Pyrolox oxidative deironing and manganese removal media for water filters

About the media

Pyrolox oxidative media is a granular water filtration media used to remove excess iron, manganese and hydrogen sulphide from water. It is a naturally occurring ore that has been in reliable use for more than 75 years.

Operating principle

Through a natural chemical reaction, the filter media helps to filter out elements from the water that exceed the hygiene standards, making the water clean and fit for consumption! The media works by oxidising iron, manganese and hydrogen sulphide. Once these substances have been oxidised, they become 'trapped' in the filler media and no longer enter the water supply. When the filter media becomes dirty, all the accumulated substances are drained into the sewage system during regeneration process.

Use

It is important that the inlet pressure is not low (recommended at least 2.2 bar) so that the Pyrolox media is properly " backwashed". If the pressure is too low, the filter media may not drain well and may not remove trapped sunstances from the media. As a result, filter wont supply the intended amount of water. It is also important to note that the Pyrolox oxidative filter media for iron and manganese removal is quite heavy compared to iron and manganese removal media "Birm". This is why the relationship between the amount of media and the size of water filter column into which the media is poured is crucial. Because the Pyrolox filter media must have room to expand in the column during the regeneration. The correct ratio of media to filter column size will ensure a reliable and long service life.

Advantages and disadvantages

The biggest advantage of the Pyrolox deironing media is that it works over a wider pH range than other medias. For example, "Birm" iron removal media works in a narrower pH range compared , to Pyrolox. Therefore, at lower pH levels, Pyrolox will perform better than other medias of the same purpose. The drawback of this media is its weight. Pyrolox is a heavy filter media, which results in higher water consumption during water filter regeneration process. This is primarily because a heavier media is more difficult to recover and return to its original state before it has accumulated excess material from the incoming water. A heavier weight also means that the filter is more difficult to service in the event of a failure. Here "Birm" takes the upper hand. Being lighter makes it easier to loosen the collected substances. Also the amount of water consumed during regeneration is lower and maintenance is easier.
