Iron & Manganese Removal Filters
After Limescale, Iron & Manganese are the most common problems dealt with by homeowners in well water. At CWS, we strive to supply you with the most cost effective solutions for Iron and Manganese removal. Iron in water is clearly distinguishable, it appears as a brown/red colour and can clog pipework and water pumps. At low levels water softeners are the most simple method for the removal of Iron & Manganese. At higher levels it may require media such as Birm, Filox, Crystal Rite, Lanxess or Eco Mix. In extreme cases the best treatment may be chlorination.
High Iron in water:
Iron is a brown/red rusty colour and causes:
Brown/red staining on sanitary ware.
Staining on laundry, especially whites.
Brown deposits in pipework.
High Manganese in water:
Manganese is a metal and high concentrates in water can result in:
Drinking water having an unpleasant bitter taste.
Deposits on food during cooking.
Stains on sanitary ware.
Discolouration of laundry.
Deposits on plumbing fittings and cooking utensils.
Iron & Manganese Removal Systems
CWS offer a range of filter systems to eliminate Iron and Manganese from well water. Sometimes it may require more than one water system to filter high levels of Iron and/or Manganese. Factors such as the water pH can influence the type of filter media required. Below are just some of our water treatment media;
Automatic back washing filter system using a Birm media. Birm is an efficient and economical method of removing dissolved iron and manganese compounds from well water as it does not require salt or chemicals to regenerate. It acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the iron/manganese compounds. When using Birm for iron removal, it is necessary that the water contains no hydrogen sulphide or oil, and organic matter can not exceed 5 ppm. Also the dissolved oxygen content must be at least 15% of the iron content, and have a pH level of 7 or higher. For manganese removal the above also applies but the minimum pH level needs to be 8.0.
Crystal Rite Iron & Manganese Unit
Automatic back-washing filter using crystal rite media which regenerates using tablet salt. Crystal rite provides superior removal of iron, manganese & hardness while raising pH levels of acidic water at the same time. Crystal rite crystals provide better filtration and are thoroughly cleaned by back-washing faster than ordinary resins without loss of product. Crystal Rite is available in two types;
Crystal Right 100 is used where the raw water pH is between 6.0 and 7.0. (if the pH is lower than 6.0 then conventional pH correction will also be needed.)
Crystal Right 200 is used where the raw water pH is 7.0 or above, its advantage in this situation is a higher capacity.
Iron & Manganese Filters
- How can I remove Iron from my water?
If you have a very high level of iron oxide or manganese it will need to be treated to make it safe to use. How you treat it is usually specified based on water test results so a water test must be carried out. Once the results are back we can then specify the media need to remove all traces from the water and how often the filter needs to clean itself.
- How does an Iron & Manganese filter work?
The size of the filter is specified based on the amount of iron oxide or manganese which is in the water. The size is very important in enabling the water to come into contact with the media for a specific amount of time. If the water rushes through the filter too quickly then it will not have time to react with the media which in turn will not remove the iron or manganese.
- How can I filter bad smells or taste from water?
As long as the actual cause is filtered before as an example iron in the water which is removed with an iron filter can sometimes leave a bad taste or horrid smell. This can then be removed using a carbon filter which is the same size as a sediment filter but instead of catching sediment it will treat the water and the carbon reacts with the bad odours and tastes.
