DEFINITION

Classification: 204/573

Resolving emulsion or dispersion:

(under subclass 554) 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.
