The process of removal of natural colouring matter and add-ons from raw materials prior to release is referred to as scouring and bleaching. De-colouring chemicals including polyacrylic acid, hydrogen peroxide, etc., help in the process of decolourization of waste material into a suitable processing material through the processes of oxidative and reductive bleaching. Decolourizing or bleaching of wastewater is one of the critical stages involved in the processing of the same.
Effective quarternary polymer for removal of colour in textiles, pulp & paper, dyeing industries. It acts as a decolourizing agent, decreasing COD value, with colour removal for viscous waste water.
