Flocculation Basics in Processing

23 December, 2012 Posted by Christopher Jenner
Following or during coagulation another process known as flocculation occurs. In flocculation the primary means of attraction is by weak van der Wall’s forces. These forces are encouraged through increased retention time and decreased mixing energy. The process yields particles that are visible to the naked eye, unlike coagulation which yields microscopic microflock’s. In flocculation […] Read more»

Coagulation Basics in Processing

23 December, 2012 Posted by Christopher Jenner
Coagulation is used in a number of industries ranging from mining to chemicals production. Its primary purpose is to reduce turbidity in process water. In coal processing a coagulant is added to clear any undesirable microscopic particles (clays etc.) from the process water and hence enables recirculation within the plant. The fundamental purpose of coagulation […] Read more»
