Barcelona’s tap water is safe to drink, but it has a persistent problem: it is one of the hardest in Spain, with typical values of between 250 and 350 mg\/l of calcium carbonate \u2014 well above the 200 mg\/l threshold the WHO considers soft water. You notice it in the taste, in the limescale on appliances and in the white residue on glasses and kitchenware. A reverse osmosis system installed under the sink eliminates between 95 and 99% of those salts, producing water with a lower dry residue than most bottled water \u2014 without bottles, without plastic and without a cost per litre.<\/p>\n
At JAG Alcaide we have been installing domestic reverse osmosis systems in Barcelona for decades. We work with Klinwass Montana 5-stage filtration units, fully installed with VAT included and 0% interest finance available. Before installation, we test your tap water quality in front of you with a conductivity meter so you can see exactly where you are starting from and what the result is after filtration.<\/p>\n<\/div>
What does installing a reverse osmosis system in Barcelona actually solve?<\/strong><\/p>\n Most clients who call us have one or more of these problems: the water tastes or smells of chlorine, leaves white marks on glasses and the coffee machine, or they simply don’t trust the tap water and have been buying bottled water for years. Reverse osmosis does not improve the water slightly \u2014 it transforms it completely. The conductivity meter moves from typical Barcelona values of 600\u2013900 \u00b5S\/cm to below 20 \u00b5S\/cm after filtration.<\/p>\n What it also resolves, and what many people don’t factor in, is the cost of bottled water. A family of 3\u20134 people buying bottled water spends an average of \u20ac20\u201340 per month. The unit pays for itself in under two years, and from that point on the cost per litre is practically zero.<\/p>\n<\/div><\/div><\/div><\/div><\/div> What is reverse osmosis?<\/strong> When the natural flow reverses, the water of the salt solution is forced to pass through the membrane in the opposite direction by applying pressure. Through this process we are able to produce pure water by removing the salt and other contaminants.<\/p>\n The reverse osmosis membrane has a pore size much smaller than the size of a bacterium or a parasite. When working properly it will remove all microorganisms from the water that goes through the pipe, producing sterile water.<\/p>\n Do you want to consume high quality water, even with lower dry residue than the bottled water?<\/strong><\/p>\n We recommend you to try our reverse osmosis system. We offer ourselves to visit the place where you are interested in getting the water tested. Once we get there we will check, in front of you, the level of quality that the water reaching your place has. We will use different testing systems including a dry residue measurer.<\/p>\n Are you aware of the impurities that can be found in the water you consume daily?<\/strong><\/p>\n Although the water that reaches our homes is supposed to be purified, everyday it is more contaminated by waste coming from domestic, agricultural and industrial sources. In addition it gets even more contaminated in the water distribution pipes that bring the water to our places, this is why generally, the more closer a house is to the sea the more contaminated the water is.<\/p>\n<\/div><\/div><\/div>
\nReverse Osmosis is a system that consists on reversing the natural flow of osmosis. In the water purification system, the goal is to dilute the salt solution while separating also pure water from salt and other contaminants.<\/p>\n![\"Reverse](\"https:\/\/www.jagalcaide.com\/wp-content\/uploads\/2022\/12\/osmosis_inversa_1.png\")
