ADVANTAGES OF ELECTROCHLORINATION:

Electrochlorination is the only 100% safe chlorine technology as Cl2, in the form of a low concentrated hypo solution, is generated:

on-site (at the point of application)
on demand (only when required and always "fresh")
no bulk storage (because it is generated on demand)
only basic/safe inputs are used (seawater + electricity, or, fresh water + salt + electricity)

When using an electrochlorinator, there is no need for any commercial chlorine products. It is a safe, economical and independent chlorine alternative to hazardous, high concentrated commercial chlorine products e.g. gaseous chlorine, commercial hypo and dry chlorine (granular calcium hypochlorite)

It is also safe for the environment:

no heavy metal pollution (e.g. copper or lead), and,
chlorine decomposes back into common salt (sodium chloride) again
