Answer:

When there is bacteria in tap water, it must be treated before using it, especially for consumption. Certain bacteria in drinking water can cause a variety of severe diseases such as diarrhea, so it is important to remove bacteria from water before it is consumed.

Boiling Water to Kill Bacteria

Boiling the water will kill the bacteria but the dead remains are still in the water. The same goes for ozonation. Ozonation consists of infusing water with ozone produced by subjecting oxygen molecules from the air with high electrical charges. Chemical disinfection does not get rid of dead bacteria remains and you are left with the harmful side-effects and bad taste of chlorine.

In times of emergency, the Red Cross, FEMA (Federal Emergency Management Agency), and the AWWA (American Water Works Association) all recommend boiling water to kill bacteria, chemical disinfection, or preferably distillation. ” While the two methods described above will kill most microorganisms in water, distillation will remove microorganisms that resist these methods, as well as heavy metals, salts, and most other chemicals”.

Carbon Water Filters May Trap Bacteria

Carbon filters trap the bacteria and then feed them for rapid reproduction. Reverse Osmosis, with its carbon pre-filters and plastic membranes, again promote bacterial growth and bio-films. Bacteria can even grow through plastic membrane in a process sometimes referred to as “membrane creep”.

Water Distillers Remove Bacteria

The best solution to a bacteria problem in tap water is distillation. Not only does the first step of distillation (boiling) kill virtually all bacteria but the bacteria-free steam, rises leaving the dead bacteria behind to be washed away. The clean steam then passes through a stainless steel condensing coil where it is transformed into bacteria-free distilled drinking water that is pure and safe to drink.
