  - Present WaterTreatment / Trends In Hatcheries 4 1. Sea Water Intake 2. Sea Water Slow Gravity Sand Filtration / Rapid Pressure Sand Filter 3. Disinfection of Sea Water Using Chlorine in Chlorination Tanks 4. Transfer to Holding Tanks for 5 – 15 Days For Chlorine Disintegration 5. Addition of More Chemicals to Neutralise Residual Chlorine like SMBS 6. UV Disinfection 7. Transfer To Aquaculture Tanks
• 5.
  - Chlorine Issues& Limitations 5 • Chlorine Dose is Difficult to Control • Danger Associated With Chlorine • Poor Water Quality Due To Chlorine Disinfectant By-products • Chlorine Disinfection is Comparatively Slow • Chlorine Disintegration Is Time Consuming • Chemical Storage | Transportation | Handling • Residual Remains in water, Creating Stress on Aquaculture

  - Why Ozone& AOP 7
• 8.
  - Ozone Solution 8 •Ozone Is 3,000 times faster than Chlorine • Ozone Reaction By-products are harmless • Ozone Residual, disintegrates to harmless Oxygen • Increases Dissolved Oxygen level on Disintegration • Short Process Time 2 hrs – 20 hrs • AOP - Ozone With U.V. • Ozone Disinfected Water Is Light & Healthy for Aquaculture
• 9.
  - AOP –Advance Oxidation Process 9 • Latest Technique, But Time Tested • Ozone in Combination with High Dose of Ultraviolet Radiation • Ozone In Presence Of High UV Produces “Hydroxyl Radicals [OH]” • OH ¯ Has Very High Oxidation Potential [Ozone : 2.07 ; OH¯ : 2.80] • Reaction Time is In Micro Seconds • AOP Completely Consumes Residual Ozone – Higher Safety For Aquaculture • No Extra Consumables.
