Aquamat Iron Removal Filter (AIF) Auto


By mass, iron is the most abundant element in (or on) the earth. It is therefore not surprising that iron is so frequently found in ground water. When water is contaminated with iron it causes stains on surfaces it comes in contact with due to oxidation. Iron at elevated levels in drinking water is a confirmed health risk and should be removed prior to drinking





Aquamat AIF units are meant for reduction of Iron(Fe) impurities, it is based on catalytic oxidation filtration using a manganese dioxide (MnO2) based media. The media acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds, resulting in the iron to precipitate and can then be easily filtered out.

Filter Performance

Other advantages include; long material life with relatively low attrition loss, a wide temperature performance range and extremely high removal efficiency. Minimal labor costs are involved because Birm® does not require chemicals for regeneration, only periodic backwashing is required which occurs automatically.

Equipment Maintenance

Regular backwashing. It is essential to ensure incoming and outgoing water connections, as well as wastewater discharge line.


Feed water enters the unit and passes through the manganese dioxide (MnO2) based media to reduce and eliminate suspended Fe. Iron removal capacity results in longer filter runs, with a substantial savings in backwash water and time out of service. Periodically, the media is backwashed to remove any accumulated particulate matter.

This process is automatic via the backwashing valve.

Birm® is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity fed or pressurized water treatment systems. Birm® acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds. In ground waters the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide and is not filterable. Birm®, acting as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++ and produces ferric hydroxide which precipitates and may be easily filtered. The physical characteristics of Birm® provide an excellent filter media which is easily cleaned by backwashing to remove the precipitant.
