Benefits Of Installing A Zodiac Salt Water Chlorination System
Installing a salt water chlorinator is a great choice for a new pool or for retrofitting an existing system. Traditionally, chlorine levels were maintained by testing the water manually then directly adding chlorine to the pool in liquid, granular or tablet form. Salt water chlorination systems from manufacturers like Zodiac is a far superior choice and much easier to maintain. But many prospective buyers ask, "How does salt water chlorination work?" Here's the answer.
A salt water chlorination system works by a process that uses dissolved salt in the pool water to generate chlorine through electrolysis. The chemical reaction produces HCIO (hypochlorous acid) and NaClO (sodium hypochlorite) which disinfects and sanitizes the water. Saltwater swimming pools are not in fact "chlorine free" but simply generate their own chlorine through the electrolysis system.
The advantage of a salt water chlorination system are numerous. First, the system is self-regulated, meaning the equipment constantly tests the water and levels are increased or decreased as required. This assures the pool stays at its optimal chlorination level and stays clear, clean and resists algae build-up. Some systems will also test and regulate pH levels.
The other significant advantage is the elimination of skin and eye irritation found in traditionally chlorinated pools. This is because the electrolysis process burns off chloramines which is responsible for the irritation, as well as the unpleasant chlorine smell. This makes for a much more enjoyable experience for both swimmers and those lounging around the pool area. The system is also great for those with respiratory problems that can be aggravated by the chlorine odor.
A few other benefits. The bleaching effect on hair and clothes is eliminated (and no more green tinge for blond haired swimmers). Plus the salt iodine in the water benefits sun tanning! And that bad taste and smell that clings to your skin is gone. While your pool will be "saltwater" it is no where near as salty as the ocean (seawater is about 35,000 ppm dissolved salts vs. About 5,000 ppm for a pool).
From a technology standpoint, salt water chlorination a system of titanium plates coated with transition metal from the platinum group (such as iridium or ruthenium). The electrolysis and resulting chemical reaction with the water's dissolved salts is what produces the hypochlorous acid and sodium hypochlorite which work to sanitize the pool. To maintain the proper water salinity, pool salt is simply poured into the pool's shallow end and brushed gently until the majority of it is dissolved.
The pool's chemical balance must still be tested on occasion to ensure proper chemical balance so the chlorine is being utilized effectively. Testing the water's cyanuric acid level is important because it helps to stop UV rays from destroying the chlorine. The pH level of the water is also important to maintain. Like low levels of cyanuric acid, a low pH level (high acidity) makes the chlorine less effective.
So if you'd like to worry less about your pool's chemicals and focus more on enjoying the water, you might explore adding a Zodiac salt water chlorination system. The upfront cost is more than made up for by the long-term savings. The self-regulating system makes it worry free and you'll get a fresher, less caustic swimming experience.
