Potable Aqua tablets are dissolved in water to form a solution for consumption. Add two tablets to one quart or liter of water. Cap loosely to allow slight leakage and wait five minutes. Shake the container briskly so that a small amount of water seeps out to rinse the screw threads.
HOW DOES POTABLE AQUA 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.
Potable Aqua tablets are to be used as a short-term, emergency treatment for disinfecting drinking water. Potable Aqua should not be used on a long-term, continuous basis.
According to label directions, the recommended dosage of Potable Aqua is two tablets in one liter or quart of water. This dosage is equivalent to 16 ppm of elemental iodine in the water. Since this product is intended for use in emergency situations, extended daily use should be kept to a limited basis and not exceed six weeks.
