Retrieved 19 February Views Read Edit View history. The benefits of salt systems in pools are the convenience and the constant delivery of pure chlorine-based sanitizer. Salt water chlorination is a process that uses dissolved salt 2,—6, ppm as a store for the chlorination system. This requires the frequent addition of hydrochloric acid HCl, also known as muriatic acid to neutralise the alkalinity and convert the sodium hydroxide back into sodium chloride i. It is not necessary to use a chloride-based acid to balance the pH.

This could be represented roughly as follows with the ions all separated in solution.. Unsourced material may be challenged and removed. The reduction of irritating chloramines versus traditional chlorinating methods and the "softening" effect of electrolysis reducing dissolved alkali minerals in the water are also perceived as benefits. This extra step is not needed in a sodium chloride system, as chlorine is effective as both a sanitizer and an oxidizer. Usual levels are 20 — 50 ppm.

What is a salt water swimming pool

Swimming pools Water treatment Chlorine. Sulphate ions conduct electricity equally well as chloride at the electrode, but will not produce any chlorine. Upper Saddle River, NJ. Such systems reduce, but do not eliminate, the need to clean the electrolytic cell and the occurrence of calcium scale in the water. Certain designs of saline chlorinators use a "reverse-polarity" design that will regularly switch the roles of the two electrodes between anode and cathode, causing this calcium buildup to dissolve off the accumulating electrode.

Description: Thus, depending on water chemistry and magnitude of use, the cell will require periodic cleaning in a mild acid solution 1 part HCl to 15 parts pool water which will remove the buildup of calcium compound crystals, such as calcium carbonate or calcium nitrate. The benefits and downsides are the same as those of a salt system. Disadvantages are the initial cost of the system, maintenance, and the cost of replacement cells. This allows only the needed amount of chlorine to be generated based on the demand. Automation systems will also manage levels of sanitizer by monitoring the ORP or redox levels of the water. Use of another acid, such as sulphuric acid to neutralise pool alkalinity will reduce the pH but will produce sulphate ions rather than chloride ions. They also require the pH to be kept between 7.
