Description

Washed solar salt is a type of salt produced by evaporating brine using sunshine. It is often made from seawater and may also be referred to as Solar Sea Salt. The manufacturing process involves pumping water into underground salt deposits to dissolve the salt, then pumping the brine into large outdoor ponds where it is exposed to sunlight to evaporate the water, leaving behind salt crystals[1].

Key Features

  • Higher purity: Washed solar salt is more soluble than other types of salt and can be found in up to 99.5% pure form.
  • Fewer impurities: The evaporation process removes many salt impurities, making it a purer product than rock salt.
  • Unique pellet form: The salt has been washed and compressed into pillow-shaped pellets, making it a convenient and easy-to-use form for water softeners[1].

Comparison to Other Types of Salt

Washed solar salt is distinct from rock salt, which is mined from underground salt mines and may contain significant amounts of calcium sulfate[1].
