Title:

Coal Mine Water Reclamation

Value Proposition:

Purification of coal impacted water to be fit for drinking

Summary Application:

Coalmine water reclamation process developed at NML has three modules arranged sequentially, It separates suspended particulate matters using appropriate flocculants, negotiates dissolved contaminants including heavy metal ions with a nanometric aqueous suspension developed that kills harmful micro-organisms through ozonation, The finished product is suitable for the purpose of drinking, the plant developed to perform on Continuous mode @ 4000-5000 LPH that can operate for 20 hours per day.

Advantages:
  • The process provides reclamation of coalmine water free of harmful micro-organisms suitable for the purpose of drinking.
  • The purified water cost works out to be less than 20 paisa per litre.
  • The process is environment friendly and does not involve any hazardous or toxic reagents.
