Ozone in shellfish purification plant

Water quality for your shellfish

Use of Ozone in Shellfish Purification Plant


Use of Ozone in Shellfish Purification Plant

In shellfish depuration systems with water recirculation, ozone is used as an advanced oxidizing agent
to improve water quality and process efficiency. Its action effectively removes
dissolved proteins, organic compounds, microorganisms, and biofilms that accumulate during depuration.
It also reduces the formation of surface foams, heavy metals, and viruses. This not only improves
water transparency and oxygenation, but also extends its reuse, minimizes water consumption,
and contributes to maintaining a microbiologically stable environment, without residues or added chemicals. 

Disinfects without residue, improves water quality and provides extra oxygen

Ozone is a powerful disinfectant and water purifier

  Ozone is generated on-site, it does not need to store or transport chemicals

Ozone does not leave residues, it does not accumulate in living beings

The system is automated, you do not need manpower to apply it

Are there problems with water quality in a shellfish purification plant?

Advantages of using ozone in shellfish purification plant

Maximum disinfection without residue

Maximum disinfection without residue

Ozone is used worldwide in the disinfection of water for shellfish purification, thanks to its powerful capacity to eliminate viruses, bacteria, fungi, and molds, with the advantage that it leaves no residues and does not accumulate in living beings. A fundamental tool for improving process efficiency.

Purifies and improves water quality

Purifies and improves water quality

Ozone is an excellent purifier, it oxidizes and reduces organic and inorganic matter, reduces COD, BOD, SS, SD, turbidity, color, odor, and taste. It eliminates toxins and heavy metals. In addition, it provides an extra of dissolved oxygen.

Increase productivity

Increase productivity

It reduces the maintenance of filters, skimmers, and conduits by avoiding biofilm. It prevents bad odors associated with decomposing organic matter. It facilitates compliance with biological parameters, all without the use of chemicals.

Without labor, automatic


The system generates ozone and injects it into the tank automatically, without the need to apply manual labor in the process. The equipment only needs to connect to the Skimmer to be treated and provide it with a light point.

No chemical storage


Ozone cannot be transported or stored, it is generated on site, and it is applied instantly, so it is not necessary to store and manage chemical products, it avoids transport and reduces the carbon footprint.

Biocide recognized by the ECHA


Ozone is on the list of biocides by the European Chemical Agency and ZonoSistem has all the necessary legalization documentation to be able to apply ozone in its process.
