Ozone Systems
Ozone is a powerful oxidant generated on site and introduced into the treatment process. It can oxidize dissolved organics, reduce color-causing compounds, and support disinfection. In many marine exhibit systems, ozone is an important tool for achieving and maintaining high water clarity.
An ozone system for aquatic use includes ozone generation, oxygen or air feed, injection, a contact chamber, residual (ORP) control and off-gas destruct; an ozone generator alone is not an ozone system.
Because ozone presents material safety and compatibility considerations, it should be specified and coordinated as a complete treatment system rather than as a standalone generator.
What an ozone system includes
A generator, a feed gas supply, an injection and contact arrangement, a means of removing residual ozone before water returns to animals, and off-gas destruct. Ozone is a system, not a component. Pricing the generator alone is a scope gap, and a common one.
The contact chamber is where the ozone actually works: a vessel or pipe reactor sized for the contact time the design requires, followed by residual control on ORP and an off-gas destruct unit so that no ozone reaches the animals, the guests or the equipment room.
Where it’s used
Marine aquarium and zoo exhibits. Aquaculture where organic loading is heavy. Water features requiring high clarity. Applications where color and dissolved organics defeat mechanical filtration.
Why specification matters
Residual ozone can harm aquatic life. Water leaving the ozone contact process therefore requires appropriate residual-control measures before it returns to the habitat. Depending on the design, that can include adequate contact time, degassing, activated carbon, UV, or other methods approved for the application.
Off-gas control is a critical safety consideration. Ozone accumulation in an equipment room can expose staff, so off-gas destruct, ventilation, area monitoring, and other required safeguards should be addressed in the base system design and equipment scope.
Feed gas determines generator capacity. A generator produces substantially more ozone from concentrated oxygen than from dried air. Oxygen concentrators or liquid oxygen add equipment, space, and operating cost. A generator specified without stating the feed gas is ambiguous, and the ambiguity is worth real money.
Materials must be ozone compatible throughout. Ozone attacks common elastomers and some plastics. Every gasket, seal, valve elastomer, and section of pipe in ozone contact needs verifying. Standard EPDM in an ozone line is a failure waiting to happen, and it is the kind of detail that gets missed when equipment is bought piecemeal.
ORP control is how the system actually runs. Oxidation-reduction potential is the practical control variable. That means ORP probes, controllers, and a control strategy, which puts ozone squarely in the instrumentation and controls scope, not just the mechanical scope.
How SIVAT helps
We review ozone requirements as a complete package: generation, feed gas, injection, contact, residual control, destruct, monitoring, and materials. We check that ozone-compatible materials are specified through the whole contact loop, and we price the system as a coordinated set rather than a generator with parts to be sorted out later.
Ozone is the category where an incomplete equipment package causes the most trouble downstream.
Common questions
What does ozone do that filtration cannot?
Ozone oxidizes dissolved organic compounds. Mechanical filtration removes particles it can physically capture, but the molecules that make water look yellow or hazy stay in solution. On marine exhibit systems, ozone is frequently the difference between acceptable and exceptional clarity.
Is an ozone generator a complete ozone system?
No. A working installation is generation, feed gas supply, injection, contact time, residual destruction and monitoring. Ozone reaching animals is dangerous and ozone accumulating in an equipment room is a staff hazard, so the destruct and monitoring elements are not optional extras.
What drives the operating cost of an ozone system?
Feed gas. A generator produces substantially more ozone from concentrated oxygen than from dried air, so the choice between an oxygen concentrator, liquid oxygen and air preparation sets both the equipment footprint and the recurring cost.
