Fine bubble technologies offer performance enhancement in a number of processes and applications such as cleaning, aquaculture and agriculture.
Characterization of ultrafine bubbles is critical to the further development of industrial applications. A number of characteristics such as bubble size, bubble number stability, bubble number concentrationas well as other physical and chemical characteristics are important in such applications. In order to provide a verifiable characterization platform for these applications, a set of sampling and sample preparation procedures has been developed. This approach results in the most reliable correlation between the characteristics of the fine bubbles in dispersion and their application effectiveness.
It is commonly accepted that the sample preparation technique will depend on the characterization technique used.
BS ISO 20298-1:2018 specifies procedures and requirements for sampling and sample preparation of ultrafine bubble dispersions in water.
This procedure is applicable to static samples such as those contained in a tank. It is not applicable to
running or flowing samples.
