Abstract

The methods and systems disclosed here relate to treating water using a hybrid softener system. In certain embodiments, a method of treating water comprises passing a portion of a water stream to be treated through an electrochemical water treatment device to produce a first treated water stream and passing a first portion of the first treated water stream through an ion exchange device to produce a second treated water stream. In certain embodiments, the hybrid softener system produces water of less than 1 gpg in hardness. The methods and systems disclosed here also relate to a portable version of the hybrid softener.
