An Analysis of Floc Separation Characteristics in Chemical Wastewater Treatment
Chemical treatment of wastewater consists of three unit processes: coagulation/precipitation, flocculation and floc separation, the latter normally being carried out by sedimentation. The reaction step (coagulation/precipitation) is obviously of fundamental importance to the total treatment result, but the separation steps (flocculation and floc separation) have far greater importance from an economic point of view, since separation normally takes hours to complete while the reaction is completed within seconds.
