There is a possibility that after some time the coal will nevertheless be “washed away” from microbiological contamination, but it is best to replace the cartridge with a new one immediately after prolonged non-use of the filter.
Another source of microbiological contamination of water may be storage tanks for its storage. In essence, the problem is similar to the previous one: with prolonged storage of water in a tank, even with a minimum initial number of microorganisms, they multiply, develop, and the storage tank becomes a constant source of infection of purified water. In the local water treatment scheme, these are most often tanks for the accumulation of water after reverse osmosis plants. And if the industrial Ro plant membrane is indeed an absolute barrier to all impurities of water, including microorganisms, then there is no absolute confidence in the sterility of the tank. Various microorganisms may be present in the tank initially or get into it already at the installation stage. To prevent or solve this problem, manufacturers recommend periodically treating the storage tanks with bactericidal preparations, for example, sodium hypochlorite solution. However, to fully guarantee their own safety, water after the tank is also better to disinfect.
What methods and methods of disinfecting water can be used in everyday life? Of the most common, the following are distinguished:
- boiling
- UV disinfection
- Ultrafiltration or industrial Ro plant
- the use of filter materials with bactericidal properties.
Boiling is one of the easiest, most affordable and quite effective ways to disinfect water. This method allows not only eliminating the majority of microorganisms, including pathogens, but also getting rid of the unpleasant odor of water caused, including by residual chlorine. At the same time, it is inconvenient to constantly boil drinking water, in addition, boiling has other disadvantages:
- residual chlorine present in water can form even more dangerous by-products when heated;
- some bacteria are quite resistant to thermal effects and die after a long time – up to several hours of continuous boiling.
- Thus, boiling can provide a high degree of disinfection of water, but for a complex and longer effect, it is desirable to use additional methods of disinfection.
