POSSIBILITY OF ELIMINATION OF ORGANIC MATERIAL TYPE HUMIC ADSORPTION ON DIFFERENT MATERIALS OF A WATER SURFACE AREA OF BEJAIA Amimeur Djamel*, Guergazi Saâdia** , Achour Samia*** *University Abderrahmane Mira, Bejaia Abstract In surface water to be processed, and distributed for consumption potabilisées, organic matter is a constituent feature of their physico-chemical quality. It can result from degradation of plant and animal products and human activities and emissions. Organic compounds of natural origin comprise the majority of the organic load of these waters. Among these compounds, we find humic substances (major fraction of natural organic matter) that are the subject of special attention in the field of water treatment due to their potential to form halogenated organic compounds are often toxic (mutagenic and carcinogenic effects). It must be disposed of to meet the water quality required by regulations. Several treatment processes have been aimed at elimination of organic matter which adsorption can significantly contribute to the elimination of dissolved organic compounds, or even semi-colloid. The adsorbent materials may then take place at two levels, during the clarification phase or as polishing treatment, in filter beds before the disinfection phase, the end of treatment before distribution. The main adsorbents used in water treatment are porous materials such as activated carbon, activated alumina, clays, and certain synthetic resins. Keywords: water, humic adsorption, organic material |
