Question

What measures you would suggest to prevent thermal pollution?

Answer 1

1. Cool water before discharge: Use cooling towers or cooling ponds to lower the temperature of heated water before releasing it into a natural water body.
2. Recycle cooling water: Reuse heated water within the plant, or cool it and circulate it again, instead of frequently discharging it into rivers or lakes.
3. Follow discharge standards: Monitor the temperature of industrial effluents and ensure that they meet prescribed limits before discharge.
4. Use waste heat productively: Where possible, use the heat for other industrial processes or heating rather than releasing it into the environment.
5. Protect vegetation near water bodies: Maintain trees and natural vegetation along riverbanks to provide shade and help limit warming.
6. Treat domestic and industrial wastewater: Treat wastewater appropriately and manage its discharge so it does not cause sudden temperature changes in aquatic habitats.
