Filtration devices for water have many varieties that differ in design, cleaning efficiency and other parameters. One of the most popular systems is the backbone. It represents a wide group of devices integrated directly into the water supply circuit. Most often, main filters for household cold water are used, but similar systems are also used in industry. The cleaning capabilities of such equipment allow it to be installed even in medical institutions, where increased demands are made on water quality.
Features of the design of main filters
The design device is due to the nature of the operation of the equipment. The filter is a modular device that is built into the water supply. Thus, a technological cleaning unit is organized, from which the fittings for connecting pipes depart. Typical trunk-type water treatment equipment includes a pressure reducing valve and a flushed filter element for fine filtration. In the process, water bypasses the filter barrier, heading for the outlet fitting. The cleaning material is flushed with a ball valve - contaminants are removed through it.
Filter options may vary, but threaded fittings, valves, and a pressure gauge to monitor pressure readings are usually included in the base. The main filters for cold water practically do not affect the operation of the circulating system as such. In modern versions of equipment, manufacturers seek to minimize the coefficient of water retention during the passage of filtration material, which makes it possible to balance the supply and output forces.
Equipment advantages
From the point of view of domestic operation, the main water treatment facilities are convenient for use. When using pitcher filters, manual organization of the process is required, and the system integrated into the water supply channel does not require user intervention in the work process. As for efficiency and quality, the main purification of drinking water fully complies with the requirements of sanitary standards. Multivariate water treatment is being implemented, eliminating liquid, including chlorine and rust. The elimination of impurities is also important as a way to preserve water circuits, which are negatively affected by direct contact with mechanical particles. In terms of service, such systems do not deliver any particular problems either. It is enough to change the filter material as it wears out. Depending on the type of this material, the working resource varies from 15 to 60 thousand liters.
Types of devices
As already noted, filters of this type can be intended for domestic and industrial use. So, household filters are distinguished by finer cleaning, small size and less high working life. Industrial models focus on ridding water of large impurities - this applies to models that prepare industrial water. For sanitary needs, where the same clean drinking water is required, a fine filtration step is also provided.
The main treatment devices are also divided according to the number of modules, that is, the very stages of treatment. The main share of the segment is represented by models with 1-3 modules. An industrial filter that implements coarse cleaning for the use of liquid for work purposes may have a single module. It will save water from rust, sand, metal suspensions, etc. Household filters designed for household tasks can be supplied with one cleaning module. Such a filter can be installed directly on the supply line of a washing machine or dishwasher. Multistage cleaning is realized by two- and three-module devices, which, in addition to eliminating heavy impurities, also rid the water of toxins, harmful organics and even unpleasant odors.
Manufacturers
The filtration equipment segment in Russia is rather narrow, but the choice is huge. The most famous companies are “Aquaphor” and “Geyser”, which produce filters of different levels and types. In particular, Geyser offers a modification of the Typhoon 20BB designed for the fine preparation of drinking water. A direct competitor of this device is the Aquafor Viking main filter, which provides cleaning at a speed of 25 l / min. The features of this model include compact sizes with the ability to install in a remote place. There are interesting offers in the Honeywell family. The FK06-1 / 2 model is quite suitable for domestic household tasks, if you want to rid the stream of mechanical impurities, suspensions and rust.
How to choose main filters for cold water?
First of all, the approximate volume of water that will be used at peak loads is determined. An example of an Akvafor filter with a cleaning rate of 25 l / min can be called an average. To serve household needs in the apartment, 10-15 l / min is enough. High-performance equipment for water purification under production conditions can provide 50 l / min. Further, it will not be amiss to evaluate the temperature limits in which the filter can be operated. Models designed to serve cold flows are generally approved at 35–40 ° C. For comparison: hot water systems are supplemented by devices that support operability at a temperature of about 95 ° C.
Do not forget about the working pressure. The cleaning mechanism must cope with the loads in a particular water supply. Standard water treatment in the apartment can be performed at a peak inlet pressure of 6-7 atm. In industry, devices withstanding up to 25-30 atm are involved.
How to choose filter cartridges?
Like pitcher filters, the main cleaning devices do not work without special cartridges. Actually, the throughput and the quality of water treatment largely depend on them. It is advisable to choose cartridges from the assortment of the manufacturer that issued the filter itself. For example, Geyser recommends using consumables of its own Aragon series. The company "Aquaphor" is famous for its own cartridges no less than filter housings. If it is planned to purify drinking water, the cartridge must support fine filtering with the elimination of all harmful impurities. If this is unnecessary, and the filter focuses on rough cleaning, then the cartridges must be of the appropriate type.
Conclusion
The main water treatment systems are much more expensive than manual filters. The same models from the Geyser and Aquaphor firms are estimated at 10-11 thousand rubles. But it is important to understand that these costs pay off. Firstly, the main filters for cold water last longer, requiring less frequent replacement of the active cleaning element. Secondly, the use of filters built into the water supply saves the user time, saving him from unnecessary operations. And this is not to mention saving space in the same kitchen - the filter is hidden from view and does not become an obstacle in everyday life.
