What are the source and effect 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 are the sources of thermal pollution explain it?
The major sources of thermal pollution are heated waste water produced from production and manufacturing plants – coal fired thermal power plants, natural gas plants, nuclear plants, textiles, paper and pulp industries, etc.
What is the greatest source of thermal pollution?
The single biggest cause of thermal pollution is probably cooling for industrial machinery and power plants. Water is an excellent, and free, cooling agent.
Which of the following method can be used to control thermal pollution?
Cooling ponds or reservoirs constitute the simplest method of controlling thermal discharges. Heated effluents on the surface of water in cooling ponds maximize dissipation of heat to the atmosphere and minimize the water area and volume.
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.
How can we prevent 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.
How can we manage thermal pollution?
Solutions to thermal pollution include altering environment of watercourse, ooling the water in cooling towers before it is released into the environment, and adding or removing heat. Shade trees around waterways and coastal locations help to lower temperatures by blocking the sun’s rays and absorbing carbon emissions.
What are the examples 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 types of thermal pollution?
What are the sources of Thermal Pollution?
- Nuclear Power Plant.
- Coal-fired power Plant.
- Industrial Effluents.
- Domestic Sewage.
- Hydro-electric power.
- Thermal Power Plant.
What is an example of thermal pollution?
What are two major causes of thermal pollution?
Causes of Thermal Pollution
- Water as a Cooling Agent in Power, Manufacturing and Industrial Plants. Production and Manufacturing plants are the biggest sources of thermal pollution.
- Soil Erosion.
- Runoff From Paved Surfaces.
- Natural Causes.
- Retention Ponds.
- Domestic Sewage.
How to prevent or control high temperature caused by thermal pollution?
The following measures can be taken to prevent or control high temperature caused by thermal pollution: 1. Heated water from the industries can treated before discharging directly to the water bodies. 2. Heated water from the industries can be treated by the installation of cooling ponds and cooling towers. 3.
How does thermal pollution affect the aquatic system?
The effect of thermal pollution is more prominently marked in aquatic system. The industries like iron and steel plants, petroleum refineries, nuclear reactors, electric power plants etc. use large amount of water for cooling purposes.
How can thermal pollution be controlled in a pond?
Thermal pollution can be controlled by passing the heated water through a cooling pond or a cooling tower after it leaves the condenser. One method is to construct a large shallow pond. Hot water is pumped into one end of pond and cooler water is removed from the other end. Another method is using a cooling tower. b.
How are nuclear power plants related to thermal pollution?
Nuclear power plants release a massive amount of unutilized heat & harmful radioactive waste into nearby water bodies, causing an increase in water temperature. Emissions from nuclear reactors & processing installations are also contributing to thermal pollution by increasing the temperature of water bodies.
