Manganese sand filter for Iron and Manganesium removal birm media

Manganese sand filter material is made of domestic high-quality manganese sand ore, which has dense particles, high mechanical strength, strong chemical activity, is not easy to break, is insoluble in water, and is natural manganese sand. It is processed into sand through water washing, polishing, crushing, drying, magnetic separation, screening, dust removal, etc. The processed manganese sand is then proportioned according to a certain grade.

We are a 20 years experienced global water filter supplier and YiHang factory will have more competitive prices for our customers. Our professional sales team will be happy to assist you. Please feel free to contact us!

Specification

Product Parameters：

Manganese sand is an efficient and economical media for reducing dissolved iron and manganese compounds in raw water. It can be used in gravity-fed or pressurized water treatment systems.

Manganese sand filter media acts as an insoluble catalyst, enhancing the reaction between dissolved oxygen and iron compounds. In groundwater, dissolved iron is usually in the ferrous carbonate state and cannot be filtered due to excess free carbon dioxide. Manganese sand filter media acts as a catalyst between oxygen and soluble iron compounds, enhancing the oxidation reaction of Fe²⁺ to Fe³⁺ and producing iron hydroxide, which precipitates and is easily filtered.

The physical properties of manganese sand make it an excellent filter media, and the precipitate can be easily removed by back washing. Manganese sand filter media is not consumed in the iron removal operation, which gives it a huge economic advantage over many other iron removal methods.

Principle of natural manganese sand filtration

1. Drinking water standards of the People's Republic of China

Iron (mg/L) 0.3

Manganese (mg/L) 0.1

2. Principle of iron and manganese removal

Water with too high iron and manganese content is generally oxidized into insoluble trivalent iron or tetravalent manganese compounds by using a catalyst (such as manganese sand) to remove and purify the dissolved divalent iron or divalent manganese.

4Fe2++O2+10H2O 4Fe(OH)3+8H

2Mn2++O2+2H2O 2MnO2+4H+

3. The main process flow of iron and manganese removal at present

Raw water containing iron and manganese--aeration device--intermediate water pump--oxidation reaction--iron and manganese removal filter--iron and manganese removal water

2. Influent requirements:

①. Iron content: ≤20mg/L;

②. Manganese content: ≤3mg/L;

③. Influent turbidity: <20FTU;

④. Alkalinity: ≤2mg/L;

⑤. pH value: >6.0 (when removing iron), >7.5 (when removing manganese).

3. Working environment parameters

①. Working temperature: 5-60℃ (special temperature can be customized);

②. Working pressure: ≤0.6MPa

The appearance is black brown particles, the main component is manganese dioxide (Mn02), the content is between 30% and 65%. It has good iron and manganese removal properties, and is an essential product for iron and manganese removal and yellow removal of drinking water in groundwater and industrial water.Hydrogen Sulfide should be removed prior to contact with Manganese sand filter media.Natural manganese sand as the filter material to effectively removes iron and manganese ions.

Manganese sand filter media usually be used for groundwater treatment filter; quality totally can meet the national standards for drinking water. Manganese sand filter common specifications are 0.4-0.6mm, 0.6-1.2mm. Special specifications can be processed according to user’s demand.

The common specification of manganese sand filter material are

0.4mm-0.6mm,0.6-1.2mm,1-2mm,2-4mm,4-8mm,8-16mm,16-32mm.

Special specification can be processed separately accoring to user needs.

Packaging and shipping

Application:

The birm media used in Iron and manganese filter system can help to remove the extra iron and manganese ions to guard people healthy and guarantee industrial production smoothly running.

The manganese sand filter suitable for iron and manganese removal filtration devices (filter tanks, filter pools) for domestic water, with good water filtration effect

Mainly used for pre-treatment of mineral water, purified water, ionized water production lines to remove iron and manganese, as well as pre-treatment of geothermal and swimming pool projects to remove iron and manganese.
