Transforming the water from the reservoirs, for human consumption, complying with the requirements of current legislation, is the most important mission carried out in drinking water treatment stations.
Drinking water must not contain any type of microorganism, parasite or substance, in an amount or concentration that could pose a risk to human health, therefore, and in general, a drinking water treatment plant (DWTP) has to follow a sequence of operations:
1. Pretreatment: removal of large solids that may contain water.
2. Coagulation-flocculation: Adjust the pH of the water by the addition of acids.
