Useful Guide to Water Softener Sizes

Ion-Exchange Water Softeners SizesSalt-based ion-exchange water softeners are classed in sizes according to the capacity of the resin beads to remove ‘grains’ of water hardness. Each grain of water hardness is equal to 17.118ppm (or mg/L), and each cubic foot of standard 8% cross-link resin beads is generally rated at being able to remove 32,000 […]

The 4 Best Methods of Water Softening

soft water

Water softening in its strictest form implies the removal from the water of the minerals that cause water hardness, namely calcium and magnesium – and to a much lesser extent, iron. The most effective means of achieving this is by a process of ion-exchange, whereby the calcium and magnesium cations are removed and replaced by […]

How Do Water Softeners Work?

Lime Scale

There are a number of types of device that claim to soften hard water, including standard salt-based ion-exchange softeners, salt-less chelation-based water conditioners, and electromagnetic de-scalers. Salt-Based Ion-Exchange Water SoftenersSalt-based ion-exchange water softeners are the truest form of water softener; they remove hardness-causing calcium and magnesium ions from hard water to ‘soften’ it, replacing them […]
