Water filtration systems are actively developed and improved in many ways. As a result, the user receives more productive and functional cleaning agents, which also provide a high degree of water treatment. One of the main directions of development of such devices is the filtering element itself. New cleaning methods are also being promoted, which offer fundamentally different technological approaches to solving the problem of dirty water treatment. However, despite the emergence of new systems, the usual reverse osmosis unit with a traditional filtering scheme remains in demand. However, in order to increase the effectiveness of such equipment, many manufacturers are actively experimenting with their designs and functional content.
Reverse osmosis unit
The device is a multi-stage water treatment system, the work of which is to provide filtration on the principle of reverse osmosis. The cleaning function begins with pre-filtering. At this stage, particularly heavy, large and dangerous elements are eliminated, including mechanical particles, heavy metal inclusions, petroleum products with pesticides and other contaminants. Moreover, the effectiveness of this process depends on the cartridge filters of the pre-treatment system, as well as their quantity.
Then the main filtering units begin their work. Reverse osmosis membranes in the central unit realize finer cleaning, eliminating bacteria and viruses, inorganic and organic substances from water. The principle of operation of this unit is based on mixing clean and dirty water, after which the liquid is subjected to passage through the aforementioned membrane. The composition of such devices without fail contains a storage tank. It is in it that the membrane is located, due to which the water level is also controlled .
What parameters should be considered in the choice?
The main working indicator of a filtration system is the cleaning speed. It is influenced by many factors - from the characteristics of the membrane to the temperature of the served water. For example, household entry-level systems are able to clean about 40-50 ml per minute. Medium-sized units are already operating at a speed of 100 ml, and the most productive ones provide about 200 ml. The number of cleaning levels that a particular reverse osmosis plant implements without additional filtration components is also taken into account. Standard systems are equipped with 4-6 elements that form the central unit of water treatment.
Additional functionality
Until recently, pre-treatment systems were considered an indicator of the unit's premium quality and were supplied as optional equipment. However, today such solutions are provided for in the basic versions of even budget models, which cannot be said about additional stages of cleaning. For example, manufacturers include specialized filtration barriers at different stages of water preparation that work purposefully to rid the liquid of unwanted elements. This eliminates certain bacteria and salts.
A modern reverse osmosis plant is capable of not only cleaning, but also changing the characteristics of water in a special way. The premium models in some versions, for example, carry out its softening, eliminate scale, and also perform the conditioning function. It is important to note that the implementation of such tasks is not without the use of special filters. At an intermediate level, for example, activated pressed carbon from coconut particles is often used.
Reviews about the models "Aquaphor"
One of the most famous domestic manufacturers of filtration systems for water. The products of this brand are of high quality cleaning, and it is not only about the composition, but also about the taste. Many users indicate a pleasant taste characteristics of the liquid. Also, Aquaphor models are traditionally famous for their original design, allowing them to organically fit the design of installations into the kitchen. As for the disadvantages, the reverse osmosis installation of this manufacturer spends a large amount of water in the so-called drainage. In the process of filtering 150 liters, for example, about 600 liters can take up such a flow.
Geyser Model Reviews
We can say that these products are in direct competition with the aforementioned manufacturer. The owners of such plants also emphasize the high quality of cleaning, the ability to work with large water supplies and multi-factor filtration from a wide range of polluting elements. But there are also weak points that this reverse osmosis filter may disappoint. The installation is supplied with not the highest quality components and construction details. Users themselves point to the fragility of the cranes, errors in the wiring diagrams and, in general, the complexity of the implementation of installation actions.
Prio Model Reviews
In every sense, balanced in terms of characteristics, but an expensive filtration system, which not every ordinary homeowner can afford. Nevertheless, even demanding users indicate that the models of this company justify their purchase. This applies to the primary properties of cleaning, and ergonomics, as well as the external design. Suffice it to say that Prio reverse osmosis water treatment plants are provided with an easy-to-use housing and durable mechanisms for updating consumables.
Price issue
The simplest models that implement a basic level of purification with a minimum amount of water are available on the market for 4-5 thousand rubles. More technological models equipped with high-performance carbon membranes, in particular, can be estimated at 10 thousand. Further, the technical and structural performance of the apparatus, including the use of manufacturing materials, will also affect the cost. If a reverse osmosis plant is required, then you need to count on an amount in the range of 50-70 thousand. These are premium high-tech complexes that realize the purification of almost all known types of pollution of running water. A complete set of such a system may include several pressure boosting pumps, branded plastic eyeliners with a ceramic tap and, in some cases, automatic control of the filtration process.
Conclusion
The principle of water purification through reverse osmosis as such has opened up many filtration possibilities. But do not forget that multi-stage cleaning can also have negative aspects. For example, along with pollution, it is able to exclude useful elements from the composition. In this respect, a flow reverse osmosis unit with a minimized set of fine membranes is not so dangerous. In addition, such models are also characterized by a high filtration rate, which makes it possible to obtain a large amount of water resource at the output in a short period of time. However, the use of specific membranes with a focus on pollution of a certain kind today allows you to control the purification area, while maintaining a list of beneficial salts and microorganisms.
