Iron Removal Filter Parts — Complete Industrial Guide & Catalog

octubre 21, 2025

Water filtration iron removal parts are the service kits, media, valves, tanks and internals that keep iron and manganese filters running reliably. This guide gives you a pro overview of the process train, a parts catalog you can act on, quick sizing & backwash tables, BOM templates, troubleshooting, FAQs, and RFQ links. Use it to scope projects faster and reduce downtime.

1) Where Water Filtration Iron Removal Parts Fit in the Process

Typical industrial train:

Oxidation — air injection (AIO) or chlorination/ozone.
Contact & mixing — stainless-steel contact tank or static mixer.
Catalytic filtration — MnO₂/Katalox Light/Greensand Plus to capture oxidized iron/manganese and suppress H₂S.
Polishing — carbon to remove residual oxidants/odors.

Illustration suggestion (Alt): “Iron removal process train and required parts — AIO/chlorination → contact tank → catalytic filter → carbon.”

3) Quick selection cards

Low iron (≤3 mg/L, no odor): AIO + catalytic media (e.g., Katalox Light); verify backwash capacity.
3–5 mg/L iron or H₂S/iron bacteria present: Chlorination + contact tank → catalytic filter → carbon polish.
Iron & manganese both elevated: MnO₂ or Greensand+; design higher backwash & ORP control.

4) Iron Filter Sizing & Backwash Guide

4.1 Service & backwash rates (reference)

Media	Service rate (gpm/ft²)	Backwash rate (gpm/ft² @ 20 °C)	Notas
Katalox Light	5–12	10–16	Temp-correct: +15–20% @ 10 °C. Good Fe/Mn/H₂S.
Greensand Plus	5–10	12–15	Needs oxidant (NaOCl/KMnO₄) & ORP control.
MnO₂ (dense)	5–10	15–25	High BW demand; check drain hydraulics.
Catalytic carbon	3–6	10–12	Used in polish; chlorine reduction & odor.

Backwash temperature correction: lower water temperature increases required BW rate; confirm with media datasheet.

4.2 Contact time (CT)

When chemical oxidation is used, size contact tank for the target CT (e.g., free Cl: 0.5–2.0 min depending on spec). Add static mixer to improve mass transfer.

4.3 Valve & drain sizing

Match valve port and drain size to peak BW rate.
Verify site drain capacity & backwash pump curve.
Set interlocks for low/high level and chemical feed.

6) Iron Removal Filter Troubleshooting & Replacement Guide

Symptom	Likely root causes	Fast checks / actions	Replace?
Iron bleed-through	Service rate too high; exhausted media; low ORP; channeling; iron bacteria	Drop service rate; verify ORP; shock chlorination; relevel bed; check injectors	Rebed media if performance not recovered
ΔP keeps rising	Fouling by fines/iron sludge; under-rated backwash; cold water	Increase BW rate/time; raise water temperature if possible; flush side strainers	Replace baskets/strain ers if damaged
H₂S odor after filter	Insufficient oxidation/CT; venting issues	Increase oxidant dose; lengthen CT; fix air vent	Polish with catalytic carbon if needed
Valve won’t draw air/chem	Injector clogged; checks failed; seal wear	Clean/replace injector; rebuild checks; install kit	Seal & spacer kit / piston kit

Typical cycles: media 2–5 years (water dependent), seal/spacer 1–2 years, injector/vent annually, gauges/probe O-rings as inspected.

7) Compliance & materials

Use wetted materials compliant with applicable NSF/ANSI standards for drinking water where required.
Check media/vendor datasheets for service & backwash envelopes and safety notes.
Document ORP/free chlorine, flow, ΔP, and backwash events in your O&M log.

8) FAQs

Is AIO enough or should I chlorinate?

AIO works well at modest iron without heavy odor or biofouling. When H₂S, iron bacteria or higher iron are present, chlorination + contact tank → catalytic filter → carbon polish is more robust.

Katalox Light vs Greensand Plus?

Both remove Fe/Mn. KL typically needs less chemical support and handles H₂S well; Greensand Plus typically runs with NaOCl/KMnO₄ support and clear ORP control. Size by datasheet envelopes.

Why is my backwash weak?

Check temperature correction, drain/valve sizing, BW time, and supply pressure. Cold water can require 15–25% higher BW rate.

How often should I replace parts?

Plan annual kits for seals/spacers, injectors, vent checks; rebed media when ΔP, iron bleed or capacity trends indicate exhaustion.
