Generally, wastewater is polluted by chemicals and various microorganisms which are dangerous for human life. That is why there are several stages of water treatment: chemical, physical (purification with the help of the physical processes) and biological (neutralization of the harmful bacteria and viruses). The greater part of the wastewater is treated in the special wastewater treatment plants which purify water with the help of the methods mentioned above. The water is filtered, treated by chemicals and physical processes there are supplied to the consumers all the time. Unfortunately, only a certain percent of wastewater is treated somehow, because the greater part is simply poured into the rivers, lakes, or mixes with under water and as a result the image of global water pollution is terrible.
