The quality of water treatment in many cities is not high enough. As a result, under-treated water flows into residential buildings. Worn communications increase its pollution. All this negatively affects health. You can solve the problem by installing a stationary filter.
Understanding the dangers of using contaminated water, many people purchase various water purification devices. Jug type filters and nozzles on the crane are very popular.
They are convenient and do not require work to tie into the water supply. But they also have tangible flaws. The main disadvantage is the small volume and low speed of water filtration. This leads to the need to collect purified water in containers and provide space for their storage.
Stationary water filters are much more convenient. They are built into the water supply, and purified water is supplied through a separate faucet that is led to the sink. The cleaning speed in such systems is sufficient for domestic use, which will allow you to quickly fill the kettle or pot with water. Filtration quality in stationary water treatment systems is higher than in compact filters.
Multistage filters
This is the most popular type of stationary filter. Such devices consist of several filter modules. Each block performs its function. Most often, such systems consist of three cartridges. The first serves to capture the mechanical impurities contained in the water. This is rust, sand, scale. In the second module, water is disinfected and deeply cleaned. The cartridges of some manufacturers use silver ions, which destroy the dangerous microflora. The third module usually contains sorbents. The most popular substance is activated carbon. In this stage, the absorption of undesirable chemical compounds occurs.
The average cartridge life is a few months of the year. After this period, the modules must be replaced. If this is not done, the filter may begin to give up accumulated deposits, and the water will become unfit for drinking.
Flasks containing filter elements can be made of both plastic and metal. Plastic filters are cheaper, but can not withstand high pressure and collapse, which can lead to flooding of the apartment. When choosing a stationary filter made of plastic, pay attention to the quality of the material. Check the performance of the filter and make sure that it is able to withstand a sufficiently high pressure.
To achieve the best result, it is worthwhile to select filter elements, depending on the parameters of the water flowing through your pipes. Take water samples from your water supply to a specialized laboratory. This will allow you to identify the main pollutants and choose the optimal set of cartridges.
In addition to passive filters that trap harmful substances, there are active systems. In them, water is exposed to ultraviolet radiation or saturated with ozone. Such filters require an electrical connection and are more expensive than passive systems. But active filters provide higher quality cleaning.
