Description: According to the World Health Organization, human diseases caused by consumption of low-quality water can account for up to 80% of the total number of health problems. In general, more than half of the world population consume low-quality water, and thus every third inhabitant is endangered by gastrointestinal diseases. Economic damage from morbidity of the population using low-quality water virtually cannot be measured to the full extent due to specifics of the problem and incomplete initial data. Nevertheless, one can say with certainty that this component predominates in the total amount of damage from pollution of water sources. Sewage of enterprises contain oil products, heavy metal ions, and many different chemical compounds. Harmful chemical elements and substances enter water bodies worsening their sanitary condition, which requires thorough water treatment before using it for household and drinking purposes and for some industrial purposes.
