Abstract
In the article, a new method of continuous monitoring of the biological quality of raw and treated waters at the Želivka Water Treatment Plant is suggested and assessed. This water treatment plant is one of the largest water treatment plants in Europe and the largest water treatment plant in the Czech Republic with a maximum projected peak output of 7 m3.s−1 and current output of around 3 m3.s−1 of drinking water. It is the largest water treatment plant for Prague which is the capital city of the Czech Republic. Additionally, this water treatment plant also supplies drinking water to the Central Bohemia and Vysočina regions. The main intention of the research was to suggest a new system of monitoring, which can guarantee a more reliable continuous control of the safe drinking water supply for the city of Prague and the surrounding area. The suggested method represents a completely new approach to monitoring the biological quality of drinking water in the Czech Republic using the DaphTox apparatus, only two of which exist in the Czech Republic. The article describes the experience and knowledge gained during the operation of such a monitoring system, including a description of the necessary measures to ensure its proper operation with a focus on the pre-treatment of raw and chlorinated waters. Recommended simple pre-treatment methods secure optimal living conditions for monitoring organisms and have no impact on the original biological quality of monitored water which is a necessary condition for proper monitoring of biological quality.
Highlights
“Clean water—a healthy city” is a generally valid statement and the name of the project, which was solved within the framework of the Operational Programme Prague—Growth Pole of the Czech Republic
The following text describes the experience and results gained in the concept which dealt with the improvement of the early warning system at the Želivka Water Treatment Plant
No cases of a significant reduction in the biological quality of the monitored waters were detected in the course of this test operation
Summary
“Clean water—a healthy city” is a generally valid statement and the name of the project, which was solved within the framework of the Operational Programme Prague—Growth Pole of the Czech Republic. This programme was financed by the European Structural Funds and the European Regional Development Fund. Support of the introduction of new environmentally favourable technologies and practices Due to the complexity of several interrelated issues, e.g. contamination of drinking water reservoir and river sediments, a survey of sources of pollution in the river basin, the use of activated carbon sorbents for water treatment, improvement of early warning system at the water treatment plant and presence of selected pollutants in Prague wastewaters, the project consisted of four relatively independent parts called concepts. The quality of water in this reservoir is endangered in the long-term period mainly by eutrophication, pesticide pollution and erosion (Liška et al, 2016; Mičaník et al, 2020)
