Application of different models for management of drinking water quality

Access to safe drinking water imposes an obligation to preserve and protect it against pollution through the establishment of protection zones of the source. If pollution, despite of all the measures still occurs, it is necessary to introduce drinking water preparation techniques so that it meets all the prescribed health conditions. The paper presents conventional drinking water preparation methods along with the review of available models for simulating the drinking water quality. Moreover, these models are used for optimising drinking water production plants. A particular review was given for the Otter and Stimela environment models as a basis for developing new drinking water models within international projects. In this paper some positive examples of using individual processes from the Stimela environment are presented in the world and in our country.
