A huge amount of chemicals is a serious threat to drinking water. The good news is that concentrations of almost all these contaminants can be reduced by using existing water treatment technologies. On the other hand, the most complete removal will probably require a combination of several technologies, rather than one.
The results of scientific work on searching for new approaches to microorganisms show that the use of biological purification technology is promising. Unfortunately, the majority of municipal water supply and purification facilities experience a significant lack of funds, and financing of new technologies is, as a rule, expensive and therefore unavailable.
Activated carbon, long used for removal of chlorine, some gases and many dissolved organic substances, as it turned out, is an effective technology for adsorption of a number of low molecular weight pollutants. Ultimately, coal needs to be replaced, but waste coal can usually be buried safely. The family of membrane technology, microfiltration, ultrafiltration, nanofiltration and reverse osmosis is very effective in reducing a wide range of contaminants. These membrane technologies are most effective in treating water for drinking and cooking. Of course, they do not destroy the pollutants, but simply direct them to the sewer system.Distillation is also an effective technology to reduce water soluble contaminants. This process involves boiling water and then condensing water vapor to produce purified water. A potential problem is that organic substances with boiling points close to water temperature can also evaporate and enter the distillate. To solve this problem, you can additionally use activated carbon. A disadvantage of distillation is the need for a large amount of energy needed to boil the water and cool the distillate.
