This water is unlikely to cause water pollution problems if it is returned to the sintering plant along with the collected dust. When a scrubber or a wet ESP is used as a control technique, the attendant wastewater must be treated and controlled. The wet scrubber could be a major source of water pollution if the effluent were not controlled.

In this scenario, Dust collection System becomes a must-have facility to be required at metal and steel power plants in order to protect its workers from any hazard. Prolonged exposure to flames and dust is too perilous for any worker and hence proper facilities for dust collection must be ensured in order to safeguard their health.
