Aquaculture is the most rapidly growing sector of food production worldwide.According to the FAO (Food and Agriculture Organization of the United Nations), current global food production needs to increase 70% by 2050 in order to feed 2 billion additional people. The growth of aquaculture will become an increasingly important part of that future food supply, while paying particular attention to environmental concerns.Higher fish density can lead to pathogen increase which is a significant threat to aquaculture operations.   According to a 2012 ‘World Review of Fisheries and Aquaculture’ report, ‘disease outbreaks in recent years…have affected… marine shrimp farming in several countries in Asia, South America and Africa, resulting in partial or sometimes total loss of production.’


Ozone is a very powerful bactericide and viricide and, unlike other agents, it leaves no undesirable residues.  An ideal method of disinfecting water is by ozonation in a contact tank prior to use.

In general, the main reasons for using ozone in water treatment are: Partial or total oxidation of dissolved matter Precipitation of dissolved matter Micro-flocculation of organic matter Destabilisation of colloidal matter Disinfection

Unlike such agents as chlorine, or any of its derivatives, oxidation with ozone leaves no hard to handle or toxic residues requiring subsequent complex treatment. In practice, ozone immediately starts to attack the oxidizable components it comes into contact with. This property makes it a very powerful disinfectant. Because the process only leaves “oxygenated” products and oxygen, it is particularly well suited for applications such as hatchery water where the presence of undesirable elements after treatment could have grave consequences.

TES Ozonators have been successfully deployed and currently being used  in several private high-tech hatcheries up down the coast line from Kakinada to Chennai to Marakkanam.

Using Ozone has been proven to:

  • Significantly increase yield per cycle
  • Drastically reduces the aeration time required when compared to Chlorine disinfected water.
  • Increase the number of cycles or batches  per year
  • Result in Increased overall hatchery productivity.

Grow out

Ozone is increasingly used in aquaculture due to its numerous advantages over traditional water treatment methods. The use of ozone is the most effective method for providing high-quality water for fish farming.

Disinfection by ozone can reduce the risk of disease in aquaculture systems and results in less need for vaccination, less use of anti-biotics and leads to higher growth rates and decreased mortality.

As the strongest, technically producible oxidising agent it fulfills further functions apart from disinfection. During the ozonation process ozone is consumed completely and breaks down again into oxygen.

Ozone Advantages

  • Increase D.O. (Dissolved Oxygen)
  • Reduction of Diseases, reduce stress on the fish and Prawn
  • Reduce Ammonia and Nitrite
  • Faster Growth Rate  and Lower FCR
  • Better quality of Prawn and Fish
  • Higher Standard of Environmental Control and Much better pond bottom

Dissolved oxygen content of the water of fish ponds is one of the most important parameters of water quality, as the oxygen is a vital condition for all the organisms living in the water.   The DO content of the fish pond varies over a period of 24 hours. The photosynthesis starts gradually from the early morning hours while the DO content of the water is increasing. The maximum value can be observed early in the afternoon.

From the late afternoon hours photosynthesis is rapidly decreasing and is stopped after dark. The DO content of the water is also decreasing during this period. Also at night time the algae go through the respiration cycle (opposite effect of photosynthesis), giving out CO2 and consuming the DO.

This means that during night times the DO levels keep falling and are lowest in the early morning hours. This puts severe stress on the Prawn/Fish. Especially during molting periods. It is extremely important to maintain sufficient DO levels at all times.

This is accomplished by keeping the TES Ozonator running through the night. Maybe turned off during afternoon hours, between 10 AM and 3 PM. This helps to keep the DO levels at a steady level and not allow to go up and down causing stress.

Prawns are naturally stressed during molting, but if the DO levels are lower than 4 ppm (mg/l), it increases the stress. The opposite is also true, where by having sufficient DO levels, the prawns and Fish are less stressed, feed better, and grow faster.>

Ozone is used in fresh and saltwater (marine) aquaculture to improve the water quality by reduced organic loading, bacteria, viruses, fungi, etc.

Post-Harvest Processing

Ozone is a very powerful oxidizer with several times the oxidizing potential of chlorine bleach and several thousand faster action, so very short contact time is required.  . A natural disinfectant, ozone is replacing traditional chemical oxidants in a growing number of industrial processes, including food, beverage, dairy and seafood processing.

Ozone destroys all common pathogenic organisms through natural processes of oxidation, disinfection, and decomposition to oxygen (O2). Because ozone is powerful in cold water, it reduces the need for hot water and steam, saving water, energy, time, and money.

Seafood Processing Applications.Ozone can be used in a wide range of applications:

  • Surface sanitization
  • Disinfect equipment,tools,storage area, bins,and  refrigeration units
  • Odour control
  • Preserve seafood products/extend shelf life and keeping quality
  • Disinfect process water
  • Ozone ice for fish storage
  • Clean-in-place (CIP) processing lines and heavy equipment.
  • Blast freezing shrimp with ozonated water for export

TES Ozonators

We are the only manufacturer in India, using in-house developed Glazed CERAMIC coating technology for the electrodes. The electrode is the heart of an Ozonator.

Typically other ozonators use GLASS electrodes, which tend to have a very short life of a few months, before they crack or puncture, in the ozone formation process.  Most other sources of Ozonators are resellers of the product imported from china, etc., and do not have any control on the quality of the product.

We manufacture all our products from scratch, at our factory in Chennai, TN, where we have an in-house Research and Development team.  This allows complete control over the quality of the product

Some of our customers include:

  • BMR Hatcheries (Using TES Ozonators in all of their hatcheries at multiple locations along the east coast, Chennai, Marakkanam, etc.,
  • Golden Marine Hatcheries, Marakkanam near Pondicherry
  • DSF  Hatcheries, Kakinada
  • Sapthagiri Hatcheries, Kakinada
  • Bayfry/Saranya Hatcheries, Kakinada
  • Samudra Hatcheries, Kakinada
