THERMAL POLLUTION
Thermal pollution comes from the heating of natural waters by introducing hot water used in cooling power plants, nuclear plants, refineries, mills and various industries.
It is known that fish need oxygen (O2) dissolved in water to survive. The amount of O2 is affected by warm water, since the solubility of a gas in a liquid decreases as the temperature increases. Therefore, a water out of the natural patterns of temperature is considered polluted, unfit to all life.
Dead fish are often found on the slopes of thermally polluted rivers. What do about this disaster? The solution to the problem would be to change the procedures used by the industry. Alternatively, you could store the heated water eliminated during the process until it was at lower temperatures, only to then throw it into rivers.
Another problem the problem is the junction of water polluted by chemical waste with hot water, then we both like the thermal water pollution. Surely there is no life in this medium, and that is how every day our rivers have been increasingly attacked by man.
