Abstract

Textile industries are widespread in several European countries and are characterized by the release of a huge amount of high polluted wastewaters. Indeed, deying processes use a high specific water stream at large concentration of polluting dyes of different types. Moreover, the spectrum of pollutants – species and concentration - fluctuates during the production cycle. To fulfil environmental regulations, conventional chemical, physical and biological treatments are often not sufficient. Therefore, expensive tertiary processes – e.g. ozonozation and adsorption - are required. Present contribution reports about the charcaterization of the biosoption process carried out with dehydrated C. elegans (provided by the Mycotheca Universitatis Taurinensis of the University of Turin) biomass. The attention was focused on adsorption of blue acid dye Abu-62. Adsorption isotherms were assessed at temperatures ranging between 4 and 50°C by means of tests performed under batch conditions. A fixed bed bench-scale unit was used for biosorption kinetic assessment.
