Advanced Ozone + UV Treatment System
Introduction
Shrimp hatcheries depend on ultra-clean, pathogen-free water and hygienic environments to ensure strong PL production, high survival rates, and consistent quality. Lotus Ozone's advanced Ozone + UV integrated system delivers the strongest form of chemical-free disinfection, protecting all stages from broodstock to PL rearing.
Why Water Quality Matters in Shrimp Hatcheries
Larvae are extremely sensitive to pathogens, ammonia, nitrite and organic loads
Traditional chemicals like chlorine leave residues, require long aging, and create inconsistent results
A combined Ozone + UV system ensures the cleanest possible water with zero chemical residues
Leads to lower mortality, stronger PL, higher hatchery productivity
Ozone Treatment – Key Benefits
Ozone is one of the strongest oxidising agents available
Powerful Pathogen Destruction
- Eliminates bacteria, viruses, fungi and protozoa
- Permanently inactivates viruses
- Breaks down completely into oxygen
Organic Load Reduction
- Oxidizes dissolved organic matter
- Micro-flocculates and precipitates colloids
- Reduces colour, turbidity, COD & BOD
Superior to Chlorine
- 50% stronger oxidising potential
- 3,100 times faster
- Ozone half-life <20 minutes (vs chlorine's 24–36 hours)
- Ultra intensive UV systems make de-ozonation much quicker
Proven Hatchery Results
- Increases yield per batch
- Reduces cycle time by ~4 days
- Increases overall productivity
Introducing UV — The Perfect Complement to Ozone
While Ozone handles deep oxidation, organic removal and bulk pathogen elimination, UV provides instantaneous microbial kill and acts as a final polishing step.
Benefits of UV in Shrimp Hatcheries
Instant destruction of bacteria, viruses, fungi
Does not alter pH, salinity, alkalinity or minerals
Highly effective on low-turbidity water (post-ozonation)
Breaks down any ozone residuals safely
Ideal for recirculation loops or final water polishing
Where UV is Used
Before PL tanks
Before broodstock maturation tanks
On recirculation lines for continuous disinfection
To ensure zero ozone residual in sensitive larval stages
Ozone + UV – The Multi-Barrier System
- Organic load, COD/BOD
- Viruses & bacteria
- Ammonia & nitrite
- Odour & colour
- Micro-flocculation
- Environmental oxidation
- Final microbial kill
- Breakdown of ozone residual
- Prevents recontamination
- Continuous polishing
- Lower ozone dose required
- Higher UV efficiency due to clearer water
- Maximum bio-security for sensitive PL
- Zero chemicals, zero residue
Effluent Treatment System (ETS)
Hatchery discharge water must meet State Pollution Control Board and Coastal Aquaculture Authority standards. Ozone is effective in treating:
High COD/BOD loads
Organic matter
Pathogen-rich discharge
ETS Ozone Benefits
Increases DO
Reduces ammonia & nitrite
Eliminates need for chlorine + dechlorination
Reduces effluent tank size & holding time
Ensures disease-free discharge water
Air Disinfection Using Ozone
Airborne microbes spread quickly across nauplii, maturation, and PL areas. Lotus Ozone Air Disinfection Systems:
Kill airborne bacteria, viruses, moulds & fungi
Prevent cross-infection
Are portable between sheds
Use timer-based controls for safe continuous operation
Maintain safe working ozone levels: 80–100 ppb
High-level fumigation between batches disinfects every corner and eliminates contamination risks
