Definitions
- Coagulation and flocculation are well known processes for the removal of suspended matter. Coagulation may be viewed as the initial process of destabilizing or neutralizing charges on suspended particles so that they begin to aggregate. Coagulation is usually combined with flocculation, sedimentation, or filtration. Flocculation is the aggregation of the particles into larger masses.
- metal salts such as polyaluminum chlorides, aluminum sulfate, ferric sulfate, and ferric chloride.
- Chitosan is a polymer derived from naturally occurring chitin.
- Chitin is a linear polysaccharide composed of ⁇ -(1-4)-linked 2-acetoamido-2-deoxy-D-glucose units that occur naturally in the exoskeleton of invertebrates, in particular, the carapace of marine crustaceans.

Although the combination may offer improved coagulation, flocculation and floc size, the resulting floccules may still exhibit low shear strength and come apart when subjected to low to moderate pressure or agitation. Improved backwashing of filters containing flocculated insoluble materials that do not cling to the filter media but release easily from the filter media during backwashing cycles would be of significant value.
