There are more ways for cleaning the water. Which of these should we use in order to effectively purify the water for drinking purposes? To give the correct answer to this question, it is necessary in each case to know from what you will clean the water. Here are the most common methods of water purification. It should be noted that in most cases the filter water purification is implemented more than in one way, but a combination of these. Such a comprehensive approach gives the best results. You can look for liquid filtration products and combine them.
Mechanical filtration – it is easiest way to clean the water. Mechanical cleaning of the water is provided by the capture of particles of insoluble substances from the difference in sizes of the particles themselves and the channels filter. Simply put, the water passes through a kind of “sieve”. The size of the particles retained by the filter is determined by the diameter of channels in the material of water purifier.
Mechanical filtration is widely used in municipal water treatment stations. This type of treatment is particularly relevant when taking water from open sources: rivers, lakes and reservoirs.
Ion exchange – it is a specific case of sorption of charged particles (ions), when the absorption of one ion is accompanied by the release in solution of another one, which is part of the sorbent. To understand it easier, you should imagine there is a substitution of some harmful ions, to the other harmless.
One of the applications of ion exchangers is water softening, when hard water is cleaned by excess content of calcium and magnesium ions.
Reverse Osmosis – a water purification using reverse osmosis membrane. Water with this method of treatment is passed through a membrane (like a sieve), the pores which pass water, but do not let the impurities dissolved in it. Reverse osmosis system produces water of very high purity. It can remove even monovalent ions such as sodium ions and chlorine. However such installations are very expensive.
Distillation – it is a less common type of water treatment. In the distillation system, the water is first evaporated and then condensed. It is the process of purification, comprising a liquid evaporation and condensation of steam. Distilled water is relatively clean, but the distillation process is quite expensive. Distillation systems must also necessarily contain activated charcoal, since there is no way to remove the low molecular such as chloroform.
