Treatment plants are facilities designed to process and purify water or wastewater. They play a crucial role in ensuring that water is safe for drinking, recreational use, and environmental discharge. The treatment process typically involves several stages, including screening, sedimentation, filtration, and disinfection, to remove contaminants and harmful substances. In addition to water treatment, there are also wastewater treatment plants that focus on treating sewage and industrial waste. These plants help protect public health and the environment by reducing pollutants before the treated water is released back into rivers or used for irrigation.
