Connection to an individual source does not exclude the absence of harmful impurities. The well water filter protects against lime and other contaminants. We will study the principle of choosing equipment, taking into account the budget, consumption volume and other important factors.
Harm of lime in water from a well for health and household appliances
Typical troubles are due to the presence of calcium and magnesium salts in the incoming liquid, which are formed during the dissolution of the carbonates of these substances. To find out which filter to put from lime, it is necessary to clarify the amount of funding. An appropriate budget should contain the initial investment, including installation work. It is also necessary to take into account the costs in the process of operation.
To determine with an acceptable level of costs, it is necessary to list the problems that the implementation of the corresponding project eliminates. The water coming from a typical well contains a lot of lime. The level of hardness in such springs significantly exceeds the current sanitary standard 7°F.
At this concentration of impurities, the following manifestations are observed:
- itching and irritation of the skin;
- eye redness;
- allergic reactions;
- deterioration in taste and turbidity of water;
- the formation of scale on the walls of dishes and heating elements of the equipment;
- plaque on washed linen;
- clogging of utilities.
Scale disrupts normal heat transfer and impairs the efficiency of heating equipment. To maintain the temperature set by the user in such conditions, you will have to spend more fuel and electricity. For this position alone, monthly expenses for a country house can increase by 20-30% or more in one winter season.
The above facts confirm the economic feasibility of increasing the budget. Even an expensive good lime water filter will pay off the costs that are expected in the presence of these problems. Removing impurities will help create conditions favorable to human health. The use of appropriate processing will prevent emergency situations, increase the resource of the connected equipment.
Main filters for water purification from lime and iron
Arrange for special preparation of all liquid coming from the source. This solution will eliminate the formation of plaque in pipes and locking devices, and ensure the normal functioning of other components of engineering systems. To solve this problem, you can use equipment that effectively performs water treatment at high speed.
1 place. hollow fiber
2nd place. Electromagnetic
hollow fiber
Mechanical cleaning can be performed with fineness from 0.01 µm using a special membrane. This level is referred to as ultrafiltration, which traps even bacteria. In fact, we are talking about the preparation of drinking water with the removal of all impurities hazardous to human health. Part of the dissolved mineral compounds passes through the barrier, which improves the taste and quality of the liquid for cooking. Simple models of this category (Aquaphor, New Water) are produced in the form of standard cartridges with a resource of 8-10 thousand km. liters.
More complex ones (Akvaris) can be washed, which allows increasing the volume of the treated liquid up to 450-500 thousand cubic meters. l. This manufacturer produces equipment with a capacity of 1 to 15 m3/hour, so any the buyer will easily find a suitable main filter for water from lime, taking into account individual needs.
Electromagnetic
The principle of operation of installations of this category is common to all products. An alternating electromagnetic field is formed by an induction coil in the working area with the help of a high-frequency signal applied to it. The main functional unit, the generator, is installed in a compact housing. The standard version provides light indication of modes, protection against voltage surges and automated tuning.
The actual electromagnetic apparatus is not a filter, since its operation does not trap any impurities. It changes the structure of salts and the distribution of charges on the surface of particles. This transformation blocks scale formation. The chemical composition is preserved. The effectiveness of the impact depends on the width of the frequency range and the power of the force field.
Technology advantages:
- fast installation;
- lack of influence on the pressure in the line, the quality parameters of drinking water;
- very long service life - more than 20 years;
- ease of maintenance.
For the right choice, you can study the information provided on the manufacturer's website.
Consider devices of two brands comparable in terms of basic characteristics in order to better understand the rules for a correct comparative assessment (Termite / AquaShield):
- minimum (maximum) generator power - 2 (10) / 5 (20);
- frequency - from 1 to 10/50 kHz;
- range according to the passport - not specified / up to 200 meters;
- permissible hardness in the source - not determined / up to 25°F.
The lack of basic data does not allow preparing a quality project. To calculate an effective scale protection system, the missing information must be obtained from the manufacturer.
Flow filters for water purification from lime in the well
The problem under consideration can be solved using standard cartridges. In this case, it is necessary to decide which filter housing is best placed in the supply line. Large specialized manufacturers offer customers the corresponding models in several versions.
The functionality of such cleaning systems is determined by the filling of the cartridge. Small colloidal impurities are removed by sorption materials based on activated carbon. Ions of salts and other substances are extracted from the treated liquid by synthetic granules according to the exchange scheme. Relatively large components (from 5 microns) are retained by foamed polymer inserts.
Aquaphor Viking
In thematic series, this manufacturer produces 2 models. The first - with a stainless steel case with a height of 255-595 mm. Compatible cartridges for it are manufactured with a resource of 15 to 100 thousand cycles. liters. When choosing the largest product, the passport capacity is 1500 l / h.
With the same allowable inlet pressure, analogues are produced (Viking Pro series), the body of which is made of reinforced plastic. The design of these models is improved by an air valve. Their main advantage is the ability to install large 20” cartridges. Such a solution does not increase productivity, but by increasing the volume of the working area, the resource reaches 150,000 liters.
Geyser Typhoon
If you buy a filter of this brand from lime for a well, you can use any cartridge from standard products of the 10/20 Big Blue or 10 Slim Line standard. The absence of restrictions on this item allows you to use products from other brands that perform the necessary functions at a relatively lower cost. However, it is not necessary to immediately reject branded interchangeable blocks. They are loaded with the patented Aragon material, which is capable of reproducing ion exchange and sorption processing along with mechanical cleaning.
The Typhoon series is made of stainless steel. The standard version provides for the installation of an air valve and an opening in the lower part of the bowl for draining precipitation. When installed with a branded cartridge 20 Big Blue, the system provides a performance of 45 ± 5 l / min. It is allowed to increase the pressure up to 8 atm. The replaceable block is fixed in the working position by means of a bracket connected to the clamping spring.
Water filters from lime under the sink in the apartment
For the preparation of potable water, the performance requirements can be reduced. But in this case, more stringent selection criteria apply to processing efficiency. Taking into account the noted features, an acceptable option is to increase the number of cartridges. Multi-stage technology allows you to select working units that are well suited to a specific composition of harmful impurities. Which filter to choose, you can find out after studying the typical models.

2nd place. new water
Barrier Expert
This series includes sets with three cartridges. For the treatment of water with a high (up to 5 ° W) salt content, the “Hardness x2” model is intended. The digital code in the name emphasizes double softening - pre-treatment and finish. The unit is capable of preparing up to 120 liters of purified water per hour. A characteristic advantage is a user-friendly proprietary scheme for replacing modules.
new water
This manufacturer increased the number of cartridges (4 pcs.), placed them in an aesthetic case and added a ceramic ball valve for clean water to the standard equipment. Brand flow filters are cleaned of lime, chlorine compounds, pesticides, and other contaminants at a rate of 60-120 l / h. The structural joints retain their integrity under repeated exposure to strong hydraulic shocks - up to 16 atm.
Which is better to buy and put in a private house and in the country?
At the first stage of project development, the content of impurities in the source is checked. It is not enough for a correct check to find out which filter is better for lime. In addition to salts in the results of laboratory analysis, you can see an excess of iron, hydrogen sulfide, and other contaminants. According to these data, suitable cleaning systems are selected.
To refine the search, information on the following items is added to the list of basic requirements for a filter in a private house from lime:
- volume and purpose of consumption;
- resource;
- start-up and operating costs.
The collected data will help to plan the budget with high accuracy.
Prices for filters against lime
For a comparative check, you can use the data on the cost of basic models as of the date of preparation of the review (data in rubles):
- body of the main water filter from lime Geyser Typhoon 10SL / Viking Mini - 8 880/ 8 900;
- electromagnetic device Termit T-35 / Aquashield Du 60 - 9 650 / 17 000;
- a system with a hollow fiber working block Aquaris - 43,500;
- set with several cartridges Barrier Expert / New water M420 - 5250 / 10820.
Additional costs may arise at the stage of connecting a water filter from lime. To avoid unexpected budget increases, you should prepare a project with an economic calculation of the costs of preparatory work, configuration and maintenance.
Our recommendations and conclusions
For a correct conclusion, it is necessary to make a comprehensive assessment of the advantages and disadvantages, to clarify the costs of long-term use of equipment. You can choose a relatively inexpensive flow-through water filter with standard replaceable lime cartridges. However, it will be more economical to use a flushable module. If there are no harmful impurities, the scale will be eliminated by electromagnetic treatment. Various combinations of functional blocks are allowed for a more efficient solution of individual tasks.
