Various effective technologies exist among the methods of natural water purification. Mechanical filtration can remove large particles in water. Using chemical substances like chlorine or ozone, microorganisms are eliminated. Additionally, coagulation and flocculation methods help clump small particles in water for easier removal. The sorption method involves organic and inorganic pollutants being removed with activated carbon or other sorbent materials. Lastly, membrane filtration, such as reverse osmosis, can purify water to a very high degree and even denazify it. These methods are crucial in preparing water resources for safe use
