Potabilization

Water for human consumption should be either physical-chemical as bacteriological safe.
- Physical: water should be transparent, without any turbidity nor colour or odour.
- Chemical: it should have the right dissolved salts content and an absence of harmful products.
- Bacteriological: the presence and growth of specific micro-organisms affecting human health should be controlled.

Therefore, drinking water treatments should be aimed at reaching these three levels, once achieved; water will be suitable for human consumption.
Natural water can be non-drinkable due to one, two or three of the levels mentioned, thus the target potabilization treatments should have is to work out the foresaid levels, preventing them to occur while in storage and /or distribution.
