Water treatment involves the removal of potentially harmful substances, be they biological, chemical, or physical, to ensure the safety and suitability of water for human and domestic use. This process aims to produce water that is not only safe but also clear, colorless, odorless, and palatable. By eliminating or reducing harmful substances, water treatment safeguards against the consumption of contaminated water sources that could lead to health issues. Consequently, it is crucial to establish water treatment facilities with adequate capacity to adhere to established standards and remove pollutants before supplying water to consumers. In this review, a comprehensive report on various water treatment methods is presented.
