How to purify water yourself?
If you do not want to rely on the conscience and responsibility of bottled water producers, you will have to solve the problem on your own. There are several options. Jug-type water filters The advantages of this solution are portability, no need to connect to the water supply and low price. These qualities can be useful in a country house where there is no centralized water supply, or, for example, will be relevant for people who do not need daily filtration of significant volumes of water. It is easy to take a filter jug with you when moving: just select a replacement cartridge for the properties of water in a new place. A jug may be relevant in small offices. The main disadvantages of filter jugs are known to many: Low resource filter cartridge. The cartridge is intended to a greater extent for the purification of water, already rid of basic impurities. It is obviously not enough to filter unprepared water. Low filter performance - depending on the model, it ranges from 0.05 to 0.25 liters per minute but it is one of the best water filters for home. In other words, to get a liter of water, you will have to wait 4-20 minutes. And this is easy to explain: water passes through such a filter solely under the influence of its own weight. If you are going to buy a filter jug and knowing that you need to take into account performance, some will decide to choose a “faster” filter. But not so simple. As mentioned above, water flows through the filter to the bottom of the jug under the action of gravity, which means that only the presence of larger particles of activated carbon, which creates fewer obstacles to the passage of liquid, can accelerate the filtering process. Thus, we get a more efficient filter, but due to the loss of filtration quality, which leaves much to be desired. Larger particles - this is a smaller adsorption area with which water comes into contact, therefore, the degree of absorption of harmful substances in such filters will below. Sometimes manufacturers take a different path: they do not compress activated carbon particles inside the filter poorly. At least once having bought such a filter, it is impossible not to hear how the coal inside the cartridge is poured during its installation. Loose equipment of adsorbent particles allows water to pass through the filtration stage faster. But how is this going? Water gradually finds itself the shortest way through obstacles on the way, washing out the channels through which it follows with the greatest speed, as well as with the least cleaning efficiency. In addition, there is another drawback of filter jugs: they must be used daily. The downtime interval should not exceed eight hours, otherwise, the mechanism of bacterial propagation starts directly in the cassette, where a nutrient medium for microorganisms has already accumulated. You should also strictly monitor the timely replacement of cartridges according to the attached instructions, making an adjustment for the quality of the water that is poured into the filter. Otherwise, there comes a time when the filter gives off more harmful impurities and bacteria than it absorbs. filter jug from a reputable manufacturer and a supply of replaceable cartridges is a convenient solution for people who do not need a lot of drinking water.
