It's no secret that in our time most of the diseases that people suffer are related to the use of poor-quality and uncleaned drinking water. After all, more than 85% of all metabolic processes of the body are carried out in an aquatic environment. And in order to ensure the compliance of tap water by the world standards installed, various cleansing systems are used.

To date, there is a huge selection of coal filters for water purification using a variety of work principles. According to the purification method, mechanical, ion exchange, reverse osmosis filters, biological, physico-chemical and electrical are distinguished. Each of them has its advantages and disadvantages.
The main advantages of coal filters
Consider coal filters for water, based on clarification, that is, such a cleaning method, the essence of which in the mechanical purification of water from different impurities that limit the ability to use it for drinking or other purposes.
Water coal filter used to delete :
- free chlorine;
- unpleasant liking;
- unnatural color of water;
- various organic substances in water up to the smallest suspended particles and even viruses;
- odor.
The basic principle of charcoal filters - this absorption - absorption of solid material (sorbent) molecular contaminants. The filter media used in the filter of activated carbon. It is made from coconut shells or specially treated stones, and thus it has a high abrasion resistance.
The advantages of charcoal filters include:
- lower costs for their operation;
- long service life;
- a wide range of temperatures treated water;
- do not require washing reagent;
- the material from which the filter is manufactured, has light weight and it reduces water flow to the drain.
Varieties of charcoal filters, their characteristics
Among the huge range of modern carbon filters, it is very difficult to choose something that is really suitable for the production of high quality and treated water. Consider the characteristics of different types of filters:
1. The easiest and probably the most common schitaetsyafiltr pitcher. Its main advantages are:
- ease of use;
- high mobility.
This filter does not need to be connected to the water supply, but just enough to pour the water and wait 5-10 minutes to clean it passed. It is suitable for office, to make tea or coffee, as well as its easy to take along, for example, in the forest or the sea. This filter has a cartridge which effectively purifies water by most microorganisms.
The disadvantages of this filter includes:
- slow water purification;
- small cartridge yield, 150-250 l;
- with continued use of the filter on its surface are beginning to breed bacteria, so the cartridge should be changed at least once a month.
2. Another type of filter is a charcoal filter attachment, it is placed directly on the crane and purifies the water flowing therethrough. It is the smallest and most compact filter, very easy to use. The advantages include:
- easy to mount;
- rate of water purification, but the quality suffers;
- it is economical as it allows to get a tasty and healthy water at a low price.
The main drawback is:
- rapid wear of the filter element. She's just like a filter jug \u200b\u200bis designed for small amounts of water and is therefore not suitable for permanent use.
3. Stationary filters are the most expensive. They are quite productive, have from 3 to 7 degrees of cleaning, do not need to be careful and extremely economical in terms of replacing consumables. On the other hand, water is obtained distilled. It does not have useful salts and trace elements for humans. Accordingly, the installation of this type of filters is very controversial.
Features of industrial filters
On accounts with household exist industrial coal filters for water. Designed for cleaning from smells, tastes, chlorine, etc.
Application areas of industrial filters:
- hotels, cottages;
- restaurants and cafes;
- water bottling equipment;
- purification of fresh and sea water;
- water purification at metallurgical factories;
- water purification on thermal power plants TPP;
- purifying river water;
- purification of water in the pulp and paper industry;
- water purification in metallurgy and other industries.
The advantages and advantages of these filters:
- high performance;
- different filtering degrees;
- economical energy consumption;
- easy to operate.
Boot coal filters can operate in duplex systems, triplex, cuadx, that is, two, three or even four filters work in parallel.
In industrial filters, activated coal of the best world manufacturers is used, which has a unique ability to remove the smallest microorganisms, large organic molecules, such as humic acids, petroleum products and chlororganic connections. This ability allocates industrial filters from non-industrial, based on the use of activated carbon based on coconut shell.
Since the production requires purification of water from organic substances, industrial filters are fully coping with the task, due to the fact that they are filled with activated carbon based on stone coal.
A wide range of presented cleaning systems allows filtering water from 0.5 to 100 m 3 in hour. All coal industrial filters are equipped with special valves that allow you to perform almost any functions.
What kind of carbon filter to choose
1. The market shows a variety of carbon filters for water purification. Let's start with the filter jug. The most popular trademarks are:
- Akvafor, Russia;
- Barrier, Russia;
- Geyser, Russia;
- Our water, Ukraine;
- Britt, Germany.
When choosing a filter of this type, an important factor is the material from which it is made, it must be high-quality plastic, which prevents the reproduction of various microorganisms on the surface and easy to operate and clean.
The volume of such filters is also important, it varies from two to six seven liters. The color gamut is the most diverse, they can be: blue, red, yellow, pink, gray, silver and other colors.
The type of resource indicator is mechanical and electronic. The price depends on the volume, firm, type indicator. On average, such filters cost from 8 to $ 50. Replaceable cartridges have a total cost from 3 to $ 8. The cartridge must be changed once a month. In principle, the quality of the jugs-filters in all trademarks equally high.
2. The filtering nozzle differs from the jug-filter in that it cleans the flow water that flows directly from the tap. At the same time, they are the most compact, take up little space and perform maximum work. These filters are of different types, for example, some winding on the crane, while others simply join with a tube with an adapter.
When choosing such a filter, pay attention to the strength and quality of the material from which it is made, since the device is constantly under pressure. It should also be taken into account the efficiency of this filter, which is indicated in its technical specifications.
Such filters have a very wide price spectrum from 8 to 80 $. They differ in design, functions, and quality of water purified.
3. Household coal filters for water, the prices of which are highest - is stationary type filters. They are mounted under the sink or in water distribution room. The service life is not limited, so the place must be thought out immediately.
Equipment transfer is a very complicated procedure. In addition, free access must be available to cleaner cartridges. Their replacement occurs once a year. Please note if you do not replace the filter on time, it will begin to give accumulated deposits, and water will become unsuitable for drinking.
The most popular type of stationary filters is a multistage filter. It consists of several filtering modules, which gradually purify water. Each of these modules performs its function:
- the first catches mechanical impurities;
- second disinfects;
- the third produces deep cleaning.
The filters themselves are made from both plastic and metal. When choosing a filter, pay attention to:
- number of degrees of clerk;
- operating pressure;
- features of the installation;
- work speed;
- the amount of processed fluid.
In order to optimally choose such a filter, it is necessary to give the water samples to the laboratory for the study, this will allow you to choose the optimal kit of cartridges. Price from 60 and to $ 500.
4. Industrial filters used to prepare water at various enterprises, including utilities, for further use . These filters allow you to get water that will meet the requirements of the enterprise on which it is established. The market contains such trademarks:
- Aqualine,
- Ecosoft,
- Jet
- Blue.
Filters differ in power, performance, speed. The choice of a specific model depends on the particular enterprise for which it is intended. These filters are the most expensive price of $ 1,000.
High-quality water is a source of health for the whole family. It normalizes the metabolism, moisturizes all the mucous membranes of the body, dies blood, makes the skin elastic and rejuvenates our body. Buy a carbon filter for water - this means taking care of the health of your whole family.
