Air is injected into the water line and then the air injected water goes into a tall thin filter tank that collects the sedimentary iron and periodically cleans itself of the iron sediment it has collected and sends it down the drain. You also see these filters to remove other unwanted substances such as sulfur and manganese.
How do air injectable water filters work?
The main type of air injection filter we see is a filter designed to remove iron. Air is injected into the water line and then the air injected water goes into a tall thin filter tank that collects the sedimentary iron and periodically cleans itself of the iron sediment it has collected and sends it down the drain.
How does air injected iron cleaning work?
Air is injected into the water line and then the air injected water goes into a tall thin filter tank that collects the sedimentary iron and periodically cleans itself of the iron sediment it has collected and sends it down the drain. You also see these filters to remove other unwanted substances such as sulfur and manganese.
What is air injector tank system?
Air Injector Tank System Air Injection is the chemical-free way to boost oxidation of dissolved Iron, Hydrogen Sulfide, and Manganese in water. This product pays for itself, because you never need to buy or work with chlorine bleach or other chemicalsfor this system.
How does the AIO air injection filter system work?
As water passes thru the air pocket, iron and sulphur are oxidized. The AIO filter media bed then removes the oxidized iron and sulphur from the water. Additionally, dissolved oxygen is added to the water. The AIO Air Injection Filter System, as a single tank system, is an efficient and cost effective system.
How often should my iron filter regeneration?
every three daysThe insoluble flakes of iron that result are then caught by the filter bed. The iron-free water then flows to your faucets. This iron filter replenishes itself every three days in a process that washes the stored iron out of the filter bed and down the drain while refilling the compressed air bubble.
How long does iron filter last?
15-20 yearsA: We typically see Iron Curtain Filtration Systems have a life expectancy of 15-20 years. The Iron Curtain System is the technology that we most frequently recommend for iron filtration and odor in private well water applications.

How do you remove iron from well water naturally?
Filtration is the best way to remove this while also removing: sand, mica, dirt, or sediment if present in your well water. Sometimes the Kinetico® Mach Super Kit cartridge filter can work in removing ferric iron. If levels are high a chemical-free backwashing filter is a better filtration option.
What kind of water filter removes iron?
The only safe and effective way to remove iron from the water is by utilizing an iron filter. A Katolox filtration system is able to remove both forms of iron, magnesium and hydrogen sulfide present in well water.
Does chlorine remove iron from water?
Overall, if your iron is not over 8 ppm, chlorine injection can be an economical method of removing iron from your well water.
How does aeration remove dissolved iron from groundwater?
The scrubbing process caused by the turbulence of aeration physically removes dissolved gases from solution and allows them to escape into the surrounding air. Aeration also helps remove dissolved metals through oxidation, the chemical combination of oxygen from the air with certain undesirable metals in the water.
How do you treat high iron levels in water?
Ferrous (Clear-Water) Iron Treatment 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. Manufacturers report that some water softeners can remove up to 10 mg/L.
How does a water iron remover work?
An iron filter works much like a water softener When water passes through the bed, the media attracts soluble ferrous iron and converts it to an insoluble state. That allows a filter to capture the iron precipitate, leaving the water iron-free.
Does reverse osmosis remove iron from well water?
While RO systems can also help remove iron from drinking water, too much iron in the feed water supply could plug the system, making whole-house well water filtration systems the better primary choice for iron-specific issues. If iron levels are low, RO can work alone to improve the taste of your drinking water.
How can you tell if there is iron in your water?
9 Signs of Iron in Drinking WaterDiscolored Water. High levels of iron change the color of the water. ... Rotten Egg Smell. ... Reddish-Brown Stains on Clothes. ... Fixtures or Sinks Have Rust Stains. ... Pumps and Pipes are Clogged with Slime. ... Water Has Metallic Taste. ... Your Skin Is Excessively Dry. ... Your Teeth Are Yellowing.More items...
Do carbon filters remove iron?
A carbon block filter's ability to remove contaminants depends upon the filter micron rating. Some carbon block filters rated at one micron or less (meaning they have a very small pore size) are certified to remove lead, iron, arsenic, cysts, and coliform bacteria.
What media do water softeners use?
Instead of resin in the tank, these companies utilize media like Birm, Filox, Katalox, Pyrolox or Catalytic Carbon which provide an area for iron to oxidize; and. Instead of brine, the water softener valve draws air (which contains oxygen) into the media tank where it oxidizes the iron (allegedly). That’s how it works and it really sounds great, ...
How much oxygen is in air?
Here’s the problem: Air is about 20% oxygen. 100% oxygen is a wonderful oxidizer, but air is 20% of that. If you had an oxygen concentrator, you could make 100% oxygen and the results would be amazing. But, that would add about $3,000 to every system and the cost would become prohibitive.
Where is water pumped into a packing bed?
Raw, pressurised, water, is fed into a mixer that receives a supply of pressurised air. The water-air mixture is sent to the bottom of the packing bed. Any excess air is discharged to the atmosphere through a pressure relief valve. The water is collected from the top part of the column (photo 5).
What is the purpose of a pressurised aerator?
pressurised aerators. These appliances are often used to remove iron from ground water extracted at deep levels. The closed oxidation column consists of a bed of volcanic rock laid over a plenum plate. (see also Iron removal ). Raw, pressurised, water, is fed into a mixer that receives a supply of pressurised air.
How high can water be aerated?
Water can also be aerated by “bubbling” large amounts of into a shallow height of water (0.25-0.30 m in drinking water). However, with this process air flow rates can be 30 to 60 times higher than the water flow rates.
How does air in a water line work?
Air is injected into the water line and then the air injected water goes into a tall thin filter tank that collects the sedimentary iron and periodically cleans itself of the iron sediment it has collected and sends it down the drain.
What happens when you use treated well water?
Air is left in the treated well water: If air is in the water as it travels through the home, it can collect in any place that holds water. For example: if you use the water to shower the water brings air into the water tank. When the water stops after the shower there are millions of tiny air bubbles left in the water.
Why does my hot water tank spit?
These bubbles rise over time and leave a big air bubble in the top of the tank. This can be a lot of air over time that builds up. When the hot water is turned on again, the air can make the pipes “SPIT.”. Most homeowners do not like pipes that spit hot water.
Does Terminox need air injection?
Air Injector ads air into the water which can introduce bacteria/organics into the water line. Terminox®ISM iron and sulfur filters need no air injection. The use of air injection in well water that has iron, sulfur, manganese etc. is very common.
How are water and air mixed?
First, the water and air are thoroughly mixed in a de-pressurized atmosphere. Second, the volatile impurities are discharged through an exhaust. Third, the depressurized vessel is re-pressurized with a jet pump and pressure tank system.
Which is the least expensive method of injecting air?
Each method is described herein. 1. Venturies (micronizers) are the least expensive method of injecting air, however they can create more problems than they solve. It is necessary to install centuries on the well pump line consequently, all of the water in the building is aerated.
How many gallons per minute for a filter?
However, the service flow for many common filter media in eight to ten inch diameter tanks is about four or five gallons per minute.
Why should the flow rate of water at the pressure tank be measured accurately?
The flow rate of the water at the pressure tank should be measured accurately because many filter media require approximately twice the backwash flow rate as the service flow rate. Timing how long it takes to fill up a measured bucket is an inaccurate method of attaining flow rates.
How many gallons per minute through a ten inch filter tank?
Hence, forcing eight gallons per minute through a single ten-inch tank may pass iron. In order to govern the flow of water evenly through tanks installed in parallel, flow restrictors may be installed on the outlet side of the filter tanks.
What is oxidation in water?
By definition, according to the Water Quality Association's Glossary of Terms, "oxidation is the loss of electrons from the reducing agent (which is said to have been 'oxidized' in the process). Since electrons carry negative charges, oxidation results in an increase of positive valence.".
What are the steps of removing dissolved minerals from water?
Unwanted elements that are removed chemically from the water go through three steps: Oxidation/Reduction, Precipitation, and Filtration.
What is the water passage closest to the check valve?
The water passage closest to the check valve (2) contains built-in convergent and divergent cones forming a venturi. The venturi causes air to be drawn into the water stream when water is flowing. The second water passage acts as a by-pass. The percentage of water flow allowed through the by-pass assembly is regulated by the valve gate (5) ...
What is the best injector valve?
