RO Iron Removal Filter

The purpose of a RO (Reverse Osmosis) iron removal filter is to filter out iron and other associated contaminants from water. It is a specialised part or stage of a RO water treatment system. Although RO membranes are good at removing dissolved particles, some forms of iron may not be removed by them. In order to improve the RO system's ability to remove iron, a second iron removal filter is frequently added.

An RO iron removal filter operates as follows:

1. Pre-Filtration: To get rid of bigger particles, sediments, and debris, water typically goes through pre-filtration stages before it enters the RO iron removal filter. In order to safeguard the iron removal filter and avoid blockage or damage, this is crucial.

2. Filter for Iron Removal: This filter is made specifically to target and remove iron from water. Depending on the particular type of filter being used, it uses a variety of ways to do this. Following are examples of typical iron removal filters:

• Catalytic carbon filters: These filters use a particular kind of catalyst-impregnated activated carbon. The filter media then absorbs the ferric iron that is created when the ferrous iron is oxidised. Both dissolved and colloidal iron can be efficiently removed using the catalytic carbon filter.
• Birm Filter: Birm is a granular manganese dioxide filter material. Through a procedure known as catalytic oxidation, the iron is changed into a solid form that is simple to collect and filter out. Birm filters work well to get rid of dissolved iron.
• Greensand Filter: Made up of zeolite and manganese dioxide, greensand is a filter media. It uses catalytic oxidation, like Birm, to change the iron into a solid form that can be filtered. Both dissolved and colloidal iron can be effectively removed using greensand filters.

3. Post-Treatment: To further enhance the water's quality after it has been through the iron removal filter, post-treatment procedures may be used. To make sure the water satisfies the required criteria, extra filtration stages, pH adjustment, disinfection, or the addition of corrosion inhibitors may be used.

4. Reverse Osmosis: The water moves on to the reverse osmosis stage after the iron has been eliminated or greatly reduced by the iron removal filter. Here, it is pushed through a semi-permeable membrane that filters out salts, dissolved particles, and other contaminants, including any lingering iron residues. 

The total efficiency of iron removal is increased by adding an iron removal filter to a RO system. As a result, the RO system's water is guaranteed to be free of iron and other related pollutants, supplying high-quality water for a variety of uses. To get the best results, it's crucial to select the right iron removal filter based on the kind and amount of iron present in the water supply.

FAQ

1. What is a RO Iron Removal Filter?

Ans - A reverse osmosis system called a RO iron Removal Filter (RORF) is made primarily to remove ferrous iron particles from water. It aids in lowering the amount of iron, which can lead to water discolouration, stains on fixtures, a bad taste, and unpleasant odours.

2. What advantages do RO Iron Removal Filters offer?

Ans - RO Iron Removal Filter will enhance the purity and flavour of water while lowering the risk of corrosion and the buildup of scale in fixtures and appliances like water heaters. Additionally, it helps shield water-using equipment from long-term harm.

3. What distinguishes a RO Iron Removal Filter from a water softener?

Ans - RO Iron Removal Filter employs a membrane to filter out iron particles, whereas a water softener uses a salt-based method to remove calcium and magnesium. A RO Iron Removal Filter is primarily made to remove iron from water, but a water softener also aids in reducing the accumulation of soap scum.

4. What is iron removal from water so crucial?

Ans - In drinking water, iron particles can result in a number of cosmetic and health issues. It can damage plumbing and result in water that tastes and smells bad. Additionally, it can leave stains on clothing, furniture, and appliances. 

5. How frequently should I swap out my RO Iron Removal Filter?

Ans - Every two to three years, you should change your RO Iron Removal Filter. However, because they can differ based on the brand and type of filter, please see the owner's manual for details.
