Selecting the technology of water treatment in the present-day economic environment

Summary

A formal approach to the evaluation of water treatment technologies that provides for comparing quality parameters, costs, reliability and availability indices is suggested. It is shown that one and the same technology being preferable at one settlement, however, is unpractical for applying somewhere else. It depends on the local economic environment, water quality, reliability requirements etc. It is possible to select the best technology for any settlement basing on local conditions. For design people the formal approach to the evaluation of the selected technology can be simplified, particularly for the cost–quality or quality–reliability ratios.

Key words
