COSTS AND THE CHOICE OF DRINKING WATER TREATMENT
Disinfection types for drinking water systems with population less than 3000 for 2004 • The figure above shows at least one type of disinfection used by treatment plants which serve less than 3000 people • It is clear that the dominant disinfection type is chlorination. Chlorine is used in 127 of 136 systems (i.e., 93.38%) •
Pure chlorine is very toxic, even small amounts can be deadly. During World War I chlorine gas was used on a large scale to hurt or kill enemy soldiers. The Germans were the first to use chlorine gas against their enemies. Chlorine is much denser than air, causing it to form a toxic fume above the soil.

Water types. If the water is already of an acceptable quality, it will not usually be necessary to subject it to any treatment. However, in the case of hard water, saline waters, water with high concentrations of nitrates, iron or manganese, for example, a specific treatment should be designed to correct the necessary parameter and ensure the water is suitable for a specific use.
