Everything you should know about water filter system
How does a reverse osmosis system for home
Reverse osmosis is a natural and simple water filtering system that retains the impurities present in the water to allow only the water molecules to pass. To achieve this result, hydraulic pressure is used to force water to circulate through a semi-permeable membrane. This then retains the particles previously contained in the water and which the pressure difference prevents from crossing.
The efficiency and speed of filtration depending on the material used for the reverse osmosis membrane. For an optimal result both in terms of efficiency and duration, a membrane made from composites of cellulose, polyamide, and polysulfone is most often used.
Reverse osmosis thus makes it possible to filter most of the particles present in tap water, to reduce its hardness, and to remove undesirable pollutants (sulfur, potassium, mercury, barium, zinc, iron, calcium, viruses and bacteria of all kinds, etc.). This process, therefore, makes it possible to obtain pure and drinkable water quickly and at a lower cost.
What type of filtration and water purification to choose?
Reverse osmosis or ultrafiltration?
Ultrafiltration is a water filtration system based on the method of membrane separation of water and particles. The water circulates through membranes which retain particles and residues according to their size and weight. This system therefore only retains a certain number of impurities. However, ultrafiltration makes it possible to obtain purer water and can be used for the production of drinking water, in addition to other purification systems.
Reverse osmosis or water softener?
The softener makes it possible to transform hard water, i.e. water with a high concentration of limestone, into softened water, also called soft. The softener thus protects the pipes against the formation of scale and limescale deposits and avoids the inconvenience of limescale on the skin and hair. Its process using an ion exchange resin targets the calcium and magnesium ions contained in the water and which are at the origin of the limestone and transforms them into sodium ions. The softener therefore only treats problems related to limestone and can act in addition to a reverse osmosis system (both to preserve the installation in place and to rid the drinking water of its limestone if necessary).
