Solar Salt vs Salt Pellets…What’s the difference?

Pellets are a food-grade mined salt that is washed and compressed into pellets thus making them a purer, cleaner salt vs salt pellets - salt pellet image

Solar salt and salt pellets are commonly used in the ion exchange process in water conditioning equipment.  We are often asked what are the differences between solar salt and pellets.  Both products are different forms of sodium-chloride which is the same substance that is in the salt shaker on the kitchen table.  The difference has to do with how they are manufactured.

Solar Salt

Solar salt is created through the evaporation of naturally occurring brine, such as sea water.  Shallow, outdoor brine ponds are exposed to the sun and wind, leaving behind a layer of natural salt crystals.  Even though solar salt is 99.5% pure, it is not as clean as salt pellets.

Salt Pellets

Salt Pellets are a food-grade salt that is washed and compressed into pillow-shaped pellets thus making them a purer, cleaner product.  Salt pellets are typically 99.7% to 99.99% pure.  They leave little to no residue in the day tank.  Even though pelletized salt is food grade, the pellet press process does not meet food grade standards.  As a result, pellets are not recommended in food processing such as canning and meat packing.  However, we do carry a full line of food-grade salt.

Cope Salt offers superior quality solar salt and salt pellets.  Both are effective at regenerating a water softener.  Solar salt is slightly less pure than salt pellets but cost less.  It also requires more frequent cleanings of the day brine tank due to the sediment left behind.  Be sure to consul the equipment’s owner’s manual to determine if a certain type of salt is recommended for your system.
