Application Of Ozone & AOP in Aquaculture & Hatcheries - by chemtronics

  1. 1. 1 Water Management In Single Pass
  2. 2. - Index 2 • Importance Of Raw Water In Aquaculture / Hatchery • Present Water Treatment Process/Trend • Chlorine Issues & Limitations • Alternate Option; Why Ozone • Ozone Solution • Advance Oxidation Process • Process Flow Diagram • Ozone Sizing Calculation • References
  3. 3. - Role of Water Treatment in Aquaculture / Hatcheries 3 • Aquaculture Industry - Seed | Water | Infrastructure | Feed | Science | Technology • Quality of Raw Water | Water Treatment | Water Quality Maintenance
  4. 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. 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. 6. - What Is Alternate Solution 6 OZONE & AOP Advance Oxidation Process
  7. 7. - Why Ozone & AOP 7
  8. 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. 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.

  11. 11. - Process Flow Diagram – With Advance Oxidation Process 11
  12. 12. - Picture – Integrated Ozone System [IOS] 12 IOS Site
  13. 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
