Chlorine dioxide is generated when the Aquamira Water Treatment comes in contact with water. Chlorine dioxide is iodine and chlorine-free. The unique formula works by releasing nascent oxygen, a highly active form of oxygen, which is a strong oxidant and a powerful germicidal agent. Chlorine dioxide has been used by municipal water treatment plants to eliminate a variety of waterborne pathogens since the late 1940s. Unlike free chlorine (familiar as household bleach) or other halogen chemicals (such as iodine), chlorine dioxide does not create potentially harmful by-products.
Aquamira’s key benefits are clearly evident when compared to the other common portable water treatment chemicals such as iodine. Chlorine dioxide is a significantly stronger oxidant than iodine, with greater pathogen eliminating power. Unlike iodine, chlorine dioxide eliminates protozoan cysts such as Cryptosporidium and Giardia which are responsible for over 80% of waterborne illnesses. Chlorine Dioxide does not discolor water, nor does it give water an unpleasant taste. In fact, chlorine dioxide is often used to improve the taste of water by neutralizing unpleasant flavors.
