Oct 17, 2015  Water Treatment With sodium dichloro-s-triazinetrione dihydrate I researched making water safe with chlorine quite a bit a few months ago and I would like to share what I have found. People have been using the old pool shock, calcium hypochlorite, to do this for some time and it works well except for how caustic it is.

The key difference between trichlor and dichlor is that the Trichlor (or trichloro-s-triazinetrione) is a dry solid compound having the highest possible content (around 90%) whereas, the Dichlor (or dichloro-s-triazinetrione) is available as its dihydrate form or the form.The chlorine content of the dihydrate form of the dichlor is around 56% while the chlorine content in anhydrous form is about 62%. The main use of both these compounds is mainly in cleaning swimming pool water, spa water and hot tubs.CONTENTS1.2.3.4.5. What is Trichlor?Trichlor is the short name for trichloro-s-triazinetrione. Trichloroisocyanuric acid is another name. It is a solid dry compound with the highest possible chlorine content.

It contains about 90% chlorine. People use these compounds to clean water in swimming pools, spa, and hot tubs. Figure 1: Chemical Structure of TrichlorTrichlor adds cyanuric acid to water.

This acid is useful in stabilizing the free chlorine in the water. Since it is a solid containing concentrated chlorine, it provides the residual level of chlorine required to kill pathogenic organisms in water. Moreover, it destroys the contaminants (such as those found in sweat, urine, etc.) found in water. Therefore, it acts as a sanitizer.Trichlor is commercially available in granular and tablet form. Furthermore, this compound is completely soluble in water, and it does not contain any calcium. It is suitable for hard water cleaning as well.

The pH and the total alkalinity of water considerably reduce when we add trichlor to the water. When it dissolves in water, it produces hypochlorous acid and hypochlorite ion (also known as free available chlorine). The hypochlorous acid acts as a biocide. What is Dichlor?Dichlor is the short name for dichloro-s-triazinetrione. This compound is available in two forms as dihyrate form or anhydrous form. The dihydrate form contains around 56% chlorine while the anhydrous form contains around 62% chlorine. Therefore, it is useful in treating water in swimming pools, spa, and hot tubs.Application of this compound to water increases of residual chlorine level required to kill pathogenic organisms in water.

It also acts as an algaecide as well as a sanitizer.Unlike the application of trichlor, the application of dichlor slightly reduces the pH and total alkalinity. This compound is completely water soluble.

It also produces hypochlorous acid and hypochlorite ion when dissolved in water. Dichlor is typically sold in granular form. However, it depends on the its form: dihydrate form or anhydrous form. Din next pro condensed medium download google.
