Reduction Of Waste Concentration By Recovery and Reuse Of Chemicals

From the view point of possible reduction of waste load,following points need attention:
1.Recovery of caustic soda from mercerising wash waters and the reuse after evaporation and concentration
   is a  very vital factor. Most of the composite mills have realised its importance and related economics,and have    successfully adopted it with advantage.
2.Recovery of wool grease in wool scouring by crocking,centri fuging of solvent extraction in important
   in woolen industry.
3.Use of standing bath in dyeing in possible for several dyes and should be practiced.
4.Finishing left-overs should be collected and put to reuse for finishing of either same sort later on or finishing
   other sorts after suitable adjustment.
5.Possibility of reusing from carbonising should be explored.
6.Synthetic sizing agents can be recovered from desizing both my suitable method and can be reused for
    sizing along with fresh size.
