Inspect the Water
In order to figure out the best iron removal conditioner for a particular well, it is important to first know the form of iron that is present. There are two types of iron rich water, and each requires a different type of filtration.
The presence of iron in the well water can be in the ferrous form, which is totally dissolved and cannot be seen, or in the ferric form, where it can be seen when it precipitates. Analyzing the water and identifying the type of iron problem will help determine the appropriate method of conditioning the water supply.
Removing Ferrous Iron
When the water supply is contaminated with iron in the ferrous form, where the iron has completely dissolved and can't be seen, a softener has to be used to remove the iron. In this process, the water is filtered through a water softener, which filters the water with salt to remove any heavy metals.
This process of conditioning the water for iron removal is called an Ion Exchange. When the water is pumped out of the well it passes through a high-pressure tank, so that no air comes into contact with the water.
After that it passes through the compartment having an ion exchanger and a layer of cation-exchange resin to capture the ionized iron that falls from the water. This method of water conditioning will remove even microscopic specs of iron from the water.
Removing Ferric Iron
In the event of the water having a ferric form of iron, an ion exchanger will not work because iron is not dissolved. Ferric iron will more easily clog filters, meaning that it requires special treatment to break down the iron deposits in the water.
For removing the ferric form of iron, you have to raise the pH level of the water, as this will make the iron precipitate more easily. To do this, introduce an alkali to the water and use an aeration method under pressure.
The water is then filtered by using manganese zeolite, an oxidizing filter, which helps in the precipitation process.
Consider Professional Help
Extensive cases of iron contamination may be more than the average homeowner is prepared to deal with on his own. Various processes and filters are now available from different companies, and they do an effective job of iron removal.
These companies also provide an analysis of the water and will suggest the best iron removal conditioner for well water. In extreme cases, it may be necessary to consult a professional.
