Prospects of Using Complex Coagulation Systems Based on Chitosan in Water treatment Processes

Nowadays involving environmentally friendly reagents and materials is gaining additional importance in water treatment processes, especially if we take into consideration the latest developments in science. Aluminium sulfate, aluminium chloride and ferric chloride are widely used in coagulation processes, however, as a result of involving these coagulants the concentration of metal ions dissolved in water increases. Therefore, it is advisable to give preference to inorganic coagulants in combination with synthetic or natural flocculants. Due to the growing demand for environmentally friendly materials it could be advisable to use flocculants based on chitosan in order to improve the coagulation and flocculation processes. Chitosan, which is a polysaccharide produced by chitin deacetylation, is a positively charged natural and non-toxic polyelectrolyte widely used in the flocculation of negatively charged suspended particles in water treatment. Therefore, studying and developing effective complex coagulants that could replace conventional coagulation systems becomes a topical problem nowadays. In this research we analyzed the optimum dosage and pH of complex coagulation systems with chitosan using Jar test methodology
