Charcoal filter is currently the most popular water purifier. This is because it is extremely effective. It is also important that such filters are completely environmentally friendly. With their help, you can get water suitable for use in everyday life and food.
How it works?
The carbon filter is designed to purify water. It is used to remove harmful suspensions from it, as well as substances due to which the liquid may acquire an odor and / or color that is not characteristic of it. The main element in the design of the device is a special
activated carbon. It has a large internal surface. With this, coal begins to actively sorb unwanted impurities. In the process of absorption, its nanoporous structure also plays a role.
Now let's talk about the effectiveness of carbon filters as such. It will be enough just to mention the fact that the area of 1 gram of sorbent can reach 1500 square meters. By this indicator, the carbon filter is significantly superior to existing analogues.
Stationary appliances are usually fully automated. This ensures reliable operation of the devices. In addition, it allows you to control the regeneration process (restoration of the cleaning ability of the filter after processing a certain amount of liquid).
What filters are available?
First of all, different types of these devices are distinguished depending on their power and the conditions in which they are used. In particular, it is customary to distinguish household (for use at home) and stationary (for use in industry) filters.
Activated carbon of various types can be used as an active element in devices:
- stone;
- from coconut shell;
- anthracite;
- bituminous;
- woody, etc.
After some time, the download goes through a backwash procedure. This is necessary so that the coal does not cake in the filter. The download itself can be used several times longer.
Advantages and disadvantages of using carbon filters
First, consider the benefits that any carbon filter has. Among them, first of all, it should be noted:
- the possibility of obtaining water of the highest quality, purified from any harmful impurities;
- low cost of equipment and ease of installation;
- the ability to exclude additional devices from the water treatment complex;
- lack of need to wash loading acid solutions;
- compactness.
Carbon filters for water purification have disadvantages. But only a limited capacity can be attributed to them. Over time, they require replacing the cartridge, otherwise, after a certain period of time, the carbon filter will not begin to purify the water, but rather throw those harmful substances and compounds that were previously accumulated into it. However, if the cartridge is replaced at the intervals specified in the instructions, you can not worry about it at all.
Activated carbon filters are a simple, profitable and effective way to purify water in the home and industry!
