Ceramic filter for Russian-made water: expert reviews

It's no secret that tap water contains a large number of additives, impurities, chemical elements and organic compounds. That is why people are increasingly resorting to additional filtering devices. There are many drinking water purification systems operating on different principles, but a ceramic water filter deserves special attention. Let's find out what it is and what is its fundamental difference from other types of filtering systems.

Ceramic filter device

The principle of operation of the ceramic filter is based on the passage of water through microscopic pores that do not pass and retain the smallest particles, contaminants and bacteria. Such porous structures are made of powder of silicon carbide, titanium dioxide, aluminum oxide by sintering at a temperature of 1600 degrees.

Such filters can be divided into two types:

• devices with a ceramic cartridge;
• ceramic membrane systems.

Ceramic cartridge

The liquid filter cartridge has millions of microscopic pores that can trap particles as small as 0.5 microns in size that settle and accumulate on the surface. Smaller particles of contaminants that could pass through the porous surface fall inside the cartridge. Its inner part is a complex labyrinth that traps the remaining impurities.

Ceramic cartridges are used in storage filter systems - dispensers, often in combination with activated carbon. The output is pure water, 98% free from all possible impurities.

Ceramic membrane filter

This type of filter is flow-through; its modification, suitable for use in an apartment, is usually washing device.

Passing through the membrane, the purified stream of water is divided into two streams: concentrate and filtrate, where all contaminants and harmful impurities are separated from pure water. Since water molecules are much smaller than impurity molecules, all water pollution cannot pass through the pores of the membrane, and the purified liquid flows freely.

Membrane-type ceramic filters consist of two components:

• a membrane unit containing a multichannel cermet tube, the inner part of which is a finely porous membrane;
• stainless steel cases.

There are three varieties of ceramic membrane filters:

1. Microfilters. The membrane of such a system is capable of retaining particles with a size of 0.1 microns, including some types of microorganisms and mechanical impurities.
2. Ultrafine cleaning devices. The size of the holes in such a ceramic membrane does not exceed 0.01 microns and does not allow the passage of heavy metal molecules, organic substances, many viruses.
3. Nanofilters. Purification is carried out at the molecular level, after which the water becomes distilled.

In addition to purifying water from pathogens, metals, organic compounds and turbidity, ceramic filtering devices can eliminate unpleasant odors and bites of water.

Unlike other types of filter systems

Nowadays, the consumer is provided with a very wide selection of drinking water treatment systems:

• reverse osmosis filters;
• cartridge;
• ozone;
• ceramic.

Let's compare the effect of a ceramic filter with other types of devices.

• The reverse osmosis system perfectly copes with the task of purifying water and removes everything harmful to it from it Unfortunately, the organism does not miss substances that are also useful, practically turning it into a distillate. The device of a ceramic filter allows you to retain harmful impurities, while not depriving the water of healthy salts and minerals.
• Fine cartridge systems, like ceramic ones, they purify water qualitatively, but unlike the latter, they require regular replacement of expensive cartridges.
• When choosing an ozone filter, you need to be especially careful, since undecomposed ozone is dangerous to human health. In addition, the ozone filter only disinfects water, destroying all types of microorganisms, without cleaning it from impurities.

In contrast to the above installations, ceramic filters have much more advantages than disadvantages. They have only one drawback - a rather high cost.

The advantages of ceramic filters

Ceramic filters for water purification have many indisputable advantages:

• Absolute safety. Removing impurities without the use of reagents eliminates the possibility of unwanted substances entering the water.
• Immunity to alkaline and acid influences, resistance to mechanical damage.
• Lack of consumables and replacement parts. The membranes of such filters are easy to clean using backwash, there is no need to change them due to clogging. Due to this, their service life is over 10 years.
• Due to the simplicity of the design, it is quite possible to install or replace such a filter without resorting to the help of specialists.
• Unlike the reverse osmosis filter system, the ceramic membrane does not deprive water of the potassium and magnesium ions necessary for the human body, eliminating only hardness salts.
• Quality deferrization of water.
• In the process of membrane contamination, the cleaning quality remains at the same level, only the throughput decreases.

Some models of ceramic filters provide additional use of activated carbon tablets, which further improves the quality of the water used for drinking and cooking.

Ceramic filters made in Russia

Several types of ceramic filtering systems are produced in Russia, representing unique patented developments.

• The “Akvakon” filter manufactured by the Binacor-HT company is intended for the purification of tap water from salts, rust, metals, chlorine and microorganisms, improving its taste, eliminating extraneous smells. The device has a self-cleaning function, is installed under the sink with water supply through a separate tap. Price - from 16 000 rubles.

• The KMF-0.15 system from NTC-Water purifies water from bacteria, solids, iron and heavy metals. Its features are resistance to high pressure, the possibility of self-cleaning, the absence of replaceable parts. The manufacturer offers two modifications of the device - for installation under the sinkat and a portable version powered by a network or a car cigarette lighter. Price - from 18 900 rubles.

From the beginning of time, to this day, water has been an integral part of our life. Water is 80% of the human body, so the quality of drinking water is of great importance. Very often people, not sparing money, buy expensive means of protection against viruses in tablets, drops and injections, without even suspecting that many diseases can be avoided with a conventional ceramic filter for water. Thinking about how much such a filter costs, you first need to ask yourself: how much is health?
