Activated charcoal is readily available on the market. It absorbs all the impurities and leaves clean water on being added to the water sample. You can buy an activated charcoal filter easily. Because of its abilities activated charcoal filters toxins but not the benefiting salts and minerals. It is easy, efficient as well as cost-friendly to use one.
Oxidation and Filtration
This method is a two-step process. First, iron ions present in water are oxidized to insoluble forms. Once the oxidation process of iron, the iron turns into an insoluble form and gets separated from the water. The next step is filtration.
The separated insoluble iron is then filtered out from the water and becomes free from contamination. This two-step process is helpful in the removal of iron, and the considerable advantage is that it is very cost-effective.

This method involves the introduction of air to water. When air is passed into the water containing iron, it interacts with the iron ions and causes the oxidation of these ions. They turn into insoluble forms on oxidation, which are then removed by filters.
This is quite a popular and effective technique.
In reverse osmosis, the water goes through a semi-permeable membrane which removes even the smallest of iron particles and provides iron free well water that is safe for consumption.

Why Remove Iron From Well Water?
Iron may be the 4th most abundant mineral in the earth’s crust, but it is an unwanted mineral in well water. When present, even in quantities as low as 0.3 ppm, it significantly affects the overall quality of the water.
The iron presence in well water causes a significant problem for people who depend on well water for their water supply.
How Does Iron Get Into Wells?
We already know that iron is one of the earth’s crust’s most abundant naturally occurring minerals. It can be found in a variety of places.
Well water is the water that comes from beneath the ground. There’s a threshold of groundwater that is stored underneath the ground surface. Wells are structures that are created to utilize this groundwater for human activities.
Bored Wells are made by digging up the ground surface and creating a large-sized hole that can store water. Water supply in such wells is usually by groundwater and rainwater.
When rainfall occurs, the water flows and sweeps the minerals present in the earth’s crust that it comes in contact with. Some of this rainwater goes directly to the wells, while the rest of it adds to the groundwater levels.
In some regions, soils may have higher mineral content. When rainfall occurs in such areas, the flowing rainwater may gain minerals by coming in contact with the ground surface.
This water with high mineral content (like iron) adds to the groundwater and well water. And this way, iron gets into well water and contaminates it.

Types of Iron Present in Well Water
As we know by now, iron is an unnecessary pollutant present in water. Iron may be present in water in various forms, and each may affect the quality of water in its way.
The three different forms of iron present in water are discussed below:
Ferrous IronFerrous iron is an ionized form of iron. Ferrous is soluble iron and easily dissolves in water. This one is also called clear water iron, as it does not give color to fresh running tap water. Although, if the water is kept stagnant red or brown color may be observed. The color occurs due to the oxidization of iron. The appearance of color becomes of great help when testing for the presence of iron in water samples.
Ferric IronThis is yet another ionized state of iron. It is called red water iron and causes red or yellow colored pigmentation of running water. Ferric iron is also insoluble and may not dissolve well in water. The pigmentation helps to identify if the water is iron-contaminated water. If you notice your toilet bowl or sink or any clothing item has acquired a brown stain then it is likely that you have water with iron contamination.
Organic IronOrganic iron may be brown, yellow, or even colorless. It is likely to be found in shallow wells or wells affected by shallow water. It is called organic iron because it is closely associated with organic microbes. Several bacteria feed off of organic iron.
How to Test Your Water for Iron Concentration
As we have established, iron is a harmful contaminant in water and may cause considerable damage in many ways. The first step was to become aware of the harmful effects of iron. The next is to identify if your water is contaminated or not.
And if yes, then what are the iron levels in your water? To what extent is it contaminated? There are some effective ways by which one may detect water iron particles dissolved in their water. Some such methods are listed here:
What Different Kind of Oxidizing Media Is Used In Iron Filters?
An iron water filter is a specially designed equipment that is used for the removal and elimination of iron from water. By separating the iron, these help enhance water quality and make it safe for consumption.
Here’s one Redditor telling the importance of iron filters:
Iron filters are of various types and work by various mechanisms. Some of these filter types are mentioned below:
The most commonly used oxidizing media:
Greensand is a sandy rock or sediment that contains a high percentage of the mineral glauconite. Glauconite is a mineral that forms in shallow marine sedimentary deposits and can range in color from greenish-black to blue-green.
Manganese greensand is an excellent oxidizing agent and helps oxidize iron and convert it into particulate matter.
This is an alternative for manganese greensand. The “Birm” granular filter media is used in these filters hence the name. It’s made of natural pumice mineral with a manganese oxide coating. It removes iron without a chemical oxidizing agent but needs optimum conditions with water and elevated pH to work efficiently.
Calcite is often used to maintain elevated pH. Calcite helps keep the pH level on the higher side and makes the conditions optimum for the filter to work.
As the water passes through the Birm media filter tank, the dissolved oxygen reacts with the dissolved ferrous iron compounds to form an insoluble ferric hydroxide. If there is enough oxygen in the water, as iron-containing water flows through the media, the Birm causes the iron to form rust or solid particles of iron.
Once these rust particles become trapped in the filter media, they are automatically backwashed out to drain once or twice a week, and the filter media is ready to filter again.
KDF is an abbreviation for Kinetic Degradation Fluxion. It is effective with slow flow rates and lower volumes of water.
They are not only effective at iron removal but are also very useful in eliminating other unwanted minerals. KDF Filters are designed to eliminate iron and other impurities like chlorine and hydrogen sulfide by the ion-exchange method.
KDF media turns these harmful contaminants into harmless components making the water safe. KDF media are very effective and can remove up to 98% of cations dissolved in water samples.
How Can You Remove Iron From Drinking Water?

Contaminated water with impurities like iron is not suitable for drinking, and hence elimination of iron from drinking water is indeed an important task. There are many ways in which you can remove iron from drinking water.
Some of these include:
Use of Filtration Systems
The use of filtration systems for cleaning drinking water is the most common method for making drinking water safe for consumption.
In this method, specialized equipment is designed and used. Water is passed through these filters, which trap and separate iron and other impurities and provide you with clean and healthy drinking water.
This is the most effective method to treat hard water. Hard water is such that it has heavy metal and other strong impurities like iron which alter the overall quality of water. Hard water makes water unfit for any use.
Hence, hard water is treated by softening to make it suitable for use. In softening, water is treated with chemicals. These chemicals cause ion exchange and take up all the harmful impurities from the water, making it suitable for utilization.

It is yet another effective method of cleaning drinking water. Iron in drinking water may be present in the form of organic iron. This implies that the water must contain other organic impurities like microbes and parasites.
Chlorination is the method that removes microbes, bacteria, parasites, etc., from water. In chlorination, chlorine is added to the water sample.
This added chlorine eliminates many microbes, bacterial iron, and parasites. However, keeping the chlorine levels in water under check is vital as higher chlorine levels may cause health issues.
As the name suggests, Ozonation is water treatment by infusion of ozone gas. Ozonation is a type of advanced oxidation that generates highly reactive oxygen species capable of attacking a wide range of organic compounds and all microorganisms.
Ozone water treatment has numerous applications due to its effectiveness in disinfection and degrading organic and inorganic pollutants.
Whole house iron filter systems
