1. Introduction to Granular Chlorine Tablets

Chlorine remains the most applied disinfectant because of its broad spectrum of effectiveness against most pathogens. Usually, the term “chlorine tablet” refers to any solid version of a chlorine compound that is generally calcium hypochlorite, trichloroisocyanuric acid (TCCA), or sodium dichloroisocyanurate (NaDCC) and releases active chlorine when coming into contact with water. However, granular chlorine tablets have been uniquely formulated to allow a measured dose of chlorine to take on a granular consistency that permits easier handling, faster dissolution, and consistent disinfection.

What Are Granular Chlorine Tablets?

Granular chlorine tablets are processed and pressed into a granular form, which makes them much more versatile in dosing than large puck-style tablets or chlorine powder. They are also widely used for small pools and specialized water treatment applications, such as fine-tuning the chlorine concentration levels.
