Dissolved (ferrous) iron is invisible when water leaves the borewell and turns yellow-brown once it meets air, staining tiles, buckets, clothes and sanitaryware. Even a few tenths of a milligram per litre is enough to stain; higher levels foul RO membranes, softener resin and UV sleeves.
An iron removal plant oxidises dissolved iron into a solid and then filters it out. Oxidation is done by aeration, by a catalytic media such as manganese greensand or BIRM, or by chemical dosing (chlorine or permanganate) for higher concentrations. The trapped iron is flushed out by periodic backwashing.
Iron removal always comes first in the treatment train — before softening, RO and UV — because iron fouls all of them. Size the plant from a laboratory test of iron, manganese, pH and hardness and from the daily water demand; the right media depends on the iron concentration and pH.
How to choose the iron removal method
- Low iron with adequate pH — catalytic media (e.g. BIRM or greensand) in a pressure vessel, backwashed periodically.
- Higher iron or iron with manganese — aeration or chemical oxidation ahead of the filter, so the media is not overloaded.
- Iron bacteria or hydrogen sulphide smell — usually needs chlorination ahead of filtration; test for them specifically.
- Automatic backwash valves cost more but stop the media from blinding when someone forgets to backwash.
Note
Installation, commissioning and service response
Commercial buyers are buying uptime, so the commercial terms matter as much as the equipment specification. Insist on these being written into the purchase order rather than discussed verbally.
- Site survey and feed-water analysis before the final quotation — never accept a specification produced without a water report.
- Defined commissioning scope: civil and electrical prerequisites, who supplies what, and a documented performance test at handover.
- Written service response times, with escalation, and clarity on whether spares are held locally.
- Operator training and a laminated SOP left on site, so routine flushing and cartridge changes do not depend on one person.
- Warranty terms stated separately for membranes, pumps, vessels and instrumentation, because they differ.
What a quotation includes
- Raw-water test review: iron, manganese, pH, hardness, TDS and turbidity
- Oxidation method selection: aeration, catalytic media or chemical dosing
- FRP or MS pressure vessel with media, multiport or automatic backwash valve
- Integration ahead of the softener, RO or overhead tank
- Commissioning with before/after iron test and backwash schedule
Why specify with us
Low total cost of ownership
High-rejection membranes, correctly sized pre-treatment and efficient pumps reduce power draw, consumable spend and reject volume. We quote five-year operating cost alongside capex, because that is the number that actually matters.
Heavy-duty SS-304 / SS-316 build
Corrosion-resistant stainless chassis and wetted parts engineered for continuous 24/7 duty, with SS-316 specified where chlorides or process chemistry demand it.
Rapid on-site servicing & AMC
Pan-India installation and service, with written response times and escalation in the AMC rather than verbal assurances — because plant downtime, not the repair, is your real cost.
Custom TDS tuning
Systems engineered against your actual water analysis — brackish groundwater, municipal supply or heavy borewell input, including high-TDS configurations for 3,000+ ppm feed.
Treatment architecture
- 1
Pre-treatment module
Multigrade sand and activated carbon filtration strips suspended solids, turbidity and chlorine that would otherwise oxidise the RO membrane.
- 2
Softening / antiscalant dosing
Protects membranes from calcium and magnesium scaling. On hard feed water this stage is not optional — it determines membrane life.
- 3
High-pressure RO module
Heavy-duty booster pumps drive feed water through industrial spiral-wound membranes at 12-18 bar in an array sized for your recovery target.
- 4
Post-treatment disinfection
UV disinfection and ozonation, with mineral dosing where potable taste and consistency matter.
- 5
Microprocessor / PLC controls
Auto start-stop on tank level, dry-run protection, high and low pressure cut-offs, and timed membrane flushing — with data logging on industrial plants.
