If you are getting your water from a well on or near your property, you need to treat it very carefully so that it is safe to drink. If your water is coming from a municipal water supply, you should take a sample and have it tested. A professional analysis of your water might find that there are different types of minerals or chemicals dissolved in your water. At certain concentrations, many common materials can be harmful and need to be filtered out. The best way to know is to have the sample analysed, and then filter your water appropriately. There are some general ways water is treated, though.
Typically, a domestic water treatment system is a two-stage system: filtration and disinfection.
The first stage of a typical Barnstaple water treatment system is filtration. Water is filtered through a physical filtration mechanism. Activated charcoal is the most common filtering material since it has more surface area than almost any other substance. It is also non-reactive with water, so it won’t affect the water itself. It will just filter out the substances it bonds with. Furthermore, your system might have a specialised filtration unit.
After analysis, the professionals might find that your water has some suspended materials that are not readily removed by a charcoal filtration. They will then recommend specialised filtration units that are reactive with specific materials.
Once the water has been filtered of physical minerals, it needs to be disinfected. The most common disinfectant is actually UV rays. Ultraviolet light is dangerous in high doses since it is damaging to living organisms, which is why you apply sunscreen when you go outside. The same principle applies to viruses and bacteria. Relatively high doses of ultraviolet light tend to kill bacteria and viruses, rendering your water potable.
