4. - Present Water Treatment / 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

6. - What Is Alternate Solution
6
OZONE & AOP
Advance Oxidation Process

7. - Why Ozone & AOP

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.

13. - How to Size Ozone Generator
13
Ozone Generator Capacity = Water Flow Rate X Ozone Dose
(gm/hr) (m³/hr) (gm/m³)
Water Flow Rate : Sea Water Intake Flow Rate
Ozone Dose : 2.0 – 4.0 gm/m³ [ppm] ; O3 Dose Depends
On Raw Water Characteristic Ozone Integration Technology
Sea Water Contamination Total Inorganic Load Feed Oxygen Quality Required Residual Dissolved Ozone
Micro-organism Load Oil & Grease Ozone Concentration Ozone Dissolution Efficiency in %
Total Organic Load Chemical Traces Feed Ozone Pressure Contact Time
