Chitosan is a coagulant/flocculant in water treatment with the treatment efficiency for particulate material of 99% or higher. It is a good alternative to the traditional metal-based coagulants as the problem of metal residues is avoided. Besides, the sludge volume is reduced by approximately 50% when chitosan is used, and absence of the metal

For humic materials, Guibal et al. showed that chitosan can be used as a primary coagulant or as a flocculant after coagulation: it has characteristics of both coagulants and flocculants. Ahmad et al. [91] demonstrated it was a very effective coagulant to remove the residual oil content from palm oil mill effluent compared to alum and PAC.

However, in this experiment, as shown in figure 7, the curves were not monotonic. When the dose was increased above the optimal dose, flocculation deteriorated [1-3]. However, further increasing the dose promotes flocculation [9]. Chitosan flocculant seems to have the unique characteristic that a waveform appears in the flocculationwindow curve.
