Filox-R High Performance Media for Iron, Hydrogen Sulfide and Manganese Removal
High performance media for iron, hydrogen sulfide, and manganese removal. No oxidizing chemicals needed for regeneration. Filox-R out performs traditional media such as birm (x7,500) and Greensand. Highest flow rate of any standard iron removal media, 6 gpm/cu.ft service flow; 12-15 gpm/sq.ft backwash rate.
It requires a pH of 7 or more for iron removal and 8 for manganese removal plus a dissolved oxygen level of at least 15% of the iron and manganese content. It is very heavy, and needs a high backwash flow rate to remove the oxidised iron and manganese but gives a high service flow rate and out lasts Birm.

Service flow rate: 28m/hr
Backwash rate: 36 m/hr
Density: 2 Kg/litre

The use of oxidising agents is recommended. Highly reducing waters may cause premature exhaustion. ORP over 170mV indicates Filox-R can be used.
