The optimized airlift structure improves gas-liquid mass transfer and oxygen distribution throughout the vessel.

Advantages include:

• High oxygen transfer efficiency

• Uniform dissolved oxygen distribution

• Enhanced nutrient circulation

• Stable cell growth environment

This helps improve biomass productivity and cultivation performance.

Energy-Efficient Operation

Without large mechanical agitators, the system consumes less energy and generates less heat during operation.

Benefits include:

• Lower operating costs

• Reduced maintenance requirements

• Minimal heat accumulation

• Simplified operation

This makes the system suitable for continuous laboratory and pilot-scale operation.

Hygienic & Simplified Structure
