How does nano bubble generator work ?
② The micro nano bubbles are injected into the sewage at a high speed to cause mechanical ionization of the sewage. The hydroxyl radicals released when the micro bubbles break, combined with the comprehensive effect of active oxygen and oxygen ions, completely decompose and oxidize the pollutants into small molecules without pollution and toxic side effects.

Basic Data
- Stocking Density
- Quantity: 500 ind/m³
- Biomass: 20 kg/m³ (high‑density culture)
- DO requirement: ≥ 5–7 mg/L
- Total shrimp biomass: 1280 kg
- Oxygen Demand
- Standard: 0.15–0.20 g O₂/(kg·h)
- Calculated: 230.4 g O₂/h (0.23 kg/h)
- With safety factor (1.5–2×): 0.35–0.5 kg O₂/h
- Equipment Recommendation
- Oxygen generator: ≥ 0.4 kg/h
- Suggested: 10 L/min industrial oxygen generator
- Matching: nano bubble generator / oxygen cone
- Online DO meter recommended (alarm below 5 mg/L)
