What are the ways of treating industrial effluents?

To minimize the effects of pollution The hot waters and effluents could be treated before releasing it into the rivers.

This treatment could be done in 3 phases:


1. Primary treatment: By using mechanical means like screening, grinding, flocculation, and sedimentation. Here the solids are separated from the wastewater stream.


2. Secondary treatment: Using the biological process. The dissolved biological matter is progressively converted into a solid mass by using indigenous, water-borne micro-organisms.


3. Tertiary: The wastewater is recycled in the tertiary stage.
