Water means life

Water is one of the most important things in human life. We would like to make our students conscious of its great importance and aware of dangers caused by lack of water.

Water in products and technological processes

All products around us, have water in them in  certain sense. It is obvious that we can't live without the water. It is possible to live without food for a few weeks, but it is not possible to live without water for more than five days.

Water is a very good solvent and the environment for all vital processes. It is an essential element and a product of many biochemical reactions. Liquids and the food eaten by human are the main water source. Every day 1/3 of daily water supply is complemented by the food we eat. Almost all food products contain water, however fruit and vegetables contain the highest level of water.
