B.O.D PLANT:

          Liquor from tar and Benzol plant are toxic. Feeding directly into river or atmosphere may seriously damage the ecological balance; so they are treated with bacteria and then disposed off.

          NEW SYSTEMS:

1.     Electrically driven exhauster with steam drive as stand by.

2.     Auto-operation of cooling tower pumps, with the help of level switch.

Tarry liquor flushing in primary coolers.
