How to choose a water filtration system?

To improve the quality of the water, coming from a rainwater collector, a distribution network or a well, there is a solution: filtration. Anti-scale filter, sediment, magnetic, activated carbon or filter cartridge: it is possible to filter domestic water in many ways.

Why install a water filtration system?

Before going into detail, it is essential to understand that the installation of a water filtration system does not change the fact that the water is declared as drinking or not. The filtration we intend to speak acts on parameters that are not representative to determine whether or not water can be consumed.

Let’s take a look at the different configurations in which a water filtration system can be installed.

Filtration of drinking water

If the water comes from the public distribution network , from your well or from an extraction system , it may be necessary to correct some parameters to improve its quality . Whether for your consumption or to preserve your appliances or the heating system . The most common method is to use the filtration system to eliminate (or at least limit) scale and limescale . All suspended substances can thus be trapped on condition that the correct filter is used.

Rainwater filtration 

Rainwater from a water recovery system or a basin can be pumped to feed a high pressure flushing or hydro-cleaning machine . In both cases, the water must be purified from all the suspended solid materials it contains. This is why a water filtration system is perfect.

The recovery of rainwater is becoming more widespread due to the increase in water prices. If you collect rainwater for sanitary use (flushing, washing, irrigation), the installation of a best water purifier system is essential to preserve the plant and the equipment.

What are the different types of water filters?

There are many types of filters, but we focus on the most widespread and most used depending on the function required.

Filter cartridges 

Conventional filtration without a true active ingredient, in other words purely mechanical . The filter cartridge filters retain the suspended particles and are suitable for reducing the turbidity of the water (the fact that it is cloudy).

The filtration capacity is adjustable according to the size of the particles to be retained by suitably choosing the filtering diameter of the cartridges . This diameter varies from 5 to 100 μm (microns).
Cartridge filters are therefore suitable for multiple uses, such as retaining sand that could be in a rainwater collector or at the entrance of the home network to filter the micro-particles sometimes contained in the water. They are often washable , but it is necessary to periodically replace the filter cartridge filters. The most resistant are the coil filters.

Polyphosphate filters

Filtration that integrates an active compound to limit or eliminate any limestone . Very useful to prevent the incrustation of the pipes and the sanitary system as a whole.

The filters polyphosphates can be installed at the entrance of the pipe coming from the network (after the counter) or before the equipment to be protected (for example, at the entrance of a water heater ).
The polyphosphates act chemical ion the different limestone components, preventing their formation. Depending on the water consumption and the filter capacity, the active compound needs to be reloaded 1 or 2 times a year.
Polyphosphates filters can be made in the form of filter cartridge filters.
