Flocculation (except in polymer science) Process of contact and adhesion whereby dispersed molecules or particles are held together by weak physical interactions ultimately leading to phase separation by the formation of precipitates of larger than colloidal size. Note 1: In contrast to aggregation, … See more Flocculation, in the field of chemistry, is a process by which colloidal particles come out of suspension to sediment under the form of floc or flake, either spontaneously or due to the addition of a clarifying agent. The action differs from See more According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". Flocculation is synonymous with agglomeration and coagulation / coalescence See more Deflocculation is the exact opposite of flocculation, also sometimes known as peptization. Sodium silicate (Na2SiO3) is a typical example. … See more • John Gregory (2006), Particles in water: properties and processes, Taylor & Francis, ISBN 1-58716-085-4 • John C. Crittenden, R.

Separation of diaspore from bauxite by selective flocculation …

WebFlocculation is a physical process that promotes the formation of larger particles by gentle mixing. Alum (an aluminum salt), lime (alkaline chemicals principally containing calcium or magnesium with oxygen), or iron salts are commonly used coagulants. Alum is nontoxic and used in the food industry for pickling. WebFlocculation of kaolin suspensions using ternary polymerization flocculant (CAS) synthesized by chitosan (CTS), acrylamide and ethyl acrylate quaternary ammonium salt was investigated in lab-scale. It was found that CAS had more advantages such as higher flocculation efficiency, lesser dosage and wider pH flocculation range than CTS. dachlast caddy

flocculation - Chinese translation – Linguee

WebFlocculation is either induced (with the addition of flocculating agents) or naturally happens (due to the production of the flocculating chemical by microalgal cells). Auto flocculation occurs due to the increase in pH. Sometimes, it can be a consequence of the interaction of contaminating species with microalgae. WebApr 15, 2024 · Section snippets Cell culture.
