Thermal pollution definition, a rise in the temperature of rivers or lakes that is injurious to water-dwelling life and is caused by the disposal of heated industrial waste water or water from the cooling towers of nuclear power plants. Thermal water pollution is the degradation of water quality due to a change in ambient water temperature. Thermal pollution, by the name itself, it implies it is warm or hot. While talking about pollution and by going into each types of pollution in detail, we may feel that there is no part of thing that is not polluted. Iceland is known as a strong leader in the movement toward sustainable, green energy. The warmed water may become a thermal pollution problem in terms of the receiving body of water. As a result, the coral organisms die, known as coral bleaching. But how it acts as a source of thermal pollution? These industries use water as a coolant and discharge it back at an elevated temperature (8-12 degrees higher) that affects the ecosystem. The level of water bodies rises due to consistent soil erosion and sedimentation, which makes it directly exposed to the sunlight. Power plants stationed along rivers employ two main types of cooling systems, namely once-through and recirculation (tower) cooling. Nuclear Power Plants Nuclear power plants use water as a cooling agent. Many plant and animal species survive in the aquatic ecosystem. explained as the addition of surplus heat to water and ejecting it back to the water bodies This is one of the most severe effects of thermal pollution. Their life is in danger due to the continuous increase in temperature. Deforestation also contributes to greenhouse effects causing global warming, which is again helping to thermal pollution. The warmed water may become a thermal pollution problem in terms of the receiving body of water. Installation of human-made structures like cooling ponds and cooling towers will help the areas where a tremendous amount of heat is released through various processes like evaporation convection, radiation, heat transfer, etc. That thought cannot be wrong as we come up with another kind of pollution, named thermal pollution. 18 total results. Top Answer. Well, to tackle this problem, first of all, you need to know its roots. High temperature can be a reason for the releases of immature eggs. Introduction Thermal Pollution is the harmful increase in water temperature in streams, rivers, lakes, or occasionally, coastal ocean waters. This process deals with the recycling of heated water for domestic purposes and industrial heating. Coal mining involves all kinds of risks for the miner; mine gas and silicosis are two examples. An article by Water Research Center shows that when the dissolved oxygen levels drop from 4-5 mg/l to 3 mg/l large population of fish can die or their reproduction rate drops drastically. Apart from air pollution, water pollution, environmental pollution etc. Thus, domestic & industrial effluents are one of the main sources of thermal pollution. On the other hand, those who fail to adjust often become endangered and eventually extinct. Required fields are marked *, What is Thermal Pollution? In simple terms, the warm water contains less oxygen as compared to cold water. g. Use of alternative cooling agent ( for example, fin fan coolers use air to cool). The production of energy from a fuel source can be direct, such as the burning of wood in a fireplace to create heat, or by the conversion of heat energy into mechanical energy by the use of a heat engine. 2. Some thermal power plants use coal as a fuel. Thermal pollution occurs when water bodies are degraded in terms of altering their temperatures. As a result, wind may blow the loose sediment to nearby bodies of water. An example of thermal pollution that is indirect could be agricultural practices like removing trees and topsoil which can cause soil erosion. [Cause, Effect & Control], Various industrial processes use water as coolant and discharge hot water into the natural resource that affects the. On the other hand, there are a few organisms which benefit from the thermal pollution. We also interact with several instances of thermal energy in our daily lives. The sudden loss of biodiversity leads to further issues with the aquatic ecosystem. Thermal pollution dramatically affects the biological activities underwater that may lead to significant biodiversity loss. This is also a big reason for thermal pollution. The release of excess heat to the atmosphere is the primary cause of thermal pollution. The local aquatic ecosystem can be damaged by thermal pollution, especially if it is dramatic, as in copious amounts of warm water being dumped into a chilly pond or bay or river. The consumption of coal in industrial activities leads to the following pollutants that increase the problem of thermal pollution- 1. Various industrial processes use water as coolant and discharge hot water into the natural resource that affects the ecosystem and nearby communities. without proper sewage treatment. But sometimes cold water can cause thermal pollution too. Thermal pollution is a significant threat to plants and animals living underwater. A threatened or endangered local population may be wiped … Some natural causes like geothermal activity & active volcanoes below oceans & seas also trigger the natural underground heating of the water bodies. ----- THERMAL POLLUTION ITS EFFECTS AND TREATMENT Presented to the Conference on Wastes Engineering - University of Minnesota Minneapolis, Minnesota January 9, 1970 Prepared by Robert W. Zeller, Ph.D Working Paper No. Specific ecological imbalances occur due to increased water temperature affecting the associated ecosystem. The underwater organisms have to face the adverse effects of the heat discharge into water bodies. Biodiversity is affected due to the movement or killing of marine organisms. The formation of thermally polluted zones causes coral reef bleaching, leading to thousands of coral reefs’ death. The reduction in oxygen level pushes the anaerobic conditions underwater, affecting the life of various plant & animal species. Soil erosion causes the top layer of soil to break and washed away into the natural water bodies. Pre-cooling of warm water is necessary to prevent thermal pollution before discharging into nearby water bodies. A Cooling tower removes the absorbed heat by the evaporation process and dissipates it into the atmosphere. What causes thermal pollution? Deforestation is harmful to the environment in all the aspects whether we talk about climate change, global warming, greenhouse effect, or thermal pollution. Deforestation also allows more light to reach bodies of water, enabling them to absorb more heat from the ambient environment. By removing the thermal pollution from the Aare River the water density generally increases. Iceland is known as a strong leader in the movement toward sustainable, green energy. These industries take water from the nearby natural water bodies and discharge it back to the natural system after usage. Increase in Toxicity Cause Thermal Pollution, 4. On the other hand, some other industries like paper, sugar, textile and pulp industries, etc. Almost every industry needs the energy to run its machines. This sample paper is done by Joseph, whose major is Psychology at Arizona State University. The water acting as coolant exchanges heat with the process fluid and, in turn, becomes hot, then thrown back into the water bodies. Those are some of the ecological effects due to thermal pollution. Soil erosion and deforestation also cause thermal pollution. A minimal increase in water temperature causes significant changes in the aquatic culture. Warm temperature can reduce the density and viscosity of water and increase the settling time of suspended particles affecting marine organisms’ food supplies. Nuclear power industries release water that is slightly radioactive into the natural system, causing an increase in toxicity. Carbon monoxide – Coal fired thermal power plants are one of the main contributors for emission of carbon monoxide, which is produced due to the combustion process when coal is burned. Water temperature influences the biological activity and growth of organisms that live in natural water bodies and a slight increase in temperature can cause difficulty in their survival. 6. Earth is a unique planet that provides various resources needed for our survival. Ultimately, this warmer temperature may hamper the food chain’s stability, creating an imbalance in species composition. Therefore, we should concern about the causes, effects, and control measures of thermal pollution. Examples of Thermal Pollution Around the World.
