Abstract

Overview

ISO 21255:2018 establishes international standards for the storage and transportation of ultrafine bubble dispersions (UFBD) in water, providing essential guidelines to maintain the quality and stability of these dispersions. Ultrafine bubbles-also known as nanobubbles-have unique properties that make them valuable across various industries, including agriculture, semiconductor manufacturing, water treatment, and surface cleaning.

This standard specifies the necessary procedures, equipment, and environmental conditions required to preserve critical characteristics of the ultrafine bubbles, such as size and number concentration. By ensuring integrity during storage and transport, ISO 21255:2018 supports the expansion of fine bubble technology applications beyond on-site generation and use.

Key Topics

Ultrafine Bubble Dispersion (UFBD): Defined as liquid containing ultrafine bubbles in water, requiring specific handling to preserve bubble stability.
Storage Substances: Requirements emphasize using grade 1, 2, or 3 water (per ISO 3696) free from chemically active or bacterial contaminants that could alter UFBD properties.
Containers and Filling Procedures:
- Use rigid containers to minimize contact with air and mechanical disturbances.
- Recommended container material is borosilicate glass 3.3 (ISO 3585) for its stability and inertness.
- Interfaces should use low gas-permeable flexible materials like poly(isobutylene-isoprene) (IIR) to accommodate pressure changes without bubble deterioration.
- Ensure sterilization (heat or UV) to avoid biological contamination.
Storage Conditions:
- Maintain temperature between 5 °C and 35 °C; avoid freezing (
