ISO/TC 281 Fine Bubble Technology
Next week (24-25 November) sees the UK host an ISO meeting for Technical Committee 281 in fine and ultrafine bubbles. These are bubbles <100 micron in size and have many applications.
Fine bubbles (1- 100 microns) have many applications including water treatment, medical imaging and drug delivery. Ultra fine bubbles (<100 nm) are used in cleaning, food, agricultural and aqua cultural applications. The new technologies available here are increasing in use; for example, many new washing machines have bubble generators in them for enhanced cleaning.
There is a large increase in applications globally with a lot of this interest being in ultrafine bubbles – the existence of which have not yet been fully validated or understood theoretically – although I’ve seen so much practical evidence that I definitely believe they are there!
The ISO group has three working groups concerned with:
- the definitions and measurement / parameters used,
- the techniques used to characterize the bubbles,
- the applications.
If any of you reading this are involved in any aspects of fine / ultrafine bubble technology please get in touch, we are always interested in new experts from different countries who are able to get involved in the standardization process in this area.
