Which process distillation or filtration is used to produce drinking water from river water?

Distillation is used to produce drinking water from river water. Distillation is a process of boiling water and condensing the steam to produce pure water. It is one of the most effective methods of water purification, as it removes almost all impurities, including bacteria, viruses, and minerals.

Filtration, on the other hand, is a process of removing particles from water by passing it through a filter. While filtration can remove some impurities, it is not as effective as distillation in removing all contaminants. Therefore, distillation is the preferred method for producing drinking water from river water.
