Contact SupplierThe effluent from the dye/dye intermediate industries containing a mix of organic and inorganic salts is treated using Evaporation and Drying Technology to separate the organic and inorganic salts. The organic salts are used as a solid fuel and the inorganic salt can be a marketable product. The scheme shown above depicts that the effluent is crystallized at first and after centrifuging, the concentrate from the centrifuge comprising organic salts is concentrated using evaporator and then the concentrate is dried using the Agitated Thin Film Dryer or Spray Dryer.
On the other hand, the inorganic salts obtained after centrifuging are melted and treated with Activated Carbon. After separation of carbon from the slurry, the resulting slurry is concentrated using an Evaporator. The concentrate from this evaporator is passed through Centrifuge to obtain inorganic salts with high purity. The salt obtained from the centrifuge now can be dried using a Fluidized Bed Dryer.
