Abstract

The article has investigated restoration of the concentrated salt solution from wastewaters of the dye bath for its repeated use in textile industry. We have detected structural and electrostatic influence of dye molecules on retention of the dye and restoration of concentrated salt solution by the method of nanofiltration. Dyes containing sulfated and carboxylated functional groups with a different charge and molecular weight were used.
