SYSTEM DIMENSIONS
This filter works by adding oxygen to the incoming water by passing it through a bubble of compressed air. The water is then passed through a special filter bed.
The special media not only increases the pH of the water to enhance iron removal but also acts as a physical barrier to trap iron precipitate.
As more water passes through this iron filter, the oxygen in the unit is used up, and the media gets loaded with iron. The regeneration process then begins in order to replenish
the supply of oxygen, and to backwash the precipitated iron trapped in the media bed.
The iron removal efficiency will be more effective with high pH water.
Optional Media Beds:
•
Birm (BAF Models) - Removes iron and manganese from water. Recommended for high pH water.
• nextSand or Multimedia- Traps precipitated iron from the water. Recommended for high pH water.
• Carbon (BIFC Models) -for reduction for Hydrogen Sulfide
Standard Chemfree Filter (BIF and BIFMN Models)
This special media not only increases the pH of the water to enhance iron, manganese and hydrogen sulfide removal but also acts as a physical barrier to trap iron precipitate.
The filter will automatically adjust the pH to neutral or higher on acid water without an acid neutralizer. The ability to raise pH greatly enhances the filter’s ability to remove
iron efficiently.
Replenishment of this media that raises pH will be required periodically, depending on how low the raw water pH is the amount of manganese (Mn) present in the water and
usage rate. Models ending in ‘M’ are required when raw water has up to 1.0 mg/l of manganese or when pH is below 7.0. Over a period of time, it may become necessary to
add more media to the unit. Adding media is necessary only when water has low pH or manganese is present.
nextSand or Multimedia Chemical Free Iron Filter - (BIFMM Models)
This media acts as a catalyst for the removal of iron and manganese from the water but require pre-oxidation. The water is pre-oxidized from the air bubble on the top of the
tank and 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.
Birm Filter (BAF Models)
The air in the tank will precipitate the iron from water and this filter media will trap the iron particles. Recommended for neutral to high pH water.
Carbon Filter (BIFC Models)
Hydrogen sulfide (H2S) is a nuisance to homeowners and water treatment professionals alike. These add objectionable sulfur-like taste and “rotten egg” odor to drinking
water. Left untreated, it can lead to corrosion in drainage pipes and concrete sewers.
Groundwater systems are the most common drinking water source for sulfide contamination because of the anaerobic environment in which groundwater exists. Chlorination
has been considered the most practical method for POE systems, but is often difficult to implement because continuous chemical addition and ongoing maintenance is
required. The formation of THMs is also a concern.
Sulfide problems in surface water sources are much less frequent because of the natural aeration that occurs in most flowing surface water sources. Aeration is the most
