What are the control measures of thermal pollution?

What are the control measures of thermal pollution?

How can thermal pollution be prevented?

• Heated water from the industries can treated before discharging directly to the water bodies.
• Heated water from the industries can be treated by the installation of cooling ponds and cooling towers.
• Industrial treated water can be recycled for domestic use or industrial heating.

What are the causes and effects of thermal pollution?

Thermal pollution also has some natural causes. Geothermal vents and hot springs introduce excess heat into bodies of water. Soil erosion, deforestation, and runoff from paved areas are other artificial sources of hot water. Deforestation eliminates shade, which exposes the water to sunlight.

What is thermal pollution Slideshare?

Thermal Pollution • Thermal Pollution is the harmful increase in water temperature in streams, rivers, lakes, or occasionally, coastal ocean waters. • It is the degradation of water quality by any process that changes ambient water temperature.

What are 5 causes of thermal pollution?

What are five causes of thermal pollution?

• #1. Use of water as a cooling agent in industrial plants.
• #2. Soil erosion.
• #3. Runoff from paved surfaces.
• #4. Natural causes.
• #5. Deforestation.
• #1. Decrease in dissolved oxygen (DO) levels.
• #2. Increase in toxins.
• #3. Ecological impact.

What are the causes effects and control measures of marine pollution?

The marine environment becomes polluted and contaminated through various sources and forms. Major sources of marine pollution are the inflow of chemicals, solid waste, discharge of radioactive elements, industrial and agricultural effluents, man-made sedimentation, oil spills, and many such factors.

What are the five causes of thermal pollution?

What is the major cause of thermal pollution?

A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects the ecosystem.

What is the major cause of thermal pollution Class 10?

The main causes of thermal pollutions are – water is used as a cooling agent in power plants and manufacturing industries, soil erosion, deforestation – as forests help to cool down the temperature of the earth, natural causes like volcanoes, geothermal vents, hot springs; and disposal of domestic sewages on water …

What is an example of thermal pollution?

An example of thermal pollution is a factory that uses water for cooling then releases warm water back into a natural body of water without treating it first. Another example of thermal pollution is soil erosion. Soil erosion causes bodies of water to be more exposed to sunlight, thus increasing the temperature.

What are the effects of thermal pollution on biodiversity?

Biodiversity can be decreased as a result. High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions. This can lead to increased bacteria levels when there is ample food supply. Many aquatic species will fail to reproduce at elevated temperatures.

What is thermal pollution class 9?

Thermal pollution can be defined as a rise in the temperature of water bodies largely due to human activities. Thermal power plants use water as a cooling agent in their plants. When these plants release recycled hot water into the rivers, temperature of water rises resulting in thermal pollution.

What are the effects of thermal pollution on water?

Reduced solubility of oxygen – Reduced solubility of oxygen in water bodies is another disappointing effect of thermal pollution. This less solubility of oxygen in water mainly affects the metabolism of water animal. Adverse effect on water plants – Change in temperature levels is extremely harmful for the aquatic plants.

How do poor farming practices lead to thermal pollution?

Poor farming Practices also lead to thermal polloution Reduction in dissolved oxygen: Concentration of Dissolved Oxygen (DO) decreases with increase in temperature. Increase in toxicity: The rising temperature increases the toxicity of the poison present in water.

How do plants and trees help to prevent thermal pollution?

Trees & plants protect direct exposure of sunlight on lakes, ponds, rivers, etc. When these water bodies are exposed to sunlight, they start absorbing more heat resulting in thermal pollution. Deforestation also contributes to greenhouse effects causing global warming, which is again helping to thermal pollution.

How does deforestation cause thermal pollution?

Deforestation also contributes to greenhouse effects causing global warming, which is again helping to thermal pollution. Some natural causes like geothermal activity & active volcanoes below oceans & seas also trigger the natural underground heating of the water bodies.
