RAS Ozone Generator, 5-100g/h Pathogen Control for Hatchery
Advanced Water Disinfection & Clarity Solution for RAS The YUTANK Ozone Generator is a critical water treatment component designed for high-density Recirculating Aquaculture Systems (RAS). By generating strong oxidizing ozone (O₃), it rapidly eliminates pathogens (bacteria, viruses, fungi) and degrades dissolved organic compounds that cause water turbidity and off-flavors. When integrated with YUTANK Protein Skimmers, it significantly enhances filtration efficiency by flocculating fine particles. Ideal for hatcheries and commercial grow-out farms requiring strict biosecurity and crystal-clear water conditions.
Rapid Disinfection: Instantly neutralizes harmful microorganisms like Vibrio and Aeromonas without chemical residue.
Water Polishing: Oxidizes yellow pigments and organic phenols, resulting in superior water clarity.
Yield Improvement: Reduces nitrite load and increases Dissolved Oxygen (DO) as ozone reverts to oxygen.

Product Positioning & Application The Ozone Generator is positioned as the “Biosecurity Firewall” and “Water Polisher” in a RAS setup. It is essential for commercial hatcheries (shrimp, marine fish) where pathogen control is critical, and for indoor RAS factories where water accumulation of organic color needs removal. It typically works in conjunction with protein skimmers or before the biofilter.
Structure & Working Principle
Generation: Uses high-voltage Corona Discharge technology to convert Oxygen (O₂) into Ozone (O₃).
Reaction: Ozone gas is injected into the water via a Venturi injector or mixed within a Protein Skimmer. It acts as a powerful oxidant, destroying cell walls of bacteria and oxidizing nitrite (NO₂⁻) into nitrate (NO₃⁻).
Decay: Unused ozone naturally reverts to pure oxygen within minutes, increasing the system’s dissolved oxygen levels without leaving toxic residues.
Core Advantages & Differences
Enhanced Skimming: When paired with YUTANK Protein Skimmers, ozone changes the surface charge of particles, improving foam fractionation efficiency by up to 30%.
Flavor Control: Effectively oxidizes Geosmin and MIB, preventing the “muddy” taste often found in RAS-farmed fish.
Smart Control Ready: Can be linked to the YUTANK Intelligent Control Cabinet via ORP sensors to automatically regulate dosage, preventing ozone overdose (maintaining ORP ~300-350mV).
Durability: Built with high-grade dielectric tubes and moisture-resistant components to withstand the humid environment of aquaculture facilities.
Compatibility & Integration
Must-Have Pairing: YUTANK Protein Skimmer (serves as the reaction chamber).
Monitoring: ORP Sensor (controls the generator on/off).
Safety: Activated Carbon Filter or Degassing Tower (installed downstream to remove residual ozone before water returns to fish tanks).
Q: How do I determine the correct ozone size for my farm?
A: A general rule of thumb for RAS is 10-15g of ozone per 1kg of feed per day, or roughly 1-2g per ton of water for disinfection. However, exact sizing depends on your bio-load and temperature. Please contact YUTANK engineers for a calculation based on your specific stocking density.
Q: Is ozone dangerous to my fish?
A: Ozone is safe if controlled correctly. We strongly recommend using an ORP (Oxidation-Reduction Potential) controller to maintain levels between 250-350mV. Additionally, ensuring water passes through a degassing tower or biofilter after ozonation ensures no residual ozone reaches the culture tanks.
Q: Can I use this with a standard air pump?
A: For small units, dry air is acceptable but less efficient. For industrial efficiency, we recommend using a PSA Oxygen Generator as the feed source. Using pure oxygen increases ozone concentration significantly and prevents the formation of nitric acid byproducts found when using humid air.
Q: Does this replace the UV Sterilizer?
A: While both disinfect, they work differently. Ozone physically removes solids and organics (improving clarity) which UV cannot do. UV is a passive sterilizer. Many high-end RAS systems use both: Ozone for water clarity/primary disinfection, and UV as a final safety polish.
