    Coagulation an overview ScienceDirect Topics

    Coagulation concentrations are the electrolyte concentrations required just to coagulate a sol. Clearly V M in Figure 5.9 must be reduced, preferably to zero, to allow coagulation to occur. This can be achieved by increasing the ionic strength of the solution, thus increasing k and thereby reducing VR in equation 5.16.The addition of salts with multivalent ions (such as Al 3+, Ca 2+, Fe 3+) is

    Coagulation-Flocculation SSWM Find tools

    Coagulation-flocculation is a chemical water treatment technique typically applied prior to sedimentation and filtration (e.g. rapid sand filtration) to enhance the ability of a treatment process to remove particles. Coagulation is a process used to neutralise charges and form a gelatinous mass to trap (or bridge) particles thus forming a mass large enough to settle or be trapped in the filter.
