Nakajima-style fine bubble equipment + oxygen for resilient wastewater treatment against load fluctuations.
We aim to create a dissolved oxygen environment where microorganisms can thrive, improving treatment capacity, stability, and sludge management.
Main effects of introducing fine bubbles in shrimp farming.
Effects of Introducing Fine Bubbles in Shrimp Farming The introduction of fine bubbles for oxygen supply and water circulation is expected to yield the following effects: - Stabilization of DO (dissolved oxygen): Measures against oxygen deficiency that tends to occur at night, early morning, or in the bottom layers. - Reduction of low oxygen stress: Improving the respiratory environment for shrimp, supporting feeding and molting. - Uniformity in growth and size: Potential to reduce growth variability through stabilization of DO and water quality. - Improvement of FCR (feed conversion ratio): Enhancing feeding conditions to support better feed utilization efficiency. - Measures against ammonia and nitrite: Supporting water quality management that utilizes oxygen by nitrifying bacteria. - Improvement of water exchange and sediment management: Potential to mitigate water quality deterioration associated with oxygen deficiency and accumulation of organic matter in the bottom layers.
Purification effect using fine bubble technology
Fine bubbles and purification effects The adsorption properties of fine bubbles are due to their surfaces being negatively charged (zeta potential). In negatively charged FB water, the surfaces attract positively charged substances (ions).
