Assisted Device for Removal of Iron From Contaminated Water for Drinking Purposes

Home » Technology » New Technologies » Chemicals Based Technologies » Removal of Iron From Contaminated Water


Iron is one of the most plentiful resources found in the earth's crust. Rainfall seeping through the soil dissolves iron in the earth's surface and carries it into almost all kinds of natural water supply, including well water. Besides, iron may also enter drinking water through rusted pipes carrying this water.

Iron is not considered hazardous to human health in moderate levels. In fact, iron is essential for good health because it facilitates transportation of oxygen in blood. However, when the level of iron in water exceeds 0.3 mg/l (ppm) limit, people experience red, brown, or yellow staining of laundry, glassware, dishes and household fixtures such as bathtubs and sinks. The water may also have a metallic taste and an offensive odour. Consumption of water with excess iron causes constipation accompanied by other physiological disorders. As per the Department of Natural Resources (DNR), iron is considered a secondary or an "aesthetic" contaminant. Present recommended limit for iron in water, 0.3 mg/l (ppm), is based on taste and appearance rather than on any detrimental health effect.

UF membrane assisted oxidation process for removal of iron from ground/ surface water makes it safe for drinking purposes. It is simple, cost effective, adaptable at both domestic as well we community level and is capable of removing high levels of iron.

The technologies of UF membrane device used in the process are already available as separate technologies at domestic level (Dead-end element type) and community level (Back washable flow element type) with Bhabha Atomic Research Centre (BARC). Alternately, these devices may also be procured directly from manufacturers who are manufacturing and marketing these devices in various capacities and configurations as BARC's licensees.
