Understanding Pool Chlorine
What is chlorine?
In whatever form, when chlorine is mixed with water, it forms hydrochloric acid, which is commonly known as muriatic acid, and also hypochlorous acid, often regarded as the killing chlorine form. The purpose of the chlorine is to eliminate bacteria found in the water.
When not taken care of, these bacteria stimulates the growth of algae and also carries diseases. Chlorine achieves this by corroding the bacteria and any other waste materials in pool water.
Rust is oxidation that’s in progress. In essence, oxygen dissolves the materials it comes in contact with. The sanitizers “rusts away” the bacteria in the water.
Basically, chlorine eliminates 99.9 percent of microorganisms that causes pathogens (fungi, bacteria, protozoan parasites and fungi) from your pool. Moreover, disinfectants are quite effective when it comes to killing algae.
Forms of chlorine
Sodium hypochlorite – this is a chlorine-releasing disinfectant that’s liquid in nature, and is one of the most, if not the most, common disinfectants that’s used in pool treatments. Its popularity has largely been attributed to its low costs as well as the convenience when it comes to its usage.
The hydroxide ion in the disinfectants reacts with the spa or pool water, raising the level of PH. 10-12% (ACC) (available chlorine content) with a PH level 13 is normally the strength that’s used in a pool. The PH should always be corrected with the application of an acid such as hydrochloric acid or a C02 injection.
Calcium hypochlorite – this is a dry form of chlorine, which is available in briquette form or granular tablet. The available chlorine content (ACC) varies from 65-78%, depending on how the substance is manufactured.
It is often used to superchlorinate the water based on its moderate solubility and a high ACC (65-78%). A pound of Calcium Hypochlorite with an ACC level of either 78% or 65% dissolved with 10,000 water gallons delivers 9.4 ppm or 7.8 ppm, respectively.
Lithium Hypochlorite – this is a granular, dry chlorine compound, that’s highly soluble, which makes it the perfect choice for chlorination. Lithium hypochlorite isn’t that common given its low active strength of twenty nine percent, equivalent to 35% ACC, and also its costs, which is pretty high.
The compound dissolves pretty quickly, which makes it the ideal substance to use in painted, fiberglass or vinyl-lined pools.
Chlorine gas – basically, chlorine gas contains both 100% ACC and 100% active chlorine strength. The gas reduces the PH level in the water rapidly, destroying the buffering capabilities in the pool.
Also, the gas is not that easy to handle and its toxicity level is extreme, which is the reason why it isn’t that popular.
These are just some of the most common chlorine forms. Due to its ease of use and its low cost, liquid chlorine is very popular among many pool owners.
