For those who prefer the traditional ion-exchange method of water softening, Springwell also has a salt-based water softener for well water owners.

The SpringWell AIO System can remove up to 8 PPM of Hydrogen Sulfide, up to 7 PPM Iron and 1 PPM Manganese. The blue tooth control head allows for programming of backwashing cycles and features a slow release of the compressed air charge prior to backwash cycles eliminating the loud explosive blast that is among typical outdated systems.

For those who have a ferric or ferrous iron level less than 7 ppm, a pH level greater than 6. Also removes hardness, manganese, sulfur, and all the minerals associated with well water.

For well owners with a high amount of Iron, Manganese, and Hydrogen Sulfide, the Crystal Quest whole house iron filter may be the best solution.

The fiberglass tank holds 48, grain capacity of glauconite green sand. Soluble iron and manganese are oxidized and precipitated by contact with higher oxides of manganese on the CQ-IGS granules. The hydrogen sulfide is reduced by oxidation to an insoluble sulfur precipitate.

Precipitates are then filtered and removed by backwashing. Well owners with manganese, hydrogen sulfide, and problematic iron greater than 3 ppm may want to consider the Crystal Quest iron filter for whole house treatment. While the iron found in groundwater is largely considered innocuous for human consumption, the damage that iron can cause in home plumbing systems and fixtures can be severely problematic and costly.

There are several different methods for removing iron from a drinking water supply, and while all have their own benefits, it is important to understand the make-up of the water supply in order to correctly apply the right system.

Testing the water will determine the levels of iron as well as any other contaminants that may need to be addressed. Water softeners, iron filters, and chemical feeds are all effective methods for removing iron when used for the right application.

Tips and Warnings. Related Articles. Article Summary. Co-authored by wikiHow Staff Last Updated: December 4, Approved. Method 1. Test your well water to determine the best water purifying option. Before you determine how to filter your water, send a sample to a laboratory for testing.

This will give you a better idea of what harmful minerals besides iron are in your water and help guide you when choosing a water purifying system.

Choose a water softener exclusively for removing iron. Water softeners are generally equipped to replace iron with other minerals in water but may not remove more harmful minerals, like arsenic or sulfur.

If you have tested your well water and found other minerals besides iron in it, another option might suit your needs better. Avoid water softeners if you are on a low sodium diet.

Water softeners work by replacing iron minerals with sodium, and they require salt to work. If you cannot currently handle a high sodium diet, another iron removal method like oxidation filtration or reverse osmosis might be ideal.

Install a water softener system yourself or call a professional. Every water softener system is different—some are simply attached to your well water pump or faucet and can be installed on your own.

Others, however, may require professional help to install. Read your model's instructions and, if you are unsure how to properly install the system, call a plumber or the company you bought the system from for assistance.

Use high-purity salts in your water softener. While purchasing water softener salt, look for high-purity options like evaporated or solar salt. These will leave less of a residue in your softener tank. Some water softener salts are made specifically for high iron concentrations.

Check the label to find the right salt for your water. Test the well water again after installing a water softener system. After you have installed your water softener system, send another sample to a nearby laboratory for testing. Check for any harmful minerals remaining in the water that your softener system might not have filtered out.

If significant levels of any harmful mineral remain, you may want to try a different filtration option. Method 2. Use oxidation filtration to get rid of iron and arsenic traces. Oxidation filters are generally stronger than water softeners and can remove harmful chemicals that are common to well water, specifically arsenic.

If your well needs to be treated for arsenic and iron traces, choose an oxidation system to filter your water. If you have not tested your well water for arsenic traces, it is recommended for all well owners to do so. High arsenic levels are common in private wells.

Call a plumber or filtration company to install your oxidation filtration system. Research local companies that sell filtration systems and compare their prices for well or home filters. Choose the price that best fits your need and contact the company to install it. If you would prefer to install an oxidation filter yourself, find a product online or at a home supply store that is marked as easily-installable.

If you buy an oxidation filter online, you may be able to call a plumber to help with installation. Handle chlorine-based oxidation filters carefully. Some oxidation filters require the usage of chlorine, a hazardous chemical. Read the filter's maintenance instructions carefully to avoid adding too much chlorine to your drinking water Never touch chlorine with your bare hands, and keep it out of reach from children or pets.

Oxidation filters that use chlorine are better at disinfecting water than filters without chlorine.

Get your well water tested after you have installed an oxidation filter. Send another water sample to a laboratory after installing your oxidation filter and compare its results to the well water's initial lab reading. If your oxidation filter does not seem to be filtering out all harmful minerals, you may need to try a different water purifying option.

Maintain routine care of your oxidation filter. Clean your oxidation filter regularly according to the product instructions to keep it in the best possible condition. If you are concerned about its functioning at any time, send a water sample to a nearby laboratory to make sure it is functioning well.

Method 3. Use a reverse osmosis filter to get rid of multiple mineral traces. Reverse osmosis filters can be helpful for getting rid of iron, manganese, salt, fluoride, and lead. If you have tested your well water and the results contained many different minerals alongside iron, reverse osmosis is likely the best option.

National Institutes of Health Go to source One downside of reverse osmosis filters is that, along with harmful minerals, they can also remove good minerals like calcium from your water supply.

The same thing goes for the dishes that go through your dishwasher. Even in low concentrations, iron can leave similar stains on fixtures, tableware, countertops, etc. Not only are these stains nasty and unpleasant, but they can be difficult to remove.

Water softeners and iron filters are the most effective at removing iron. Three different types of iron can enter your well water.

Removing iron from your well is contingent on a thorough and accurate understanding of what types of iron are present. Iron presents unique challenges and different solutions based on its form. In order to remove it, you must have a firm understanding of what form the iron is in. Performing a water test will reveal exactly what water conditions you are working with, and present you with the clearest path forward.

Iron test strips can also provide you with a more general idea of the parts-per-million of iron present in your well.

There are several options available for removing iron from your water, but the ideal treatment method for your situation will depend on the type of iron in your water, along with other factors.

A laboratory analysis can help determine the extent of the problem and the possible treatment solutions. Here are the 3 Most Common Types of Iron found in Well Water and How to Remove Them.

Also known as clear-water iron. If your water comes out of the tap looking clear but turns a yellow or rusty brown color after sitting out in the open, you may have ferrous iron in your water.

This type of iron is totally dissolved in water and can easily pass through standard filtration systems. It also causes reddish-brown staining in toilets, showers and sinks — especially where water faucets drip.

Water softeners: Ion-exchange water softeners can handily remove low levels of ferrous iron from the water. If you have soft water, an oxidizing filter will be more effective at reducing the iron content of your water. If you are using a water softener to reduce iron content, you will need to periodically flush the system and resin bed with Rust Out to protect the system and ensure the longevity of the resin beads.

Also known as red iron, which turns the water a cloudy orange. When ferrous iron is oxidized it changes to ferric iron. Ferric iron is also known as red water iron or iron that has precipitated out of solution.

This type of iron will also cause staining in the home. Because it is an actual particle it can clog filters, pipes, and showerheads over time. Sediment filters: This solution is ideal for those with low levels of iron, all of which is in ferric form. A sediment filter alone will not solve your stained toilets and metallic tasting water if your well has ferrous iron in addition to the ferric iron.

Which shows up as reddish slime in toilet tanks. Bacterial iron most commonly emerges in wells because of poor maintenance or improper well servicing. These are not common and require very specific types of treatment involving chemical injection and contact time. Professional Treatment: Removing bacterial iron from your well is a labor-intensive process, so if you suspect you have iron in your water, have it tested by a professional so that the proper treatment can be determined.

But regardless of the test results, a premium whole house water filtration system is probably the most effective and economical way to remove iron from your drinking water. Iron may present some concern if harmful bacteria have entered a well. Some harmful organisms require iron to grow.

If there is iron in the water, it may be harder to get rid of harmful bacteria. Yellow or red colored water is often a good indication that iron is present. However, a laboratory can tell you the exact amount of iron, which can be useful in deciding on the best type of treatment.

In addition to testing for iron, it can be helpful to test for hardness, pH, alkalinity, and iron bacteria. Point of reference : Water with an iron level above 0. Minnesota Department of Health recommends you use an accredited laboratory to test your water.

Contact an accredited laboratory to get sample containers and instructions, or ask your county environmental or public health services if they provide well testing services. Search for Accredited Laboratories. Home water treatment is the most common method for controlling iron in water.

You can purchase and install a treatment unit on your own, or you can work with a water treatment professional.

Depending on circumstances, other options may include:. Effectively treating iron depends on the form s of iron present, the chemistry of the water, and the type of well and water system. It is best to work with a water treatment specialist to find the best solution.

Water softeners and iron filters such as a manganese greensand filter are effective at removing clear-water iron. Water softeners are the more common method. A water softener removes hardness minerals like calcium and magnesium. Iron will plug the softener and must be periodically removed from the softener resin by backwashing.

Chemical oxidation using chlorine or hydrogen peroxide and filtration is also used. However, proper dosing can be difficult and carries health risks if improperly dosed. Organic iron and tannins present water treatment challenges. Organic iron and tannins can slow or prevent iron oxidation, so water softeners, aeration systems, and iron filters may not work well.

Chemical oxidation followed by filtration may be an option. Distillation or reverse osmosis can remove any type of iron. If there is a lot of iron in the water, it can quickly plug up the units, so a whole house treatment system may be better.

Iron bacteria are organisms that consume iron to survive. The organisms naturally occur in shallow soils and groundwater, and they may be introduced into a well or water system when it is constructed or repaired. Learn more about how to prevent, remove, and treat iron bacteria at Iron Bacteria in Well Water.

Both natural sources and human activities can contaminate well water and cause short-term or long-term health effects.

Aeration units may work by cascading, bubbling, or stripping the gas from the water. Aeration may be advantageous because it does not add chemicals to the water.

Maintenance costs are low for aeration units but the initial purchase costs are often higher than other treatment options. Aeration units also require a filter for removal of the oxidized iron and manganese which must be backwashed.

The water should also be disinfected to keep bacteria from colonizing the aerator. Catalytic carbon adsorbs then oxidizes and filters dissolved iron in one unit.

It is effective for concentrations of dissolved iron less then 1. Maintenance requirements are less than oxidizing filters because no chemicals are added, but backwashing is still necessary. Catalytic carbon requires a minimum of 4. Some groundwater supplies may need pretreatment to increase the dissolved oxygen concentration.

In recent years, ozonation has received more attention as a method for treating numerous water quality problems. Like chlorine, ozone is a strong oxidant but it is a much more unstable gas that must be generated on-site using electricity.

Once the ozone is produced, it is injected into the water where it oxides dissolved metals which must then be filtered. Ozone units are usually more expensive than other more conventional treatment options but they may be useful where multiple water quality problems must be treated i.

bacteria and metals. While treatment devices are available to reduce iron and manganese from water, other options should not be overlooked.

In some cases, a municipal water supply line may be nearby. Hooking into a municipal water supply may seem expensive initially but it may be economically preferable given the long-term costs and hassles associated with purchasing and maintaining a water treatment device.

Hooking into a municipal water supply will also usually increase the real estate value of your home. Another option may be to develop an alternate private water supply.

Other sources of water like a shallow groundwater spring or a rainwater cistern could be developed to avoid iron and manganese but they may both present other water quality and quantity problems. Alternative sources of water should be thoroughly investigated along with treatment options when choosing a strategy to avoid iron and manganese in water.

How to remove iron from drinking water Catalytic oxidation is a tried and tested method of both oxidising the iron to form a precipitate and then holding on to it until it is automatically back-washed to a drain. The rate at which divalent iron is oxidised by oxygen will depend on a range of factors, in particular: temperature, pH , iron and dissolved oxygen levels.

This reaction can be written as follows:. is the partial oxygen pressure and k a constant that depends on temperature and on the raw water buffering capacity. Equation 2 shows that the higher the pH and the closer the water is to its oxygen saturation point, the faster the reaction kinetics.

The reaction time established in the laboratory using synthetic water may be considerably reduced in most plants as the result of certain catalytic effects primarily generated by earlier deposits. Some biological phenomena, discussed further on, follow the same pattern. On the other hand, when humic acids are present, iron oxidation will be delayed.

The precipitate obtained will mainly be hydroxide floc Fe OH 3 , as per equation 1. Consequently, treatment conditions and the performance of filtration that follows on from oxidation may vary widely from one plant to the next.

For all these reasons, under optimum conditions, the effective size of the filtering medium may range from 0. Some substances such as humic acids, silicates, phosphates and polyphosphates, act as inhibitors in the oxidation, precipitation or filtration of ferric hydroxide.

These effects can be overcome using supplementary treatments: oxidation potassium permanganate, ozone , coagulation alum or flocculation alginate or approved polymer according to the case.

Pressurised systems represent the most common type of installation, as illustrated in figure 22 comprising:. Gravity units use atmospheric pressure cascade aeration, sprayed… followed by gravity filtration or pressurised filtration in the latter case, with or without recovery pumping.

Figure 23 shows three examples of construction carried out using this principle with a water and air backwash.

Oxidation can also be carried out using ozone, as in the case of the Crissy plant that includes figure 24 :. A sedimentation step has to be placed between aeration and filtration see example of the Mimizan France system, figure 25 in the following cases:.

Solids contact clarification processes will then be particularly appropriate for treating this water. As an alternative, the lightweight ferric hydroxide floc obtained with groundwater, usually turbidity-free, is also well suited to dissolved air flotation.

Carbonate removal using lime creates a high pH and promotes iron and manganese removal. Accordingly, almost all the ferrous carbonate will precipitate at a pH of 8. Partial carbonate removal at a pH in the region of 8 can, therefore, result in total iron removal.

In some cases, especially in fluidised bed carbonate removal reactor see section the gyrazur, a granular contact mass reactor , the same pH will produce satisfactory manganese removal whereas, in theory, the latter should be combined with total carbonate removal at a pH of 9.

This is the principle used for the Ratingen plant in Germany figure 27 : this plant carries out partial carbonate removal, iron removal, manganese removal and nitrification.

It has been shown see also section iron and manganese cycle and biological iron and manganese removal that, due to the production of enzymes and biopolymers, many bacteria are capable of biologically oxidising iron by catalysing the divalent metal oxidation using dissolved oxygen, even at low concentrations, and by fixing it in their cell membranes, their sheaths, their stalks, etc.

3 Ways to Remove Iron from Well Water - wikiHow In each backwash cycle cleaning cycle , the unit uses as much water as a load of laundry. Then we can see what levels of contaminants are in your water, as well as other competing contaminants, and engineer a system that will work for you. Ferric Iron, also known as red-water Iron, is characterized by the reddish-orange hue it gives to water. Enjoy years of iron-free water.
