EFFLUENT FROM TEXTILE DYEING INDUSTRIES


The effluent from the Textile Dyeing Industries generally consists of high amount of inorganic salts like sodium sulphate or sodium chloride. For the purpose of treating this effluent, first Evaporation, then Crystallization of Salts and thereafter centrifuging is done to dewater the salt output from crystallizer. A combination of Industrial Evaporators like Falling film Evaporator, Forced Circulation Evaporator and the Industrial Dryers like Agitated Thin Film Dryer, Fluid Bed Dryer etc are used. Other auxiliary techniques such as centrifuging are also employed.

The effluent containing high amount of inorganic salts is preheated and then it enters the multiple effects falling film evaporator for further concentration. In the evaporation process where the concentration is done to a level close to the saturation point of the salt present.

After concentration in the falling film evaporator, we get a concentrated stream of effluent which can be then further fed to the evaporative/cooling crystallizer where evaporation/cooling encourage the crystallization process.

Finally, the output from the crystallizer centrifuged to separate the salts from the stream. The salt after centrifuging can further be dried using a Fluid Bed Dryer.


Effluent Treatment

TEXTILE WASTE WATER HANDLING BY EVAPORATION AND SOLID SEPARATION BASIC PRINCIPLE:
The technology is based on basic principle of reduction of quantity by concentrating the effluent and subsequently separation of salt and water.
