Reciclado de aguas residuales textiles decoloradas con técnicas electroquímicas

Mª Carmen Gutiérrez Bouzán


This work deals with the possibility of recycling textile wastewater for use in the dyeing process. Until now, colour produced by the presence of reactive dyes was removed by means of an electrochemical treatment with cell ECO 75 (ELCHEM). The structure of the cell is described in detail. The electrochemical treatment is applied to the decolorisation of diverse synthetic wastewaters. Decolorisation yield and electrical consumption are studied. Later, treated waters are submitted to a
stripping process in order to remove residual chlorine, and they are then employed for cotton dyeing. The dyed samples are compared.
