This value is often used when it considers water treatment, but what does it mean? Redox stands for Red<\/strong>uction and Ox<\/strong>idation potential, another term is the ORP, which stands for O<\/strong>xidation-R<\/strong>eduction P<\/strong>otential. We now know what it stand for, but what does it mean? It\u2019s hard to explain, but the most important thing it tells us in the world of ozone is the purity of the water and its potential to break down pollution. It is measured in mV and varies from -2000mV to +2000mV. A negative value is practically only used in certain methods to purify water. This page focuses on redox related to ozone (oxidation) so we\u2019ll just focus on positive redox values.<\/p>\n

The redox value is measured by a redox sensor which measures the oxidising potential of the water. It also gives you an indication of the amount of dissolved oxygen in the water. Water that\u2019s heavily polluted contains less oxygen because organic pollution consumes oxygen. This is why the redox potential of polluted water is lower than that of clean water.<\/p>\n

The redox value also gives an indication of the bacteriological activities of the water.<\/p>\n

The redox value is a good indicator of the amount of dissolved ozone in clean water, provided there are no other oxidisers present.<\/p>\n
