Introduction

Water is a natural resource, without which human life is impossible. Until recently it was in abundance and its consumption was uncontrolled. However, nowadays everybody knows that a shortage of fresh water is a global problem.
The two factors the water crisis is caused by are the quantitative and qualitative factors. First means that there is not enough water to meet the needs of the population and industries. Second means that there is enough water, but its quality does not meet the requirements of water consumers.
The increase of water supply problems fell on the second half of the XX century. The main reason for water shortage consists in the growing disparity between the rapid growth of consumption and the invariable amount of fresh water. The rapid growth in water consumption is based on the unprecedented growth in the global economy and on the food crisis, which began in many countries. It can be argued that the relationship between the disposal of the water resources and growing demand has reached a critical point.
