What is a water filter?

Filters improve water quality and are widely used not only in water treatment plants to supply water to factories, but also if you have your own merits. It is more and more common to install water filters in apartments and private homes to improve the water parameters and quality standards provided by municipal waterworks.

To make the right choice for our tap water filter, you need to specify the requirements and expectations of the water used.

 

Tap water is tested periodically and the results of the water analysis can be applied to the relevant water supply company or local sanitary and epidemiological department.

 

If water is taken from your own well, such water quality testing can be done at a field sanitary and epidemiological station.

Domestic water filters should be certified indirect contact with drinking water NIH.

 

Just behind the water meter, in every household water installation, t is possible to install an inline filter mechanical mesh - the led tank will trap large solid objects such as sand or rust. Thanks to this, our bathroom and kitchen faucets as well as all appliances connected to the water system will be protected from damage. Such a filter should have the capacity to adapt to the flow of water.

 

Filtering technology

Numerous filtering technologies are used in the design of water filters.

 

Mechanical filtering

Mechanical filtration, where gravity passes water through a filter cartridge in which large-diameter impurities (sand, fiber) accumulate

 

The carbon method

- Carbon method, where cartridges made of activated carbon are used, which have more emotional properties. This results in improved water taste and odor, and elimination of chlorine, organic matter, and phenols.

 

Iron removal filtration

- Iron removal filtration process during water uses the process of iron oxidation, thus removing iron and manganese compounds from the water

 

Softening water

- Artificial ion exchange beds with the participation of salt soften water during the exchange of calcium and magnesium ions with sodium ions.

 

Irradiation of water

- Water irradiation from ultraviolet light removes bacteria and viruses

 

Reverse osmosis

- Reverse osmosis, i.e. filtering under pressure through a semicircular membrane through which only water molecules pass. In this way, mechanical and chemical contaminants, bacteria, and viruses are removed.

 

Types of water filters

In households, water softeners, carbon, and reverse osmosis filters are often used.

 

Tap the water filter

The most sought after filter in the kitchen is a tap water filter. If filtered water is only to be used for food preparation, but only a pitcher filter. However, its performance is limited, so if you have a large budget, it is worth getting a faucet or closet filter.

 

Reverse osmosis water filter

The under-closet water purification system will be more professional and a system with a reverse osmosis water filter will meet the expectations of the most demanding people.

 

Mechanical filter for water

Mechanical water filters prevent solid particles, suspended solids, rust, lime fragments, and other appliances installed in the home water system from these impurities.

 

String filter for water

A string water filter is a mechanical filter that is made of cotton or polypropylene wire. Made of polypropylene non-woven fabric and pleasing, foam is also used.

 

Iron and manganese filters

Iron and manganese filters remove iron and manganese compounds as well as nitrogen compounds from water.

 

Ceramic insert filters

Ceramic or special resin filters have a disinfectant effect.

 

Drinking water filter

A reverse osmosis filter for drinking water removes all minerals, salt ions, heavy metals, organic pollutants, and bacteria from the water.

Water softeners

Water softeners purify the water of calcium and magnesium compounds and soften the water on the skin and hair, and also make the detergent faster. However, this method does not guarantee the purification of water from inappropriate chemical and organic compounds. So let's install a carbon filter in the kitchen too.

 

Carbon filter for water

A carbon filter for water is often combined with a sediment filter, so mechanical, chemical, and microbiological contaminants are removed from the water, and the taste and smell of the water is improved. However, this filter requires periodic replacement of the cartridge.

 

Such filters contain activated carbon which absorbs large amounts of impurities. The carbon cartridge is impregnated with silver or other compounds with a bactericidal effect and inhibits the growth of bacteria on the cartridge, for example, copper and zinc compounds.

 

Reverse osmosis

Reverse osmosis purifies the water of harmful substances, but unfortunately, it also removes minerals, so minerals are also used to supplement the extracted and beneficial minerals in the water. However, the biggest disadvantage of this method is water consumption. To get 5 liters of clean water, it is necessary to filter 40, 90 to XNUMX liters of tap water, and a large amount of water passing through the filter leads to wastewater.

 

Semi-permeable membranes, carbon, and sedimentation are periodically changed.

 

Tap the water filter

A modern tap water filter uses multiple water purification technologies at the same time, so first the water is mechanically purified, passes through a sediment filter, then passes through a carbon filter. Is, and then goes into the asthmatic membrane.

 

Water filters are also aided by UV lamps.

 

Water filters - construction and assembly

Water filters are different from the way they are made and where they are installed:

-Nakranvi

 

Installed (standing)

 

- Under the closet

Berta pitcher water filter

Berta pitcher water filter is an easy solution. The jug is equipped with a carbon filter and allows you to improve the taste and smell of the water and remove chlorine and mechanical impurities from it, although this water may contain bacteria. Frequent filter cartridge replacement is required.

 

Duffy water filter

The Defy Water Filter is a functional kitchen appliance equipped with indicators that remind you to change cartridges.

 

Faucet filter

A faucet filter is a carbon filter attached to a faucet. Filters water under network pressure. It improves the taste and quality of water, cleans it from chlorine, chemicals, and mechanical impurities. It has a moderate price and is easy to install. Carbon cartridges need to be replaced from time to time.

 

Our cabinet (standing) filters are mounted on the surface of the sink next to the cabinet. They are very easy to install and use sediment and coal technology. They purify water from chlorine, chemicals, and mechanical impurities. They need to change the cartridges from time to time.

 

Water filter under the sink

Underneath the sink is a water filter (under closet, under the sink). It is connected to a network and a separate tap. The filter for drinking water under the sink acts as a reverse osmosis principle or filter of carbon and sediment and, importantly, is hidden because the whole installation is hidden in the cabinet.

 

It has a much lower efficiency than filters that treat all household water, but filtered water is of very good quality and can only be drunk from a tap.

 

Shower filters

Shower/bathroom filters are mounted on faucets, carbon, and mechanical filters are hidden in the shower duct or in the cabinet under the sink.

 

Central filters

Central filters are often applied with hydro for in abundant soft homes or in single-family homes or service plants. Soft water is supplied to all appliances and taps, protecting the building's central heating and household appliances, as well as the skin and hair of household members.

 

Household water filter

The capacity of a domestic water filter that is installed to treat all the water used in the house by its own use should be quite high.

 

Pressure filter columns or filters with pressurized high-performance cartridges can be used here. When water contains iron, manganese, calcium, and magnesium ions as well as nitrogen compounds, insufficient pH, and heavy metals, the filtration system will definitely be useful.

 

Filter column

Filter columns are free to stand devices with a capacity of 1-3 m3 / hour for a family home. The pressure column is filled with a filter bed adapted to water pollution. Each filter bed works effectively as long as it is not saturated. , And after that, it will have to be recreated. The work of the column is controlled by the head which operates infiltration, cleaning, or regeneration mode. Can work in time mode or volume mode.

 

The treatment station should be located near the building's water connection (boiler room, utility room), behind the hydrophone, when the water comes from the water itself, or behind the water meter in the water supply system.
