History of Potable Aqua:
Potable Aqua iodine water disinfection tablets were developed by Harvard University in conjunction with the U.S. Army in the 1940s, and have been used by the military for Emergency Drinking Water disinfection for over 50 years. Pharmacal currently supplies the U.S. Military with Potable Aqua for its emergency drinking water needs. Recommended for emergency treatment of water, it makes water bacteriologically suitable to drink. Potable Aqua is widely used by campers, backpackers and various militaries around the world. With the addition of the Potable Aqua Traveller and Chlorine Dioxide Water Purification Tablets, we continue to meet the ever-changing needs of today's outdoor enthuisist.
What is Potable Aqua?
Potable Aqua® Drinking Water Germicidal Tablets make water bacteriologically suitable for drinking. They contain iodine in a proprietary compound called TGHP (Tetraglycine Hydroperiodide). Each tablet contains 20 milligrams of TGHP, which liberates 8 milligrams (ppm) of titratable iodine. As indicated by label directions, the recommended dosage of Potable Aqua is two tablets in one liter or quart of water. When the tablet dissolves in water, it releases both free iodine and hypoiodous acid. Both are effective germicidal compounds. Potable Aqua tablets also contain a buffering agent that brings the pH of the water to a slightly acidic level to optimize the disinfecting properties of the iodine.
How does work?
Each Potable Aqua tablet contains 20 milligrams of Tetraglycine Hydroperiodide (TGHP), which liberates 8 milligrams (ppm) of titratable iodine. Dissolving Potable Aqua tablets in water releases the iodine bound in the TGHP molecule.
When dissolved, both diatomic iodine ((I2) and hypoiodous acid (HIO) are released. Because the tablets contain a buffer, the treated water is maintained at acidic conditions with an approximate pH level of 5.5. Diatomic iodine is more abundant than hypoiodous acid. This mixture provides adequate disinfection of most waters.
Chemical reaction rates, and consequently germicidal effects, are subject to variables such as water temperature and level of contamination in the water. For this reason, two tablets of Potable Aqua and a 30-minute waiting period are required before drinking the water. The iodine works by penetrating the cell wall of the microorganism, therefore rendering it inactive. |
