7.5 LBS Bag Iron / Manganise water filter Enough to replace the cartridge of 20" x 4.5" 104121

Product Overview

Iron manganese media, used for removing soluble iron (Fe) and/or manganese (Mg) as well as hydrogen sulfide (H2S) from well water supplies, is a purple-black filter media processed from ceramic zeolite granule. Iron manganese media can be used in a completely closed pressure system with no aeration or re-pumping, or in an open gravity filter system.

The most common methods of operation are continuous regeneration, which is recommended for predominantly iron water.

Physical Characteristics

  • Apparent Density: 1.0 g/ml
  • Shipping Weight: 2.5 Lbs
  • Specific Gravity: 2.5~2.6
  • Screen Grading (dry): 16~30 mesh
  • Effective Size: 0.65 ± 0.05mm
  • Uniformity Coefficient: Less than 1.5
  • pH Range: 6.2 ~ 8.5
  • Maximum Temperature: 25 C°
  • Maximum Pressure Drop: 0.85 kg/cm2

Methods of Operation

Continuous regeneration:Continuous regeneration operation is recommended for well water where iron removal is the main objective with or without the presence of manganese. Briefly, it involves the feeding of predetermined amount of potassium permanganate ( KMnO4 ), usually in combination with chlorine ( Cl2 ), directly to the raw water prior to the unit containing Iron manganese continuous regeneration. The chlorine should be fed upstream of the KMnO4 with a contact time of 10 ~ 20 seconds if possible. Sufficient chlorine should be fed to produce the desired residual in the filter effluent. Enough KMnO4 should be fed to produce a “just pink” color in the filter inlet. This will maintain the Iron manganese n media in a continuously regenerated condition.

The quantity of Cl2 and KMnO4 required can be estimated as follows:

mg/L Cl2 = mg/L Fe
mg/L KMnO4 = (0.2 x mg/L Fe)(2 x mg/L Mn)

Without Cl2 the KMnO4 demand can be estimated as follows:

mg/L KMnO4 = (1 x mg/L Fe)(2 x mg/L Mn)

Suggested Operating Conditions

  • Backwash: Sufficient rate using treated water to produce approximately 30% bed expansion.
  • Rinse: At normal service flow rate for 5 minutes or until effluent is acceptable.
  • Capacity: 350~500 g/m2 of bed area based on potassium permanganate demand. For iron/manganese continuous regeneration, a 70cm minimum bed of specially sized iron/manganese media is required. Pressure drop should not exceed 0.70 ~ 0.85 kg/cm2.
  • Flow rate: Normal flow rates with continuous regeneration operation is approximately 5 ~ 12 m/hr. Higher concentrations of iron and manganese usually require lower flow rates for equivalent run lengths. Rates in excess of 12 m/hr can usually be tolerated but a pilot unit should be operated to determine the effluent quality and run length.

The run length between backwashes can be estimated as follows:

Example: What is run length on a water containing 1.7 mg/L iron and 0.3 mg/L manganese at 10m/hr operating rate?

KMnO4 demand = (1 x mg/L Fe)+(2 x mg/L Mn)
=(1 x 1.7) + (2 x 0.3)
= 2.3 mg/L
At 500 g/m2 loading ÷ 2.3 mg/L = 217 m
At 10 m/hr service rate, 217/10 = 21.7 hr

Therefore the backwash frequency is approximately every 20 ~ 24 hours of operation.

General Notes

Raw water having a pH of 6.2 or higher can be passed through iron/manganese media without pH correction; water having a pH lower than 6.2 should be pH corrected to 6.2 ~ 6.5 before passing through the iron/manganese media. If a pH higher than 6.5 is desired in the water system, the additional alkali should be added after the filters due to the adverse react information of a colloid that sometimes occurs with the iron and alkali with pH over 6.5.

KMnO4 solution strength: With continuous regeneration operation, the KMnO4 can be any concentration up to 30 g/L.

Material Safety Data Sheet

Hazards Identification:

  • Inhalation: Excessive concentrations of a nuisance dust may cause nuisance condition such as coughing, sneezing, and nasal irritation.
  • Ingestion: Non-toxic. Large oral doses may cause irritation to the gastrointestinal tract.
  • Skin Contact: Not expected to be a health hazard from skin exposure. May cause mild irritation and redness.
  • Eye Contact: No information found, but presumed to cause mechanical irritation.
  • Aggravation of Pre-existing Conditions: No information found.

First Aid Measures

  • Inhalation: Remove to fresh air. Get medical attention for any breathing difficulty.
  • Ingestion: Not expected to require first aid measures. If large amounts were swallowed, give water to drink and get medical advice.
  • Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops.
  • Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention if irritation persists.

Fire Fighting Measure

  • Fire: Not considered to be a fire hazard.
  • Explosion: Not considered to be an explosion hazard.
  • Fire Extinguishing Media: Use any means suitable for extinguishing surrounding fire.
  • Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode.

Accidental Release Measure

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.

Handling and Storage

Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.

Exposure Controls and Personal Protection

Personal Respirators (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator.

WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin Protection: Wear protective gloves and clean body-covering clothing.

Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
