In tap water, the iron and manganese contents are constant. In almost all cases they are far below the applicable limit values. With water from your own house well, however, the exposure to iron and manganese can be a problem. How to use filters and what to look for is explained in detail in this article.
Occurrence of iron and manganese
Iron and manganese are present in many groundwaters. They are not primarily harmful to health, but lead to an unsavory discoloration of drinking water change the taste very negative.
The two substances are present in nature in different compounds. In the waterworks iron and manganese are often removed by ozonation from the water, it is simultaneously sterilized.
Evidence of iron and manganese in the water
The typical rusty red color of the water also comes from the rust. When iron oxidizes, it forms rust in combination with air and water. The rust particles are so small that they can not be easily filtered out.
A typical sign for manganese are small, black particles in the water. In general, however, only an analysis of the water provides information about the actual manganese content.
limits
According to the Drinking Water Ordinance, a maximum of 0.2 mg / l iron and 0.05 mg / l manganese may be present in the water.
filter systems
Filtering of iron and manganese is only possible with special filter systems. They are designed so that a precipitation reaction takes place in them, with the help of which the iron is oxidized and completely converted into rust, which can then be filtered out as a particle.
Manganese precipitation is a bit more difficult, but it happens on the same basis. There are combination filter systems for filtering both substances from the well water.
Important for the design and dimensioning of the system are the following points:
- Iron content in water (can be measured with test strips)
- Manganese content in the water (there are no test strips for this purpose, it must be determined laboratory-technically)
- pH of the water (can be determined with test strips)
- taken amount of water
Tips & Tricks
It is absolutely necessary to check the water before planning a system, since the type of installation and the design of the filters must also be adjusted accordingly.
FAQ - 💬
❓ Can you filter out iron in water?
👉 A whole house water filter system that is designed for iron removal is the best way to remove ferrous iron from water. The water filter you choose will depend on the level of iron you need to remove. For some homes, a Clearwater Systems whole-house water softener can handle iron removal.
❓ How do you get rid of ferric iron in well water?
👉 Aeration (injecting air) or chemical oxidation (usually adding chlorine in the form of calcium or sodium hypochlorite) followed by filtration are options if iron levels are more than 10 mg/L. Sediment filter, carbon filter, or water softeners can remove small amounts of iron, but the iron will quickly plug the system.
❓ What can filtered water be used for?
👉 Filtering water can not only remove contaminants and debris, it can also make your water taste better. Additionally, it can be a more eco-friendly way to enjoy clean water because it helps you cut down on single-use plastic bottles. Water filtration may further improve some aspects of tap water.
❓ What is the best way to get rid of iron in your water?
👉 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.
❓ How do you remove iron from well water cheaply?
👉 A cheap way to remove all types of iron from your well water is to disinfect it. The cheapest and most effective way to do so is to use a combination of any form of household bleach and white vinegar. Before starting disinfecting your well examine your water for any types of iron, bacteria and microbes.
❓ What is the best filter to remove iron from well water?
👉 For very high levels of ferrous iron, a manganese greensand filter is usually the best choice and can be effective for levels up to 10 to 15 ppm [4]. Water softeners and air injection oxidization can also remove ferrous iron, but only at lower levels.
❓ What do water filters not remove?
👉 It will not remove bacteria. To remove naturally occurring or disinfection tastes and odours from water an activated carbon filter is more appropriate. It will not remove bacteria. To remove chemicals and bacteria, a reverse osmosis or distiller system would be required.
❓ Is filter water good for health?
👉 Water filtration systems are good for your health. The benefits are ten-fold, with skin hydration, nutrient absorption, weight loss, detoxification, digestion and a reduction in the risk of cancer. Drinking pure water helps to support the immune system and mental health function.
❓ Does Brita remove iron?
👉 The Brita PRO Iron Filter Water Softener System highlights: Softens water and removes unwanted iron and manganese. Our most advanced programmable valve head. Hybrid regeneration for efficiency and improved water quality. Softens water and removes up to 10 ppm of ferrous or ferric iron.
❓ Is it OK to drink well water with iron?
👉 The Environmental Protection Agency considers iron in well water as a secondary contaminant, which means it does not have a direct impact on health. The Secondary Maximum Contaminant Level set out by the EPA is 0.3 milligrams per liter, but this is merely a guideline and not a federal standard.
❓ Can ferrous iron go through water filters?
👉 Ferric iron, because of its nature, can be removed by mechanical water filters. Meanwhile, ferrous iron is a whole different story. Because ferrous iron is not oxidized, it still has to be oxidized for it to be removed. IT means that it can pass through many of the water filters that are on the market.
❓ What type of water filter removes iron from water?
👉 This type of water filter is effective at removing iron in both soluble and insoluble forms, but is best for ferrous iron. KDF oxidizing filters are more effective when water has a slower flow rate, giving it more contact time with the media. Most KDF filters can remove between 4 and 6 PPM of iron.
❓ How do you remove ferric iron from well water?
👉 An aeration and filtration system, otherwise known as an air injection oxidation filter, can remove high concentrations of ferric iron from well water. Because this filter also converts ferrous iron into ferric iron, it’s a good option for anyone dealing with both types of iron in their well and water system.
❓ What is ferrous iron and how do I use it?
👉 Crystal-Right ® can be an ideal media for homes getting water from a well. Ferrous iron (Fe +2) is the second type that is dissolved in water, and it cannot be seen – at least not at first. Leave a glass containing what’s often called “clear water iron” out on the counter for a while and watch what happens.
