iron removal filter

About iron removal filter

• Birm: Acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and iron. It requires no chemical regeneration but needs water with a pH above 6.8 and a high dissolved oxygen level.
• Manganese Greensand: Uses a coating of manganese oxide to oxidize and trap iron, manganese, and hydrogen sulfide. It requires potassium permanganate regeneration to restore its oxidizing capacity. 
• Katalox Light: A high-purity zeolite media coated with manganese dioxide. It provides heavy-duty oxidation, removes iron up to 30 parts per million (ppm), and features a long lifespan. 
• Greensand Plus: An upgraded version of classic greensand that uses a durable silica sand core. It withstands higher differential pressures and works well with continuous chlorine dosing. 

• Iron Removal Capacity: Standard systems efficiently treat dissolved iron levels ranging from 1 ppm to 15+ ppm.
• Operating pH Range: Most media varieties require an incoming water pH of 6.8 to 8.5 to achieve optimal oxidation.
• Flow Rates: Residential units support 5 to 15 gallons per minute (gpm), while industrial configurations handle 50 to 500+ gpm.
• Backwash Flow Requirement: Typically requires 10 to 12 gpm per square foot of bed area to properly expand the media and flush trapped iron. 

• Control Valve: Automated digital controllers handle scheduled backwashes based on time clock cycles or flow volume.
• Pressure Vessel: Constructed from Fiber-Reinforced Plastic (FRP) or fiberglass-wrapped polyethylene to prevent corrosion.
• Distribution System: Features a top diffuser and a bottom hub-and-lateral collector screen to prevent media migration during backwash.
