Solar Evaporation methods produce the purest salt of the many different commercial salt mining and producing methods. It will produce 99.5% pure salt – and this is the recommended purity level for salt water chlorine generation. When buying salt for your pool or hot tun chlorinator, always look for Solar Evaporation with above 99% purity!

Solar Evaporation is the oldest method of salt production and still is the most environmentally friendly. It has been used since salt crystals were first noticed in trapped pools of sea water. Solar salt production is filling shallow ponds with saltwater where the sun evaporates most of the water. The salt is then gathered by mechanical harvesting machines. Any impurities that may be present are drained off and discarded prior to harvesting.

These salt ponds range from to 40 to 200 acres with a foot-thick floor of salt resulting from years of depositions. During operation salt water flows continuously through these ponds. This is called a saturated brine solution, containing as much salt as it can hold, so pure salt crystallizes out of the solution as the water evaporates. Natural chemical impurities are returned to the salt water source.

Chlorine Generators are changing how Americans, Canadians and Europeans are managing their hot tubs and spas.  The technology was first implemented in Australia years back, but has now come to this side of the world.

Salt water Chlorine Generators are the natural way to keep your hot tub or spa water sparkling clear, fragrant  and fresh.  Spa owners are turning to this natural way to keep their tub clean and healthy,  rather than continually dumping harmful chemicals into the water.

How a salt water chlorinator works

The first component is, of course, salt. Instead of the hash chemicals, you put a small amount of salt in the water - less than the salinity of your tears. The salt, dissolved completely in the water, is made up of sodium and chlorine.

The chlorine generator contains a series of plates with opposing electrical charges.  These charges start a very small chemical reaction called electrolysis which releases chlorine from the salt.  This is the most pure form of chlorine and since it is already in the flowing water, there is never any residue or by-products.

Note: Saltwater from the ocean has approx 20,000ppm (parts per million) of salt. Saltwater chlorinators require around 3000ppm, which generally can’t even be tasted.
