UF Membrane* Assisted Device for removal of Iron |
||
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 Department of Natural Resources (DNR), iron is considered a secondary or "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 a simple, cost effective, process adaptable at both domestic and community level and is capable of dealing with high levels of iron contamination. The technologies of UF membrane device used in this process are already available at domestic level (Dead-end element type) and at community level (Back washable flow element type) as separate technologies with Bhabha Atomic Research Centre (BARC). Alternately, these devices can also be procured directly from manufacturers who are manufacturing and marketing these devices in various capacities and configurations as BARC's licensees.
