What Is Saltwater Filtration?

Most swimming pools utilize a chemical disinfectant system to remove biological contaminants and other undesirable growth. In these systems, chlorine is made actively available to combat contaminants and render them into harmless byproducts. Most traditional filtration systems require the addition of chlorine directly to the pool water.

Saltwater filtration also uses chlorine for removing biological matter, but the means of providing the chlorine are remarkably different. Instead of adding chlorine manually, saltwater systems generate the necessary chlorine via a process known as electrolysis.

Manufacturing chlorine involves a chemical reaction between dissolved salt (sodium chloride) in the water and a submerged metal catalyst. As electricity passes into the catalyst, it generates a steady stream of chlorine molecules by breaking apart the salt.

In the same way that chlorine is manually deposited into a pool and performs organic material breakdown, chlorine generated by electrolysis also attaches itself to debris and biological matter.


Advantages of Saltwater Filtration

Saltwater filtration offers advantages that make it worth considering when installing a new pool. First of all, the chlorine produced by a saltwater filtration system is pure and helps lessen the probability of chloramine buildup. Chloramines are the strong-smelling agents that occur as a result of chlorine deterioration and can cause eye irritation for swimmers.

In addition, saltwater systems often prove to be more comfortable for swimmers. The saltwater creates a soothing, relaxing buoyancy that is easy on the skin and other sensitive tissues.
