Iron And Manganese Water Treatment
the Problem of iron & 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.

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 Head
The two main heads used in all of our units are the Clack meter/Volumetric 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 Evolve valve along with Crystal Right media as this valve creates chlorine from the brine tank and eliminates Ammonia along with iron, manganese and limescale.
