Effluent Management (EN12)
Wastewater from process was
treated with best available
physio-chemical methods and
recycled in the process.
Wastewater from the coke plant
was treated biologically where
organic pollutants are oxidized
and decomposed by
microorganisms.
The absolute effluent quantities
and pollution loads from the
Steel Works are furnished in
Table-5.23. The levels of total
pollutant discharge in the
wastewater streams have reduced
considerably at various
locations as shown in the
Fig.5.27, 5.28 & 5.29.
Noamundi and Joda Iron Mines &
Collieries at West Bokaro and
Jharia do not discharge any
overflow from the Slime/Tailing
Dams. The quality of the treated
effluent discharged from the
Jharia Group of Collieries is
presented in Table 5.24. |
