The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. As solid material decays, it uses up oxygen, which is needed by the plants and animals living in the water.
Heat energy would be the fuel for a hurricane. Also the warmer the water is, there is more moisture in the air, which can lead to even larger and stronger hurricanes
