Reverse osmosis water treatment plant

Water filtration systems are actively developing and improving 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 filtration element itself. New cleaning methods are also being promoted, which offer fundamentally different technological approaches to solving the problem of treating dirty water. However, despite the appearance of new systems, the conventional reverse osmosis unit with the traditional filtration scheme remains in demand. However, in order to increase the efficiency of such equipment, many manufacturers are actively experimenting with their designs and functional content.

Reverse osmosis device

The device is a multi-stage water treatment system, whose work consists in providing filtration on the principle of reverse osmosis. The cleaning function starts with the pre-filtering. At this stage, especially heavy, large and dangerous elements are eliminated, including mechanical particles, heavy metal inclusions, petroleum products with pesticides and other contaminants. In this case, the efficiency of this process depends on the filter cartridges of the pre-treatment system, as well as their number.

Further, the main filtering plants begin their work. The osmotic membranes in the central block realize a more subtle cleaning, delivering water from bacteria with viruses, inorganic and organic substances. The principle of operation of this unit is based on the mixing of clean and dirty water, after which the liquid is subjected to a passage through the membrane mentioned above. Without fail, the composition of such apparatuses contains a storage tank. This is where the membrane is located, which also controls the water level.

What parameters to consider in the selection?

The main working indicator of the filtration system is the cleaning speed. It affects a lot of factors - from the characteristics of the membrane to the temperature of the treated water. For example, entry-level home systems can clean up about 40-50 ml per minute. Medium-sized units operate at a speed of 100 ml, and the most productive units provide about 200 ml. Also, the number of purification levels that a particular reverse osmosis system implements without additional filtration components is taken into account. Standard systems are equipped with 4-6 elements, which form the central unit of water treatment.

Additional Functionality

Pre-cleaning systems until recently were considered an indicator of the premium installation and were supplied as an optional equipment. However, today such solutions are envisaged in the base versions of even budget models, which can not be said about additional cleaning steps. For example, manufacturers include specialized filtration barriers in different stages of water preparation, which work purposefully to remove liquid from unwanted elements. Thus, certain bacteria and salts are eliminated.

A modern reverse osmosis plant is capable not only of cleaning, but also of changing the characteristics of water in a special way. Premium models in some versions, for example, mitigate it, remove 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. On an average level, for example, activated pressed coal from coconut particles is often used.

Reviews about models «Aquaphor»

One of the most famous domestic manufacturers of filtration systems for water. The products of this brand are characterized by high quality of cleaning, and it is not only about the composition, but also about the taste. Many users point out the pleasant taste characteristics of the liquid. Also, the models of "Aquaphor" are traditionally famous for their original design execution, allowing organically fit the designs of installations into the kitchen environment. As for the disadvantages, the reverse osmosis unit of this manufacturer uses a large amount of water in so-called drainage. In the process of filtering 150 liters, for example, this flow can take about 600 liters.

Reviews about models «Geyser»

You can say that this product is a direct competition to the above-named manufacturer. Owners of such installations also emphasize the high quality of cleaning, the ability to work with large water reserves and multifactor filtration from a wide range of pollutants. But there are also weak points, which can be disappointed by this reverse-osmosis filter. The installation is not equipped with the highest quality components and design details. The users themselves point out the flabbiness of the cranes, the errors in the connection schemes and, in general, the complexity of implementing the assembly activities.

Reviews of Prio models

In every sense, a balanced by performance, but expensive filtering system, which not every ordinary landlord can afford. Nevertheless, even demanding users testify that the models of this company justify their acquisition. This applies to the primary properties of cleaning, and ergonomics, as well as the external design of the structure. Suffice it to say that the reverse osmosis Prio water treatment plants are provided with an easy-to-handle casing and robust renewal mechanisms for consumables.

Price issue

The simplest models that realize a basic level of purification with a minimum volume of water are available on the market for 4-5 thousand rubles. More technologically advanced models equipped with high-efficiency carbon membranes in particular can be estimated at 10,000. Further on the cost will be affected by the technical and structural design of the apparatus, including the use of manufacturing materials. If a reverse-osmosis plant is required, it is necessary to calculate the amount in the range of 50-70 thousand. These are premium high-tech complexes that realize cleaning from practically all known types of pollution of running water. The system may include several pressure boosting pumps, branded plastic connections with a ceramic tap and, in some cases, automatic control of the filtration process.

Conclusion

The principle of water purification by means of reverse osmosis as such has opened many filtration possibilities. But do not forget that multi-stage cleaning can have negative aspects. For example, together with contaminants, it is able to exclude useful elements from the composition. In this respect, a flow-through reverse osmosis plant with a minimized set of fine cleaning membranes is not so dangerous. In addition, such models are also characterized by a high filtration rate, which allows obtaining a large volume of water resource at the outlet in a short period of time. However, the use of specific membranes with a focus on the pollution of a certain kind today allows you to control the purification area, preserving the list of useful salts and microorganisms.
