Ozone Contact Skids

Pureflow Biofloc decided to design ozone contact chambers skid and ozone generators contact towers from scratch. Our equipment derived after spending over 3 years in R&D and field trials of ozone contact chambers. Traditionally it was considered that providing a standard pressurized chamber for the ozone to be infused in water was enough. Pureflow Biofloc has the field expertise from operating large ozone generators in saline and fresh water farm systems and understands that there are multiple details that need to be addressed in order to secure the brood-stock of the fish farm. Details in the design and safe operation of the device are unique on Pureflow Biofloc ozone contact chambers.

In saltwater Recirculating Aquaculture Systems (RAS), using a venturi device with a protein skimmer not only remains traditional but also proves highly effective. Moreover, since the venturi creates a vacuum that draws ozone gas into the water, the skimmer’s foam fractionation process—naturally more efficient in saltwater due to dissolved organic compounds—enhances gas-liquid transfer and removes waste effectively.

However, freshwater RAS facilities operate under different dynamics. Because protein fractionation is far less effective in freshwater, protein skimmers are rarely applied. Consequently, advanced infusion methods become necessary. Modern systems, therefore, incorporate a pressurized ozone contact vessel or an ozone contact tower.

In addition, this specialized vessel creates the right conditions for ozone infusion. Instead of relying only on a venturi, the system forces a pressurized mixture of ozone and water to mix thoroughly within the chamber. As a result, the gas-liquid contact time significantly increases, and disinfection efficiency improves.

Furthermore, this method ensures ozone not only disinfects the water but also breaks down organic waste more effectively. Ultimately, for most modern freshwater RAS farms, an ozone contact tower becomes a critical component to achieve and maintain superior water quality standards, support biosecurity, and enhance system sustainability.

We design each Ozone Contact Skid with precision engineering, ensuring optimal ozone transfer efficiency and safety.Furthermore, our systems are customizable to match your flow rates, contact times, and site-specific needs.As a result, you get a turnkey ozone treatment solution that delivers reliable performance and long-lasting value.
