DEFINITION

Classification: 204/563

Resolving emulsion or dispersion:

(under subclass 559) Process which involves breaking an emulsion or dispersion by agglomerating or accreting suspended constituents.

(1) Note. The emulsion or dispersion may either be

initially present or formed during a previous process step.
