For water drawn from wells, leave it for compounds to settle before you filter out clean water for use. With the exception of calcium, boiling does not remove solutes of higher boiling point than water and in fact increases their concentration due to some water being lost as vapour. Fluoride is usually added after the disinfection process. Boiled water should be covered and left to cool before drinking. The microparticles evaporate and condense, resulting in pure water.

First, the water passes through a 20 micrometre interference or filter to remove sand and dust particles, then a using to remove organics and and, finally, a to remove metallic ions. These filters contain special materials like charcoal, carbon, ceramic, sand, and cloth that are specially designed to filter out dangerous pollutants. In general, sedimentation basin efficiency is not a function of detention time or depth of the basin. In terms of viruses, hepatitis A is the main risk from contaminated water. In most developed countries, public water supplies are required to maintain a residual disinfecting agent throughout the distribution system, in which water may remain for days before reaching the consumer. This is removed from the sedimentation tanks at Zuikerbosch and Vereeniging in thin slurry containing 3% mass by volume of dry sludge. Reverse osmosis is the best option, whereas filtering is good for basic water tasks such as sediment and chlorine removal.
