Ozone is a powerful oxidizer and when used properly can be effective on large amounts of iron. Similar to aeration, ozone is injected into water via a contact vessel as a pre-treatment to filtration. Ozone generators come in many designs and sizes and a full understanding of the process is necessary for success.

If the water has not been exposed to oxygen, the resins in the softener will remove the iron and manganese ions from the water. If the water contains any dissolved oxygen, the resin can be fouled with iron and manganese deposits.
contact us2012-10-17 · The oxidation of iron and manganese by ozone was studied in the laboratory. Model waters both with and without organic matter were used. Results showed iron to be very rapidly oxidized to an insoluble form in the absence of organic matter. However, in the presence of organic matter the iron was protected from oxidation by ozone and precipitation.

contact usUsing ozone to disinfect water has many advantages. Ozone is up to 2500 times more powerful a disinfectant than chlorine, able to destroy cysts, bacteria and fungus instantly (compared to 30-60 minutes with chlorine) and destroys bio-films better than chlorine. Though ozone does not remove manganese or iron from water, it does oxidize these metals to facilitate their removal.
contact usIron removal plants can be based on different filtration media, depending on the iron and manganese concentration, the oxygen level, CO2 content and hardness of the water. Plant principle: First, air is injected in order to oxidize the iron. The oxidized iron will then precipitate on a sand filter. An MnO2 layer in the sand bed will catalyze ...

The combination of these contaminants is sometimes referred to as the "troublesome trio." In Canada and the United States the maximum permitted concentration in drinking water is 0.3 ppm for iron…

However, this water had 3 PPM of iron, 0.5 PPM of manganese and was high in hydrogen sulfide odors. The maximum recommended levels for drinking water is 0.3 PPM iron, 0.05 PPM manganese and no detectable hydrogen sulfide.
contact usComplex bound iron and manganese, e.g. complex bound with humic acids, can be very difficult to remove. In this case oxidation with ozone can be a solution. Manganese removal. For manganese removal only, Manganese dioxide (MnO 2) is used as an adsorbent according to the following reaction: Mn + MnO 2 (s) --> 2 MnO (s)
contact usphysical-chemical iron removal. This technique, with air oxidation and filtration, has been in use for many years, particularly on well water. If necessary, it can be supplemented by adding a number of other treatments such as: pH correction, …

Peroxide did not oxidize the manganese and it created massive complications with chlorine used for disinfection. The chart above shows the manganese removal results from different injectants used.

contact usThe Iron Blaster removes sulphur and iron from water. It is six times more powerful than traditional chlorine water treatment and roughly 3,000 times faster. The Iron Blaster uses a specific media in conjunction with an ozone generator to remove sulphur and iron from water. The Iron Blaster is used to remove or reduce the following: Sulphur. Iron.
