozone?
Ozone attacks many plastics and rubbers. Contact chambers and the fittings around them need ozone-resistant materials and seals, which is why it pays to buy the chamber and its fittings as a matched set rather than improvising with standard pipe fittings.
