Understanding Solar Salt for Water Softeners

Solar salt is a popular and cost-effective choice for water softener regeneration, produced through the natural evaporation of seawater or brine in large solar ponds. This environmentally friendly production method results in salt crystals that are typically 99.6% pure or higher, making them ideal for water softening applications. Solar salt is available in both crystal and pellet forms, with crystals being particularly effective for creating the brine solution needed to regenerate water softener resin beds.

Key Benefits of Solar Salt:

• Cost Efficiency: Generally more affordable than evaporated salt pellets while maintaining high quality
• High Purity: Natural evaporation process results in minimal insoluble matter and contaminants
• Fast Dissolving: Crystal structure allows for quick brine formation and efficient regeneration cycles
• Environmentally Friendly: Solar evaporation requires less energy than mechanical evaporation methods
• Reduced Bridging: Less prone to salt bridging in the brine tank compared to some pellet forms
• Wide Availability: Readily available at most home improvement stores and online retailers

How Solar Salt Works in Water Softeners:

Solar salt serves as the sodium chloride source for regenerating water softener resin beads. During the regeneration cycle, water dissolves the solar salt crystals in the brine tank to create a concentrated salt solution. This brine is then drawn into the mineral tank where it flows through the resin bed, displacing the accumulated hardness minerals (calcium and magnesium) and replacing them with sodium ions. The displaced minerals are then flushed out during the backwash cycle, restoring the softening capacity of the system.
