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»
