BM Filter
This media acts as a catalyst for the removal of iron and manganese from the water but require pre-oxidation. This media removes the iron and manganese from the water.
This is not recommended to remove hydrogen sulfide from the water and requires high pH water. The media is not sacrificial hence no replenishment is required.
CAUTION! Do not use where the water is microbiologically unsafe or with water of unknown quality
without adequate disinfection before or after the unit.
Control Valve Regeneration Sequence
The regeneration cycle goes through 3 steps.
1. Backwash (minimum 30 psi inlet pressure required): During the backwash
cycle, water flows upwards through the bed, expanding the media and carrying
any contaminants trapped within it to the drain.
2. Rapid Rinse: During the rapid rinse cycle, water flows downwards through the
bed, settling the media and carrying any precipitated contaminants trapped
within it to the drain.
3. In-Service Position: The unit then returns to the In-Service position. While this
happens water continues to enter the tank.
