IRON REMOVAL PLANT IN BANGLADESH

The iron removal system is considered the most effective water treatment system in the sector of industrial water purifiers in Bangladesh. Iron is known as the fourth most abundant element that has been found in the earth’s crust. Then it naturally occurs in water. Though the occurrence of iron in the water is also associated with an industrial origin. CleanTech Engineering LTD is one of the leading companies that has brought iron removal plants in Bangladesh. Our treatment plant can remove iron, manganese, and arsenic from the water. Generally, iron isn’t dangerous for human health or the environment. It only gives a rust color to the water which produces unpleasantness by giving stain to household components or industrial machinery, sanitary facilities, and others. Iron provides a metallic taste to water which does not feel drinkable. An iron removal plant can be used in both home and industry.

Why is the iron removal plant necessary in Bangladesh?  

In the drinking water distribution system, iron is the source of discoloration. Iron removal systems are the common treatment to purify groundwater and produce drinking water for a variety of uses. Through an iron removal plant, the clear water meets the standard of pure drinking water. Due to the settling of hydroxide particles, the water quality can deteriorate in the system of distribution. But it’s important to remove dissolved iron from the water to a large extent. So getting an iron removal plant in Bangladesh is so important.

Problematic elements such as iron, manganese, or sulfur present in the water can make the water thick and sediment as well as result in blocking up the pumps, taps, and filters. A higher level of iron sedimentation can collapse the function of a normal filter or even an entire treatment plant. By reducing the sedimentation of water, an iron removal plant can increase the oxidation process and convert it into rust. Using an ultrafiltration process or non-filtration process, the rust particles available in water can be filtered out very easily. It also minimizes the level of iron and makes it drinkable. The available iron present in water is a matter of concern. The presence of minimal iron in water doesn’t pose any risk to human health. On the other hand, the high presence of iron and other elements in water may lead to unpleasant smells, tastes, and stains in equipment.

The application of Iron Removal Plant

Both houses and companies can use iron treatment plants to purify the water and make it drinkable. So the application of such a plant is-

• Apartments, flats, and homes.
•  Industries.
• Hotels and restaurants.
• Manufacturing companies.
• Hospitals.
• Educational institutes.
• Pharmaceutical industry.
• Food and beverage industry.
• Boiler industry.
• Other industries.

What is the process of iron removal in Bangladesh?

Oxidation filtration is the required process through which the plant removes iron from the water. The process involves oxidizing the soluble form of iron (Fe) and manganese (Mn) to the other soluble form that removes these elements from water. The oxidant not only oxidizes the iron and manganese but also removes iron-related bacteria including any other disease-causing bacteria without any doubt.

The Iron removal system

An accurate iron removal system involves many processes while removing the iron and manganese from the water. The plant uses modern technology to purify water. The system mainly consists of four processes-

Aeration process:

• Through the sturdy sprinkler pipes, the water is pumped into the aeration tank situated on the ground
• Then the water travels to the second chamber from the first chamber through a precisely designed vent located in the baffle wall.
• When the water reaches the third chamber, it establishes maximum air contact, and eventually, the iron content begins to oxidize and suspend iron.
• With required facilitation and expedition, the PH level of feed water can be maintained.
• An effective aeration process depends on the iron level of the water. Normally the aeration tank takes 4 to 8 hours to process the system.

Filtration process:

• The aerated water along with the suspended iron particles have to be sent to the ferrous-free iron removal unit.
• Ferrous-free iron remover contains depth Filtration technology which consists of five layers of unique filter media.
• The filter media oxidizes the leftover dissolved iron content available in the raw water.
• Ferrous-free iron remover can be designed based on the particular flow rate formula.

  Maintenance process:

• After the filtration process, a backwash process takes place. Through the reverse direction, a ferrous free iron removal unit sends water to remove the accumulated iron particles which were suspended earlier.
• The sufficient pressure of water agitates the filter media and helps to take out all the iron particles using the drain port.

  Rinse process:

• After the backwash is completed, the agitate media allows water to pass away through the filter media.

What are the types of iron removal plant systems?

Chemical iron removal: When the groundwater is strongly oxidizing, in the aeration process Chlorine is an element that can be used in the oxidizing process. Even to balance the pH level, different alkaline materials for example- limestone

Biological iron removal system: Instead of the traditional chemical approach, nowadays biological iron removal plants. This process uses certain bacteria to oxidize the level of iron from the raw water. The bacteria that appeared as natural inhabitants oxidized. Here the microorganism properties are necessary to carry out the process. The biological process is more efficient than the chemical one, but if there’s an issue with pH balance and others then the chemical one is the best.

Conclusion

CleanTech Engineering offers total water management all over Bangladesh. We have high-quality and imported water plants which can be used in the field of wastewater management. Our iron removal plant in Bangladesh contains imported parts that use modern technology to purify water. Where iron in water is the most common problem in most of the countries in the World. The industries and home owners in Bangladesh can get the plant whenever they want.
