Iron and Manganese in Water

What does Iron and Manganese Cause?

Iron and manganese can lead to sinks and baths becoming stained and could also affect laundry, especially whites. Iron leaves a brown colour reminiscent of rust while manganese causes a dark staining. The two substances are often found in water together and both are known to clog pipes over time. Also, iron usually emits the smell of hydrogen sulphide, which is as pungent as that of rotten eggs, as well as affecting the taste of water, tea and coffee. Indeed, it can even cause whiskey to go black. Iron and manganese can usually be discovered by adding a sterilising fluid such as Milton which will cause it to oxidise and subsequently discolouring the water.

Before oxidisation, iron and manganese are said to be ‘in solution’, i.e. the water is perfectly clear as it flows from the cold tap. However, it can be oxidised by adding a high-pH substance like Milton or boiling the water. If lime is present in the water, the scale will appear brown.

How to remove iron and manganese

Manganese Water Filter / Iron Water Filter

The best way of removing lime from your water is to purchase and install an iron and manganese water filter system from Nature’s Water Ltd. Our filters remove all traces of iron and manganese from water, as well as eliminating lime. In addition to providing high-quality water filters, we can call to your home or workplace (callouts are free of charge) and install the system for you, assessing the location and workings of the system. You can also arrange a water test if you wish for us to conduct a full analysis. *It is advised to have a full water analysis completed on the water to determine the ideal iron and manganese filter for you.Please complete the Water Analysis Test so we can provide you with the perfect system for your water.Add-Ons:
Adding an undersink reverse osmosis system works hand in glove with your iron and manganese removal system and it is advised to install both together. This not only eradicates iron and manganese from your water, but will also leave your home with crystal clear, bacteria-free water that’s perfectly safe to drink.

Iron and Manganese in Water

Iron and manganese causes major issues in Irish households with staining to our kitchen sinks, staining of our bathroom sanitary ware and clogging up any appliances that use water such as showers. dishwashers and washing machines. Often iron and manganese in high levels, are found to have a lot of limescale also. This combination is lethal on our pipework and appliances. If left untreated, there is a myriad of issues that they will cause. See below a diagram showing the maximum EU levels where Iron, Manganese and Hardness start to cause issues in your home or business. If you have had a recent water test carried out on your water supply simply upload your results below.

Please note some test report show results in mg/l and others in ug/l.

How to treat Iron & Manganese

When eliminating iron, manganese or hardness from your water supply there are a number of different parameters that must be taken into consideration. A detailed water analysis from and accredited laboratory will give us all the details needed to tailor make the prefect water treatment system for your water. These other parameters include Colour, Turbidity, pH, Ammonia, Iron, Manganese and water hardness. Depending on these levels will depend on both the media and head used to treat your water supply. See below some of the medias and heads we use and why these are so important.
Crystal Right:This media is an excellent choice for removing iron, manganese and hardness from your water supply and works best when the iron and manganese are in a dissolved form. Crystal Right uses an ion exchange process which removes iron, manganese, hardness and also reduces ammonia levels. There are two types of Crystal Right medias that can be used and which type will depend on the pH of your water. Where the pH of your water is between 6-7 we would use Crystal right 100 and where your pH level is 7 or above we would use Crystal Right 200.
Filox: Filox is used for treating water where iron, manganese and hydrogen sulphide are present in the water and your water has hardness of less than 80ppm. This is a very heavy media and therefore requires a very strong backwash. Filox does not use ion exchange but instead uses catalytic oxidation meaning you don't have to use salt during the backwash process. In order for Filox to remove iron you must have a pH of above 7 and it must be above 8 for the successful removal of manganese.
Lanxess: Lanxess can be used to remove iron, manganese and limescale where iron and manganese levels are only slightly over the maximum allowed levels. Lanxess media works by ion exchange and works particularly good where limescale levels are high.
Katalox Light: Katalox is a relatively new media and is been used for the treatment of iron, manganese, Hydrogen Sulfide, Arsenic, Radium, Heavy Metals such as lead and Radionuclides. This media is much lighter than other medias meaning it is much easier to backwash and uses less water for each backwash. We have found in cases where iron and manganese levels are extremely high this media works perfect as a pre-treatment system.
Pre-filtration: Where your water test report shows that colour and turidity are over the limits you may also require a pre-filtration unit such as Filter AG or Tubidex. These units are mainly used where the iron or manganese present in the water supply are suspended in the water.
A pre-filter unit will not only eliminate the suspended solids but also prolong the life span of your main filtration media.
Filter Heads: The two main heads used in all of our units are the Clack meter/Volumtric head and Evolve head. These are two of the most economical and robust heads available. Where Ammonia is over the Mac EU value we advise using the Evelove valve along with Crystal Right media as this valve creates chlorine from the brine tank and eliminates Ammonia along with iron, manganese and limescale.
