"Fine bubbles (FB)" refers to a collective term for tiny bubbles smaller than 100μm. This document is a technical proposal introducing the efficiency improvements in water environments and aquatic resources through fine bubbles. It includes a wealth of information such as "initiatives in environmental business," "reference data on fine bubble (FB) bubble sizes," and "expected effects from system implementation." We also introduce our lineup of fine bubble products, so please take a moment to read through it.

The document includes applications and case studies of "fine bubble technology," as well as fine bubble generation nozzles. Fine bubbles refer to a collective term for tiny bubbles smaller than 100μm. Bubbles approximately smaller than 60μm exhibit significant behavior of shrinking in water due to the surface tension at the water-bubble interface, ultimately collapsing (dissolving or disappearing) in the water. This phenomenon alters the physical properties of water. 【Contents】 ■ What are fine bubbles? ■ Applications of fine bubbles ■ Case studies - Seaweed quality improvement system - Shrimp productivity enhancement system - Cleaning field ■ Fine bubble generation nozzles *For more details, please refer to the PDF document or feel free to contact us.

Our company is developing a generation device for fine bubbles, which are functional microbubbles. There have been numerous reports that using water or seawater generated with fine bubbles enhances physiological activity in living organisms. By applying a specified water flow to the fine bubble generation nozzle, air is self-suctioned into the nozzle, and the sucked-in air is transformed into fine bubbles due to the shear force generated within the nozzle. Please feel free to contact us for more information. *For more details, please download the PDF or feel free to reach out to us.*
