Sažetak
Like any other industrial effluent textile wastewater holds certain particularities in the presence of contaminants, which distinguishes both treatment of such effluents and removal of harmful auxiliaries and aiding agents used in textile preparation, production and finishing processes. Long lists of additives, labeled as impurities to be removed after completion of production processes, starts with textile dyes, which used even in low concentrations produce undesirable brightly colored effluents. Acids and alkali are imperatively neutralized, thus avoiding elevation of pH levels in receiving waters or aquifers. Specific operations like reactive dyeing may require employment of large quantities of salts (usually sodium chloride and sodium sulphate), which may cause elevation of electrolyte level in effluents. Detergents and other surfactants may cause eutrophication, thus like all here listed auxiliaries demanding removal from effluents prior to release. Treatment methods are mandatory in order of achieving proper level of legislatively demanded effluent purity. In this paper a rather inexpensive treatment method of biosorption is described along with the construction of model column. Described treatment process belongs to a group of column techniques in which layers of adsorbents are arranged on top of each other forming a vertical treatment medium. Adsorbents were used based on their accessibility in the region and price, regarding the end result of facilitation of a real scale pilot project. Pilot project would be appropriate treatment solution of effluent waste wasters for textile based SMEs as well as for domestic households.
