How does twin tank water softener work

Hard water gets into the first resin tank that contains resin beads while the second resin tank is reserved. The resin beads are negatively charged and hard water is positively charged.

The negatively charged resin beads attract positively charged ions in the hard water through a process called ion exchange.

Minerals that make water hard remain on the resin beads and soft water pass through the resin tank ready for human use.

After some time, the resin beads are overcoated/saturated with hard water minerals. During this time the beads do not operate effectively they require to be cleaned to provide soft water.

The process of cleaning the resin beads is called regeneration.

During regeneration time the system switches to the second resin tank. The regeneration process takes place in the first resin tank.

 What happens with a dual tank ion exchange water softener when one tank is softening water the other one is regenerating as a result conditioned water is supplied throughout without downtime or break up.

When you are buying dual tank water softener make sure you have enough space where to install, it requires drain pipe for backwashing, and others require electricity to operate, ensure the power source is located nearby.
