About This Item
TS ISO 20480-4 is a terminology standard within fine bubble technology, focused on terms related to microbubble beds. In particular, it establishes a common vocabulary for the bubble bed and its characteristics in the dissolved air flotation (DAF) process, helping users describe the same technical concepts consistently across documents and applications.
Microbubble beds in the DAF context
In general technical terms, microbubbles are very small gas bubbles used to increase interfacial area and support separation or lifting effects in a liquid. In DAF systems, they help carry suspended solids or oily contaminants to the surface for removal. The emphasis of this part is not on equipment design or process control, but on clarifying the terminology used to describe that bubble structure and its related features.
Why the terminology matters
In fine bubble technology, terms such as “bubble bed,” “microbubble,” and “characteristics” are used to distinguish differences in bubble size, distribution, density, and behavior. A controlled vocabulary reduces ambiguity in laboratory reports, process documentation, equipment descriptions, and technical communication. This part is limited to terms associated with the DAF bubble bed and its characteristics; it does not by itself define the full range of fine bubble applications or establish performance requirements.
- Provides a shared reference for terminology used in dissolved air flotation (DAF).
- Names and distinguishes characteristics of the microbubble bed.
- Supports clearer technical communication and documentation in fine bubble technology.
