Iron removal filters – Process of iron removal filter system

Overview

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.

Iron removal filter systems play a key role to remove iron content and gives us fresh water.
