Flocculating particles
WebFlocculation is a two-step particle aggregation process in which a large number of small particles form a small number large flocs. Step 1: Coagulation Small particles usually … WebThis is primarily due to the individual particles flocculating into larger aggregates which are significantly less dense than their component primary particles. An individual floc may constitute up to 10 6 individual particles, and flocculation is a dynamically active process which is directly affected by its environmental conditions; this ...
