Why can manganese sand filter material have the effect of removing iron and manganese from groundwat

The mechanism of manganese sand filter material is basically the same as that of iron removal by contact oxidation. After the aeration of manganese-containing groundwater, it is filtered by the manganese sand filter layer, so that the hydroxide compounds of ** manganese are gradually attached to the surface of the filter material to form a manganese active filter membrane, form a manganese active filter membrane, and form a manganese active filter membrane. In addition, according to the rule that sol particles preferentially adsorb particles with the same or similar composition as them, manganese sand containing mno2 can adsorb Mn2+ in water well.

Shandong Linyi Xinxin manganese sand plant. Natural manganese sand is a strong oxidizing agent, which can oxidize the stock iron in water. There are two principles for the use of natural manganese dioxide sand to remove iron:

One is the effect of the so-called active filter membrane, and there is a strong oxidation on the surface of manganese sand. The other is the anti-iron catalysis of manganese sand itself. The ferric iron in the water is catalyzed into ferric iron, and then the ferric iron is attached to the surface of the manganese sand particles for thousands of weeks to achieve the purpose of iron removal.

Natural manganese dioxide can oxidize the divalent iron in the water to trivalent iron to precipitate and remove, so that the water is clean, and the manganese dioxide is oxidized by the dissolved oxygen in the water into heptavalent manganese oxide. Heptavalent manganese then oxidizes the ferric iron in the water to ferric iron.

Linyi Xinxin Manganese Sand Factory, the natural manganese sand filter material produced has a good effect on iron and manganese removal. The quality is stable.

Because natural manganese sand filter media has this effect. Ask the next floor, Shandong Linyi Xinxin manganese sand plant.

Dear, hello I am glad to Nianzhou to answer for you: the easiest way to remove iron and manganese from groundwater A, pro: 1

Groundwater is usually filtered to remove iron and manganese. In the process of groundwater aeration, solvent oxygen is used as an oxidant, and manganese sand valence iron is used for catalysis, the purpose is to carry out ion exchange, adsorption and then oxidation between manganese sand filter material and low-valent iron and low-valent manganese to achieve the purpose of removing iron and manganese. It can also be filtered with an iron-manganese removal equipment filter.

2.The contact oxidation method is adopted. After adding air and water and other mixtures to the inlet of the water pump of Shenwu well with a jet, the ferric iron in the water is oxidized into ferric iron, which is filtered and adsorbed by the filter material (manganese sand or quartz sand with a high cavity of the cavity), and the ferric iron is intercepted in the filter layer, so as to achieve the purpose of removing iron and manganese.

Summary. Hello, the easiest way to remove iron manganese from groundwater.

Methods for removing iron and manganese from groundwater: adding alkali to adjust pH value, strong oxidant oxidation, ion exchange method, ozone oxidation, magnetic separation method, etc. The development of the theory and technology of iron and manganese removal from groundwater has generally gone through three stages in China: natural oxidation, aeration contact oxidation, and biological manganese removal.

1. Overview of automatic iron and manganese removal filter.

Many towns and industrial and mining enterprises in China rely on groundwater as their water source. However, in many areas, groundwater contains excessive iron, and its content is generally in the range of 2-16mq l. "Automatic iron and manganese filter" overcomes various problems caused by human operation, backwashing, etc., and better plays the characteristics of fully automatic work, so it has the incomparable superiority of other iron removal devices, and the iron content of the treated groundwater meets the national GB5749-85 drinking water quality standard.

In addition to iron and manganese in water, it must be aerated to oxidize divalent iron and divalent manganese with oxygen in the air to generate Fe(OH)3, Mno2. The use of one or more stages of manganese sand filter filtration, can meet the treatment requirements, the effluent iron content, manganese content, in line with the national drinking water standards.

2. Iron content of effluent: in line with the national GB5749-85 drinking water quality standard.

3. Surface load: 8-9m3 h·m2

4. Flushing intensity: 14-16L s·m2

5. Flushing duration: 4-6mim (adjustable).

6. Inlet water pressure:

7. Filter material: fine manganese sand particle size for iron and manganese removal.

8. Working temperature: 5 40 (special temperature can be customized).

3. The unique advantages of urban automatic iron and manganese removal filter.

1. The automatic iron and manganese removal filter is fully automatic. From the water inlet, oxygen, water distribution, filtration, backwashing, and effluent processes, it is combined into an integrated new iron removal device. All of them can be automatically adjusted according to the operating requirements.

2. There is no need to be equipped with suction device, air compressor, backwash pump or water tower. It not only saves the project investment, but also brings a lot of convenience to the project operation management, maintenance and other work.

3. The special manganese sand filter material with high iron removal efficiency is used, which can ensure the requirements of water quality and quantity after use.

4. If the high and low water level electrical control system is set up in the clear water pool and connected to the opening and closing system of the deep well water pump, then the complete system can meet the requirements of the unmanned automatic water purification treatment system.

Fourth, the scope of application of automatic iron and manganese removal filter.

The iron and manganese removal filters are divided into two series: one is suitable for the iron removal treatment system with an iron content of 8 mg l in groundwater. The other is suitable for the iron removal treatment system of groundwater iron content 》8mg l- 16mg l.

The two kinds of iron and manganese removal filters are suitable for small and medium-sized towns, rural water supply, industrial and mining enterprises, industrial water, softening, desalination process and other treatment systems that use groundwater as the water supply source.

First of all, please choose pure natural manganese sand filter material, which is the key and the first step, Shandong Linyi Xinxin manganese sand plant.

The manganese sand filter material has the most ideal grading ratio of water treatment filter media, so that it has the largest specific surface area, the strongest sewage interception capacity, the largest oxidation catalytic effect and the smallest backwash loss rate per unit volume.

The appearance of manganese sand filter material is rough and brown or light gray, and it is often used in the iron and manganese removal filtration device of domestic drinking water, and the water filtration effect is very good.

Natural manganese sand iron removal is a contact catalytic iron removal process, which is suitable for iron removal with an iron content of less than 20mg l in groundwater. The ** manganese contained in natural manganese sand can oxidize the divalent iron in the water into trivalent iron, and at the same time form an "active filter membrane" with catalytic effect on the surface, which further improves the iron removal effect. After the molten iron is aerated and filtered only once by natural manganese sand, it can complete the whole iron removal process, which is often used in drinking water iron removal, manganese removal filtration device, groundwater iron and manganese removal to purify water quality.

As a high-quality material for the treatment of groundwater, manganese sand filter material is reasonable, easy to operate, convenient for construction, stable and efficient, and the service cycle can generally reach 5 years, which can efficiently remove iron, manganese, arsenic and other substances in the water, and meet the national drinking water standard.

The appearance of manganese sand filter material is rough and spherical oval, the surface is reddish-brown or black-brown, and manganese ore mainly contains manganese oxide and manganese dioxide. It can be used for both iron removal in groundwater and manganese removal in groundwater. And the treated water quality can meet the industry standard of the water industry.

Manganese sand filter material is mainly used to reduce the total content of iron, manganese and manganese in the water, according to China's drinking water hygiene standards for its iron content, manganese content, drinking water with high iron and manganese content for a long time will seriously affect health; For products in textile printing and dyeing, food and other industries, spots will be generated; Strong corrosive ability to production equipment.

Iron was used in underground (well) water in the state of Fe2+, and the water has a different color and odor, which pollutes the ion exchange resin and reduces the exchange capacity, and forms iron scale after a long time, which affects heat transfer and can corrode equipment.

The mnO2 in the manganese sand filter material undergoes a redox reaction with Fe2+, which turns Fe2+ into Fe3+ and generates Fe(OH)3 precipitate, so that the backwashing function of the manganese sand filter can be used to achieve the purpose of removal and purification.

Characteristics of manganese sand: manganese sand has high mechanical strength, good chemical strength stability, long service life, stable quality, and good performance of iron and manganese removal.

In addition to iron and manganese sand filter material, most of the water is used in groundwater and water with iron and manganese content exceeding the standard, and the strength of iron removal depends on the level of manganese dioxide content, and the more manganese content, the better. However, the hardness of the manganese sand filter material is related to the service life of the manganese sand and the entire treatment process.

Treatment of groundwater, simple process, easy operation, small footprint, low project cost, long-term stability, service cycle of more than 5 years, easy to manage, without adding any chemical agents can achieve the purpose of removing iron, manganese, arsenic and other harmful substances in the water.
