The only solution for treating hard water is installing a water softener in your house. There are different types of water softeners out there and choosing the best one for your hard water is not easy, but if you read this article from beginning to the end, you will be able to find the right system.
The different types of water softeners for hard water
Salt-free water softener
As the name suggests, salt-free water softener does not require salt well known as sodium to soften your hard water. What this softener does they do not remove hardness in your hard water but condition it, so that does not form build-up around your house appliance.
The salt-free water softener retains all hard minerals in the water but alters the chemical structure making them harmless through a technology called Template Assisted Crystallization (TAC). The Template Assisted Crystallization system needs no electricity, brine tank, salt, backwash waste, wastewater (since no regeneration cycle), control valve or electronic control system.
The system requires no maintenance because you don’t require buying and adding salt regularly you only need to replace the medium and some brands like Pelican Water Salt-Free Water Softener NS3 Natursoft has lifetime media.
Life expectancy of the salt-free medium can be lifetime no needs to replace while other brands have specific life expectancy depending on the product. When buying check the life expectancy
The salt-free water softener uses specialized treatment medium consisting of polymeric beads that are contained in a mineral tank when hard water is passed through the medium rearrange the water hardness structure such that do not form build up on the house appliances.
The TAC technology is an excellent alternative to conventional water softener which was first introduced 15 years ago in Germany, seven years ago in the USA and Canada and is gaining popularity worldwide.
Salt-based water softener
The salt-based water softener is well known conventional water softener that has been there for a quite while.
It uses salt to remove all minerals in the hard water.
This type of water softener has two tanks brine tank and resin tank.
The resin tank has resin beads and salt which are negatively charged. The hard water first passes through the resin tank, the hardness ions present in water which are positively charged are attracted on the negatively charged resin beads giving sodium ions through a process called ion exchange or cation exchange.
Minerals that were present in the hard water will remain on resin bead and treated water goes through your faucet for human consumption.
After some time the resin beads become coated with minerals present in your hard water. The mineral coat causes the resin beads not to operate effectively which needs to be cleaned.
The brine tank filled with sodium solution runs automatically or manually to the resin. It picks ions in resin beads cleaning the beads to operate effectively. The hard minerals are washed off from resin beads and flushed out the resin tank through the drain pipe. This process of cleaning resin beads is known as regeneration.
The water conditioners use magnets and electrical devices to send waves and pulses. The device is placed around water supply pipes to alter the molecular structure of the water’s hardness.
The conditioner does not remove minerals that cause your hard water to become hard but paralyze it for 48 hours, so it will not cause build up in your house appliance.
Both salt-free water softener and conditioner are best for people with a restricted diet.
How do you know which type to use
Test your water hardness you can use test kit at home, call or email your municipal if you use piped water.
If your water hardness is between 12-15 grains per gallon purchase a salt based water softener less than that you can use a salt-free water softener.
If you only want to protect your appliances from scale and matters build up you can consider buying a water conditioner.
