Wastewater treatment and circulation in thermal power plants

Wastewater from thermal power plants comes from cooling and energy production processes. In thermal power plants, water is used to cool the plants and turbines, a process in which it heats up. After the water has been used for cooling or other processes, it becomes “wastewater” and must be managed properly to prevent pollution and protect the environment. Treating wastewater from thermal power plants is essential to prevent environmental pollution and to comply with environmental regulations. There are several technologies that can be used to treat wastewater from these plants, and their choice depends on the type and level of contamination of the wastewater. This paper analyzes how water is treated and used in a thermal power plant, each method having advantages and limitations, and the choice of technology depends on the type and concentration of contaminants, costs and regulatory requirements of each plant. Often, thermal power plants use an integrated treatment system, which combines several of these technologies to ensure process efficiency and protect the environment.
