1. Purpose of the station

By this project we offer a mobile water purification plant for drinking water to be built.

The plant will be constructed in several modules, each one meant for different types of contamination.

Such kind of installations would be especially useful in some rural regions without electricity supplying net - small villages, camps and in cases of natural disasters as well.

The installation is meant to produce drinking water from any kind of contaminated natural source of water.

2. Drinking water productivity

The installation is meant to provide up to 1000 litres per hour.

3. Contamination of natural water sources

Very often natural sources of water are not suitable for drinking because of different kinds of bacteria, viruses, bad taste, smell, colour, turbidity etc.

  6. Contaminated source of water

In order to purify any natural water and to make it suitable for drinking according to the European standards we design four purification modules.

Each module is meant to purify water from different contaminations.

If the inlet water does not need some treatment according to the chemical analysis it passes by that module.

Let suppose our inlet water contains A, B, C and D types of impurities. In that case in order to purify it the water should be treated through every module.

If water is not to be treated for some specific contamination it passes by that module.

Finally the quality of the outlet water is to be checked by a chemical analysis.
