The chemist flocculated the particles in the beaker.

Definition

1. Verb (transitive):

   • To cause (fine particles or a suspension) to aggregate into small, loose, woolly-looking clusters or lumps.
   • To convert a finely divided or colloidal suspension into a flocculent mass.

2. Verb (intransitive):

   • To form or collect into such small, loose, woolly-looking clusters or lumps.
   • To aggregate into a flocculent mass.

Usage and Examples

• Transitive Verb:

  • The water treatment process uses alum to flocculate the impurities.
  • In the experiment, we added a polymer to flocculate the suspended clay particles.

• Intransitive Verb:

  • Over time, the fine sediment began to flocculate and settle at the bottom of the beaker.
  • The colloidal particles will flocculate if the pH of the solution is adjusted correctly.

Advanced Usage

• Technical Context: The term is primarily used in scientific and industrial fields such as chemistry, environmental engineering, and wastewater treatment. It describes a specific physical process of aggregation.
  • The goal of the coagulation stage is to flocculate the microscopic contaminants so they can be removed by filtration.

Variants and Related Words
