Essay On Thermal Pollution

Thermal pollution can be simply explained as the addition of surplus heat to water and ejecting it back to the water bodies. So how does it happen? Well, numerous industries take water from natural water resources for their industrial purposes. Maximum of this water is used as coolant as it is used to cool down the machines of any factory or plant.

Afterwards, this used water with altered and much high temperature is ejected back to the natural resources including lakes, ponds, seas, etc. This causes sudden increase in temperature of natural water bodies too. The altered water also creates disturbance in the oxygen level of water bodies. This in turn, harms the marine life and local ecosystems. Therefore, thermal pollution caused in water

Even after knowing the hazardous effects of thermal pollution on environment, there are abundant industries which are continuously using ways that encourage this pollution.

What are the Major Effects of Thermal Pollution?

Thermal shock resulting in rise in temperature of water bodies – When industries and factories dispose the water, used as coolant, back into water bodies the temperature suddenly raises to an abnormal level. The sudden and abnormal temperature level acts as a thermal shock for aquatic life, which is adapted to living in a specific temperature and cannot, handle the abrupt change in water temperature.

Depleted level of oxygen in natural water – When warm water discharged by industries enters the natural water bodies, they get heated up. The warm water causes an unusual growth of plants and expansion of algae. The algae expansion in water reduces the level of oxygen in water.

Contamination of water – Thermal pollution also results in contamination of water because various chemicals and other wastes get mixed up with the water that is disposed off back to rivers, ponds, lakes, etc., by various factories. If this contamination of water keeps on increasing, humans can suffer from shortage of

When the water is accumulated at these spaces, it gets heated up and gets mixed with seas, ponds, lakes, etc., thus making way for thermal pollution. Hence, by making appropriate arrangements at such places, we can stop water from getting accumulated.

Co-generation – Co-generation is also a wonderful idea to combat thermal pollution. In the process of co-generation, the useless heat from hot water can be recycled and used smartly in many tasks by industries.

Cooling towers – Cooling towers is also a good idea when talking about the solutions for thermal pollution. The purpose of using cooling towers is the same as artificial lakes. The cooling towers also use the hot water of industries, process it by transferring its heat and transform hot water into cold water. This cool water can be recycles and used again for different industrial
