The emulsion stabilizing potential of chitosans was compared in the presence of organicadditives. The 4 types suspension of 0.1 wt% of chitosan flocculant were obtained by mixing ofchitosan colloidal dispersion with three kinds of additives; sorbic acid, benzoic acid anddibutylhydroxytoluene (BHT). The viscosity of emulsion revealed the following order of stabilizingpotentials; sorbic acid 〉 benzoic acid 〉 BHT. As a bio-adsorbent for the treatment of biomedicalwastewater, the results were capable of adsorbing more than 30% of pure chitosan. The chitosanemulsions represented that the removal efficiency were increased by COD 59.2%, BOD 70.1%, Zn77.1%, Cu 93.7%, E. coli 99.4%. As a result of this investigation, it is remarked that the highstabilizing potential of chitosan solution is explained by higher adsorption efficiency with organics,heavy metals and microorganism, and that the effectiveness of chitosan solution for coagulatingbiomedical wastewater suspension could be improved due to stabilization of the viscosity in thepresence of organic additives
