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

- 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

OZONE & AOP

Advance Oxidation Process

- Why Ozone & AOP

7

WORKS VERY FAST

NO DISINFECTANT BY-PRODUCT

INCREASES CULTURE HEALTH, SAFETY & GROWTH

REDUCES MORTALITY

USDA | FDA | GRAS - CONFIRMATION

ENVIRONMENTAL FRIENDLY

- 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

- 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.
