FEROLUX F Iron and Manganese Remover – Removes Iron and Manganese (日本 Original)
Due to its special manufacturing method, FEROLUX F is porous and has many gaps. Its iron absorption efficiency is the best among all filter materials.
I. The drawbacks of iron content
Water with high iron content is generally called "red water." Whether for domestic or industrial use, it causes various problems. Iron has a greater impact on various uses than hardness (except for boiler feedwater). Water that appears clear and transparent generally contains 100-200 PPM of salts, mostly sodium (Na) and calcium (Ca) salts, or trace amounts of iron, manganese, and aluminum salts. Salts in water have various harmful effects, and even trace amounts of iron can cause various problems, as iron can endanger harmful substances.
Groundwater typically contains 1 to 10 PPM of ferrous bicarbonate. Therefore, there are certain limits on the iron content of various water types. For example, drinking water must not exceed 0.3 PPM, while some factories strictly limit industrial water to below 0.1 PPM.
High iron content in water has the following disadvantages:
Drinking water may have turbidity, color, or odor.
Household water can stain clothes, tableware, sanitary ware, etc., yellow.
Manufacturing water – can stain, leave spots or blemishes on the product.
Cooling water – contributes to scale formation.
For boiler feedwater – iron can adhere to the surface of ion exchange resins, reducing the resin's effectiveness.
II. General Iron Removal Methods
(1) Air aeration sedimentation filtration method
(2) Air-aeration injection sedimentation method
(3) Ion exchange method
(4) Lime process
(5) Contact filtration method (BIRM, FEROLUX F, FEROLUX M use this method)
The most appropriate method should be selected based on the properties and intended use of the raw water.
In order to save on operating costs, we have gradually adopted the contact filtration method.
(Especially using methods that do not employ oxidation-promoting agents)
III. Functions of the Iron Removal Device
This iron removal device is highly effective at removing dissolved iron from water. Especially effective is the fifth method mentioned above, "contact filtration." Its key point is to oxidize the iron or accelerate its oxidation. The factors affecting the oxidation rate of iron are pH, dissolved oxygen, temperature, and the catalyst. Our company's NCM rapid iron removal device (CLACK iron removal filter) is a state-of-the-art device developed primarily based on the catalytic effect.
These actions are completed within a short time, that is, within minutes. The chemical reaction formula is as follows:
2Fe (HCO3)2 + 1/2 + O2 + H2O –> 2Fe (OH)3 + 4CO2
Groundwater → (Ferrous bicarbonate) → (Air oxidation) → (Catalytic action of iron removal agent) → (Ferric hydroxide) → (Adsorption action of filter media) → Iron removal solution
IV. Special Rapid Iron Removal Agent (FEROLUX F)
The special rapid iron removal agent (FEROLUX F) used in our NCM rapid iron removal device is a 日本 original imported product. Commonly used Zeolite-based iron removal agents (commonly known as iron-manganese sand) are based on clay or silica sand with a chemical coating on the surface. After a short period of use, the surface coating peels off, causing a deterioration in iron removal efficiency. It is necessary to regenerate the chemical or replace the entire agent to restore its effectiveness. However, the FEROLUX F used by our company is completely different in its manufacturing method and raw materials. It is made from TOYOLITE as an adhesive base, combined with special chemicals and sintered. Therefore, the entire granule is essentially the chemical, and even after repeated backwashing, the chemical remains, providing a permanent iron removal effect. Due to its special manufacturing process, FEROLUX F is porous with many pores, making its iron absorption efficiency the highest among various filter media. If dissolved oxygen in the raw water is maintained at 3-5 PPM, Fe++ (ferrous iron) can be completely oxidized and removed by FEROLUX F. FEROLUX F can be said to be the best among various iron removal agents, widely used and well-regarded.
V. Advantages of the NCM type rapid iron and manganese removal filter (CLACK iron and manganese removal machine):
This device directly feeds raw water from a deep well into the iron removal unit. The iron is absorbed by the iron-removing agent, and the effluent is the filtered iron-removed water. Therefore, compared to traditional air-aeration filtration systems, it saves on equipment such as aeration towers, sedimentation tanks, filter pumps, and backwash pumps. Its flow rate is more than three times that of ordinary sand filters. Therefore, the advantages of this device are:
(1) Low equipment cost
(2) Small footprint: Ideal for small waterworks, large hotels, hospitals, schools, etc.
(3) Simple operation and management
Furthermore, because the iron removal agent used is the original imported 日本 FEROLUX F, it has the following advantages:
(4) No increase in salts: This device does not require the addition of chemicals, so it does not add useless salts to the treated water.
(5) Low operating and maintenance costs: FEROLUX F does not require chemical regeneration and can be used indefinitely. It is manufactured using high-temperature processing, making it less prone to breakage and loss, with minimal waste. Only 10% needs to be replenished annually.
(6) Can also remove manganese: General iron removal methods are difficult to remove manganese, but this device can easily remove manganese from water by adding chlorine gas.
Remark:
If the raw water has a high manganese content, please use FEROLUX M. Please consult with our engineers for the treatment method.
Due to its unique manufacturing process, FEROLUX F is a porous material with numerous pores, making its iron absorption efficiency the highest among all filter media. Technical Explanation
FEROLUX Comparison table with manganese sand
| FEROLUX | manganese sand |
| The parent material is a special type of clay, formed through multiple sintering processes. It is porous and has strong adsorption capacity, allowing the medicine to penetrate its interior. Therefore, the entire particle is a medicinal component, maintaining its efficacy for a long time. | The parent material is ordinary quartz sand, and the reagent only coats the surface of the sand, making it easy to peel off during backwashing. |
| With a specific gravity of only 0.7, only a small amount of water is needed to loosen the filter bed during backwashing, achieving a thorough backwashing effect and effectively reducing the amount of backwash water required. | With a specific gravity of approximately 1.1 (or 1.4), a large volume of water is required to move the filter bed during backwashing, resulting in wasted backwash water. |
| FEROLUX F is specifically designed to remove iron from water; simply inject a small amount of compressed air at the inlet.
FEROLUX M is specifically designed to remove iron and manganese from water. A small amount of sodium hypochlorite needs to be added at the inlet to promote the oxidation effect. |
Whether used for iron or manganese removal, sodium hypochlorite must be injected at the inlet to achieve the desired effect. |
| It has excellent iron and manganese removal effects, does not require regeneration and never deteriorates, saving the trouble of regeneration of ordinary manganese sand or the need for regular replacement, and can save a lot of maintenance costs. | Manganese sand typically loses its effectiveness after about 5-8 months of use, requiring regeneration with compounds such as permanganate (which is expensive) or complete replacement, resulting in significant financial waste. |
