Chemical-Free Aquaculture Revolution: Advanced Oxidation & Bioaugmentation for Zero-Residue Fish Farming
220,000 tons/year of chemicals - antibiotics, algaecides, and coagulants that accumulate in fish tissue and ecosystems. Juntai's chemical-free aquaculture treatment systems leverage nature-inspired technologies to eliminate toxins while enhancing productivity:
- destroys 99.7% antibiotics without residues
- Strain-specific bioaugmentation
FDA residue-free certification while increasing yields 18% - proving sustainability and profitability coexist.

Table: Performance comparison of chemical vs. AOP treatments in shrimp farms
| 92% (with resistance) | 99.99% (no resistance) | +7.99 pts | |
| 450 ppb | <0.1 ppb | 99.98% ↓ | |
| $1.25/kg shrimp | $0.38/kg shrimp | 70% ↓ | |
| High (BOD +300%) | Negative (BOD -40%) | ||
| +2 tiers |
:
- Electro-catalytic ozonation
- UV-LED photocatalysis: 275nm light activates TiO₂ nanocoated surfaces
- : 50ms bursts prevent biofilm adaptation
2.
Instead of broad-spectrum chemicals, we deploy:
- Vibrio-targeting phagesV. parahaemolyticus within 2 hours
- : JS7 strain suppresses SAP fungi
- Biofilm-disrupting enzymes
: Reduced white spot syndrome by 98% without antibiotics.
3.
- (80-120nm): Remain suspended for 72+ hours, oxidizing deep sludge layers
- : Maintain 200% DO for enhanced nitrification
- : Micro-implosions remove biofouling from tank walls
Integrated Treatment Train for Zero-Chemical RAS
:
- : <0.01 ppm antibiotics, 0 detectable pathogens/L
- : Grade A organic fertilizer (NPK 4-3-3)
- : Zero-residue certification compliant
Energy-Smart Implementation Architecture
