What do softeners take out of the water?

Hard water has calcium and magnesium ions in it. Water softeners are made to get rid of these ions. The minerals that make water hard are calcium (Ca2+) and magnesium (Mg2+). The ion exchange process will also draw and eliminate any positively charged ions (also known as a cation). This can include things like iron and manganese as well as other minerals.


Water softening process What do water softeners do

When there isn’t much ferrous iron in the water, most of the iron is dissolved. Water softeners take it out. Iron makes water darker in colour and leaves stains on your toilet, bathtub, and sinks. Ferric iron, which doesn’t dissolve in water, is more challenging to get rid of with a softener. Ferric iron will build up on the resin bed and make it hard for the regeneration cycle’s backwashing to work. This can cause clumps of iron in your softened water and make the resin beads less effective. When dissolved iron comes into contact with oxygen, it changes into ferric iron. So, a water softener can remove dissolved iron, but if your water has a lot of iron, some of it will always turn into a form that can’t be dissolved. If your water softener is dealing with a lot of iron, you should clean your softener bed with a chemical solution like Rust Out to extend the life of your resin beads. The best way to get rid of iron from water is with an iron filter or a more complete filtration system like reverse osmosis.
