Indian Institute of Chemical Technology (IICT)
About
Removal of excess chloride and cyanide from industrial waste water.
Designed, developed and commissioned NF system of 5000 L/h capacity for the removal of the cyanide and excess chloride.
The process enables separation of chloride from 1500 mg/L in the effluent, to an acceptable level of 500 mg/L with a water recovery of 85%.
The reject of 15% rich in Chloride would be treated by the conventional coagulation process.
Outcome / Output
The process is more economical when compared to reverse osmosis and other conventional processes.
