TRANS-IRF and TRANS-ACF

TRANSwaters Iron Removal Media contains an active insoluble catalyst to precipitate iron and/or manganese. Under suitable conditions, the iron and dissolved oxygen in water react with the filter bed and as a result the iron is precipitated in the form of hydroxide.

Conditions necessary for the use of Non-Chemical Iron Removal

Iron Removal

Hydrogen Sulphide Removed prior to treatment
Organic Matter BOD (Biological oxygen demand) < 3 ppm
Oil and Grease NIL – To be removed prior to treatment
DO (Dissolved Oxygen) Minimum 15% of Iron
Ph Greater than 6.5
 
Manganese Removal

The removal of manganese from water by the catalytic action of media usually requires a higher pH than is required for iron removal. Such water should have a pH in the range of 8.0-9.0. The dissolved oxygen content should be 15% or more of the total manganese and iron expressed in ppm. Other conditions are the same as for iron removal.
