Morton® Potassium Chloride Pellets are 99% sodium free! They add potassium to your softened water and reduce your water's sodium levels

These pellets provide the essential plant nutrient potassium to the ecosystem. Reduced sodium levels reduces chlorides discharged into the environment as well.

Morton® Potassium Chloride Pellets come in a convenient, easy-open 40-lb. bag.

Performance Data

We have received numerous requests from dealers and customers about the use of potassium chloride (s/b KCl) as a regenerant for water softeners. As a result, we set up two identical water softeners and regenerated one with sodium chloride and one with potassium chloride. Both units were exhausted with 13-gpg hard water. From the capacity data we obtained, it appears that potassium chloride can be substituted directly for sodium chloride in a water softener with no loss of capacity.

Experiments conducted in homes indicate consumers noticed no difference in taste between sodium or potassium regenerated softeners. There was also no noticeable change in the feel of the water softened by either regenerant.

The potassium chloride was supplied to us in a granulated form and the sodium chloride was furnished as pellets. Caking experiments showed granular potassium chloride was much more prone to caking and salt bridging than was sodium chloride. We also found that the solubility of potassium chloride fluctuates with temperature whereas the solubility of sodium chloride does not. In areas of the country where outside installations subject the brine tank to wide fluctuations in temperature the use of potassium chloride could result in brine draw fouling.
