Przemysłowy filtr żelaza do wody studziennej: Przewodnik wyboru i doboru rozmiaru

This engineering guide shows commercial and industrial users how to design an filtr żelaza do wody studziennej—from diagnosis to process trains, sizing rules and commissioning—so you can remove iron (Fe) and manganese (Mn) reliably and protect fixtures, heat exchangers and downstream processes. It also links to stainless-steel contact tanks oraz valves/media & accessories for immediate specification.

1) Diagnose the Water

Test Fe, Mn, H₂S (odor), pH, temperature and note any iron bacteria (slimy deposits). Record design/peak flow (m³/h or gpm) and the available backwash flow from the pump and drain.

Document seasonal changes; fluctuating wells benefit from the chlorination + contact tank route.

With H₂S lub bakterie żelazowe, plan for chemical oxidation + contact time before filtration.

pH ≥ ~6.8 typically improves oxidation and media performance.

2) Iron Filter for Well Water — When Each Process Fits

An filtr żelaza do wody studziennej is not a single cartridge; it is a process. Choose air injection + catalytic media for low–moderate iron without odor, and choose chlorination + contact tank + catalytic filtration when iron is high, manganese is present, or when odor/iron bacteria must be controlled with disinfection.

Plants with limited backwash capacity can parallel smaller vessels or use chemical oxidation to shift the load from the filter to the contact tank.

3) Proven Process Trains (Commercial/Industrial)

1. Wtrysk powietrza (AIO) → Media katalityczne — low-maintenance for low–moderate iron without odor.
2. Chlorowanie → Zbiornik kontaktowy → Filtr katalityczny → GAC — robust for higher Fe/Mn, H₂S, or iron bacteria.
3. Greensand+/High-MnO₂ with regeneration — stable when Fe & Mn are both elevated; design higher backwash.

4) Iron Filter For Well Water Quick Selection Matrix

Water Condition	Recommended Train	Key Notes
Fe ≤ 3–5 mg/L, no odor	AIO (air injection) + catalytic media	Simple O&M; verify backwash capability
Fe > 3–5 mg/L or H2S / iron bacteria	Chlorowanie → zbiornik kontaktowy → filtr katalityczny → GAC polishing	Most robust for fluctuating wells; allows disinfection
Fe and Mn both elevated	Greensand+ / high-MnO₂ media (with regeneration)	Design higher backwash; monitor ΔP and bed expansion

5) Fast Sizing: Area, Diameter & Backwash

For catalytic media, a practical starting point is a service rate ≈ 10 gpm/ft² oraz backwash 12–15 gpm/ft². Convert flow with 1 m³/h = 4.403 gpm. Final design depends on media spec sheet, temperature and water chemistry.

Design Flow	Filter Area (ft²)	Suggested Tank Diameter	Backwash (12–15 gpm/ft²)
5 m³/h (≈22 gpm)	≈2.2	≈20″ (e.g., 21×62)	≈26–33 gpm
10 m³/h (≈44 gpm)	≈4.4	≈28–30″	≈53–66 gpm
20 m³/h (≈88 gpm)	≈8.8	≈40–42″	≈106–132 gpm

Wskazówka: If your pump cannot supply enough backwash, parallel smaller vessels or add a dedicated backwash pump. Pair chemical oxidation + contact time to reduce the load per vessel.

Sizing an Iron Filter for Well Water with Limited Backwash

Where drain/pump limits exist, split a single large vessel into two smaller units with staggered backwash. This keeps the filtr żelaza do wody studziennej operating within media expansion ranges while staying inside site utilities.

6) Contact Time (CT) & Dosing

For chlorination, target a free-chlorine residual of ~0.2–0.5 mg/L at the contact-tank outlet (adjust to local code and downstream processes). Provide ~5-10 minut of effective contact time in a baffled Zbiornik kontaktowy ze stali nierdzewnej.

Metering-pump sizing (general):

L/h NaOCl ≈ (Wymagany mg/L jako Cl2 × Przepływ m³/h × 1000) ÷ (Dostępny chlor w roztworze, mg/L)

Example: dose 2 mg/L at 10 m³/h using ~10% NaOCl (≈100,000 mg/L) → 0,2 l/h (plus safety factor for demand swings).

7) Commissioning Checklist

• Verify NaOCl strength; set metering pump stroke and calibration column reading.
• Confirm residual at contact-tank outlet; odor eliminated downstream.
• Backwash each filter until effluent clears; record baseline ΔP.
• Log ORP/free-chlorine, ΔP and flow weekly for the first month.

8) FAQ

Do I need a contact tank or is air injection enough?

A contact tank is preferred when iron is high, H₂S/odor or iron bacteria are present, or when you need disinfection stability.

Which media should I choose?

Katalox Light/high-MnO₂ works well across a wide pH window; Greensand+ is mature and effective with regeneration. Match media to Fe/Mn levels and available backwash.

What about activated carbon?

Use GAC to remove residual chlorine and improve taste/odor, especially after chlorination.

What documents do you provide?

Sizing sheets, media loading charts, start-up/commissioning checklist and maintenance schedule.
