Across large parts of India, groundwater is the only reliable water source — and across most of those parts, that groundwater carries dissolved iron and manganese well above acceptable limits. An Iron Removal Plant (IRP) takes that yellow-brown borewell water and gives you back a clear, usable feed for downstream processes — drinking, cooling, RO pre-treatment or general industrial use.
Iron in groundwater is invisible at the borewell head. It's dissolved as ferrous (Fe²⁺) and looks clear. Ten minutes after it meets atmospheric oxygen — in a tank, a pipe, a fixture — it oxidises to ferric (Fe³⁺), precipitates, and leaves rust-coloured staining on everything it touches. Toilets, fixtures, laundry, RO membranes, cooling tower fills.
The acceptable limit for drinking water is 0.3 ppm. Borewells across Maharashtra, West Bengal, Bihar, Odisha and the North-East regularly deliver 2–10 ppm. RO membranes intolerate iron above 0.1 ppm — feed an unprotected RO with high-iron borewell water and you'll be replacing membranes inside a year.
An IRP solves this with deliberate chemistry: oxidise the dissolved iron quickly under controlled conditions, allow it to precipitate, then filter the precipitate out. It sounds simple. The art is in the details — aeration design, contact time, oxidation chemistry, and the filtration media that catches the precipitate without compacting.
Conventional aeration tower, oxidation contact tank, and pressure sand / multi-grade filtration. Robust, low-touch, well-suited to institutional and light-industrial applications.
Catalytic media filters with chemical oxidation (KMnO₄ / NaOCl) and automatic backwash. Required where manganese is also present or iron is above 5 ppm.
Where dissolved organics, H₂S or arsenic are also present alongside iron — ozone-assisted oxidation followed by media filtration delivers a polished output.
Reliable iron-free water for pharmacy, kitchen, dialysis pre-treatment and laundry — without rust staining linen and fixtures.
Iron-free water for guest rooms, kitchens, swimming pools, and air-conditioning. Critical where municipal supply is intermittent.
Protects expensive RO membranes from iron-fouling failure when feed water is borewell-sourced.
Bulk iron removal at the source water tank — protects every household plumbing fixture downstream.
Bulk-water IRPs for naval and military bases on captive borewell sources, particularly in eastern and northeastern regions.
Where borewell water is the source for production processes — iron must be removed before any further treatment can begin.
