Application of the natural cellulosic supports modified chemically for the treatment of the industrial effluents

The process of purification and discoloration of industrial waters (and particularly effluents of the textile industry) can meet major difficulties: certain dyes agents get through the devices of purge without being to stop. the cost of equipment and products of purification is prohibitive. Finally, in many cases, the discoloration can be only partial because waters to be treated containing mixtures of dyes of different nature, the material of purification can be effective only screw/screw of some of them.
