This presentation discusses thermal pollution, which is defined as a sudden increase or decrease in the temperature of a natural body of water caused by human activity. The document outlines various causes of thermal pollution including power plants, industrial facilities, soil erosion, and hydroelectric power generation. Effects of thermal pollution include reduced dissolved oxygen, changes in water properties, increased toxicity, and disruption of biological activities and damage to organisms. Control measures that can help mitigate thermal pollution are also presented such as cooling towers, cooling ponds, spray ponds, and artificial lakes. The document concludes with suggestions for individuals and students to help prevent thermal pollution through education and awareness efforts.

2. Introduction
What is thermal pollution?
Thermal pollution is defined as sudden increase or decrease in
temperature of a natural body of water which may be ocean, lake, river
or pond by human influence.

3. Causes of Thermal Pollution
Power, Industrial, and Manufacturing Plants
Soil Erosion Hydroelectric Power Generation Natural Cause

4. Waste Heat from Power Plants

5. Dissolved Oxygen vs Temp

6. Fish Oxygen Use vs Temperature

7. Cause of Thermal Pollution in Bangladesh
Industrial Effluents Domestic Sewages Use of Extensive
Amount of Fertilizing
Chemicals
Deforestation

8. Waste from Textile Industry

9. Use of Fertilizer

11. The Harmful Effects Of The Thermal Pollution
1. Reduction in dissolved Oxygen
2. Change in water properties
3. Increase in toxicity
4. Disruption of Biological activities
5. Damage of biotic organism

12. Control Measures
• Cooling Tower
• Cooling ponds
• Spray ponds
• Artificial lakes

13. What I can do to prevent Thermal pollution:
1. Introduce thermal pollution to my family.
2. Then to my relatives.
3. Ask my friends to help me spread the information of thermal
pollution
4. With the help of elders talk with the farmers of my village to reduce
the excessive use of Chemicals and fertilizer on the fields.

14. What we can do to prevent thermal pollution
as a group or as students of BUFT:
1. Create a club on Environment pollution
2. Organize seminars, different programs on environment pollution to
increase public awareness.
3. Go to different universities to increase student awareness.
4. Inspire people and plant trees near ponds and revers.
