Making up at least 5 percent of the earth’s crust, iron is one of the earth’s most plentiful resources. Rainwater as it infiltrates the soil and underlying geologic formations dissolves iron, causing it to seep into aquifers that serve as sources of groundwater for wells.
Iron is mainly present in water in two forms: either the soluble ferrous iron or the insoluble ferric iron. Water containing ferrous iron is clear and colorless because the iron is completely dissolved. When exposed to air in the pressure tank or atmosphere, the water turns cloudy and a reddish brown substance begins to form. This sediment is the oxidized or ferric form of iron that will not dissolve in water. Although a low level of iron cannot harm your health, it contains bacteria. In addition to this,
Health Effects of Iron
Iron is not hazardous to health, but it is considered a secondary or aesthetic contaminant. Essential for good health, iron helps transport oxygen in the blood. Most tap water in the United States supplies approximately 5 percent of the dietary requirement for iron. However, High iron in water content leads to an overload which can cause diabetes, hemochromatosis, stomach problems, and nausea. It can also damage the liver, pancreas, and heart.
Measuring Iron in Drinking Water
Dissolved ferrous iron gives water a disagreeable metallic taste. When the iron combines with tea, coffee and other beverages, it produces an inky, black appearance and a harsh, unacceptable taste. Vegetables cooked in water containing excessive iron turn dark and look unappealing.
There are many Iron-removal technologies of various scales available for water treatment. They can broadly be categorised as household-level filters, community-level treatment plants, dug-wells and ponds and piped water supply schemes. You can also choose Russian Technology Water Filters to remove Iron and other hazardous contaminants from drinking water.
