Iron removal filters – Process of iron removal filter system
Iron removal filter:
The Iron Removal Filters system is advanced equipment used to remove the iron content in the water by using low-pressure drops.
Iron removal filter systems:
Iron removal filter systems play a crucial role in water treatment systems. Iron is one of the elements majorly available in the earth’s crust. So removing iron from water is a very common problem in many countries. It is the earth’s crust, so it is soluble in water too. It is naturally soluble in water in the form of ferrous iron or ferric iron. Another reason for the iron element in water is that industries like mining, iron, and steel industry.
In order to remove iron from water, dissolved iron need to convert into a suspended form. Very effective removal of iron can be done in two processes. They are:
- Aeration process
- Filteration process.
Aeration process:
The aeration process is again divided into the online aeration process and the offline aeration process.
Online aeration process:
Borewell water is pumped into the aeration tank. This tank was divided into three equal-sized chambers. The first chamber is designed as perforated sturdy sprinkle pipes where raw water is allowed through it. Then water can be travel into the other two chambers through different vents located at different baffle walls. Thus produced a zigzag motion in water.
When the water reaches the third chamber, it naturally contacts air, so the dissolved iron gets oxidized and converted into suspended iron. If the feed water PH range is acidic, add a measured dose of a suitable oxidizing agent removal process.
The aeration tank surface is not viable in terms of space constraints. The same needs to be constructed under the ground. In the underground aeration tank, aeration is handled by using a blower and diffuser. To remove underneath sludge precipitated by using sludge pump. Aeration tank’s efficiency may differ upon volumes, dimensions, and designs.
Offline aeration process:
The bore water is allowed into the aeration tank, a single chamber by specially designed sprinkles in this offline aeration process. Then the water needs to stagnate for up to 4 to 8 hours in the aeration tank for a very effective aeration process. If the feed water PH range is acidic, add a measured dose of a suitable oxidizing agent removal process.
Filteration process:
Aeration water contains all the suspended iron particles and sent into ferrous free iron removal system with very depth filtration technology. Ferrous-free iron removal contains five layers of distinctive filter media that oxidize the dissolved leftover iron and filters the suspended solids, suspended iron, odor taste, bad color by VOID creations. These ferrous-free iron removals are designed according to the exact flow rate formula.
Maintenance process:
Backwash process:
After the successful filtration process, the accumulated iron suspended particles need to be removed from the ferrous free unit by sending the water towards the reverse direction. In the reverse direction, the water with enough pressure will distrub the filter media and remove all the iron particles using the drain port.
Rinse process:
After successful completion of the backwash, the agitated media will be allowed to settle by passing the water through filter media.

Conclusion:
Iron removal filter systems play a key role to remove iron content and gives us fresh water.
What are iron removal filters? Different types of iron removal system processes
What are iron removal filters?
The Iron Removal Filters are manufactured mainly to remove the excess iron content in the water by using minimum pressure drop.
Working principle of iron removal filters:
Most iron removal filters work on the principle of oxidizing the iron (oxidation). So it can convert from a ferrous or dissolved to a ferric or undissolved state. When the iron is converted to a ferric state completely, it is scuttled on a filter bed.
For very low iron content in the water, the Filter contains Manganese Zeolite. The iron is oxidized to insoluble or undissolved hydrated oxides, removed by the Zeolite bed’s mechanical filtering action.
Different types of iron removal system processes:
Iron is one of the abundant elements available in the earth’s crust. So groundwater contains iron. It does not affect both human beings and the environment, but it changes the color of water, odor smell which may feel uncomfortable while drinking water. So it is important to remove iron from the water. The following are two types to remove iron from water. They are:
- Chemical iron removal systems.
- Biological iron removal system.
Chemical iron removal systems:
Iron is removed from water by creating an environment called oxidizing, but it should be very strong. It can be successfully created by using the aeration process. Add oxidants like chlorine, or else you can raise the PH range of water by using alkaline materials like limestone. Under these conditions, soluble ferrous iron is converted to ferric iron, forming a precipitate of insoluble iron hydroxide (Fe(OH)3) that filtration can remove. For many decades this process is adopted to treat groundwater throughout the world.
Biological iron removal systems:
Biological iron removal systems are among the best alternatives to Chemical iron removal systems for the past ten years. Microbiologists have discovered that certain bacteria have a strong capacity to oxidize and immobilize iron. bacteria play a key role in the whole process as natural inhabitants in the environment.
So microorganisms are necessary to start the process, and they are carried with the groundwater onto the filters. Then iron oxidizers require aeration to stimulate their growth, grows on the surface area of the filter bed like a slimy orange mat. So if it is in this bacterial activity zone, then the iron removal process appears to occur. Biological iron removal systems also conclude to everyone that the biological enchantment process is very efficient compared to the chemical iron removal technology.
Is iron in water causes any effect to human by consuming it?
Not at all. Iron in water does not affect humans and the environment too. It brings the only unpleasantness of an aesthetic and organoleptic nature. Iron also gives rust color to water sometimes. It also gives a metallic taste to water which seems difficult to drink.
