Filter for removing yellow and turbid manganese sand from well water Filter for removing manganese and iron from groundwater Filter for removing iron from drinking water
The iron and manganese removal filter is mainly used to remove iron and manganese substances in the system to purify water quality; it can also be used to decolor and deodorize water.
Scope of application
It is used in food, beverage, papermaking, brewing industry, the treatment of iron-contained water exceeding the standard, groundwater, well water as drinking water for iron removal, geothermal engineering and swimming pool circulating water needs.
1. Unique multi-filter chamber structure can realize online backwashing (filtering, draining and backwashing at the same time).
2. Electricity saving: the effluent is directly supplied to the pipe network without the need for a secondary water supply system; it has its own backwashing function and does not require another backwashing pump.
3. Water saving: This equipment adopts a "plum-style water distributor" to shorten the distance between the filter layer and the water distribution pipe, which can save a lot of backwash water.
1. Treatment effect:
①. Iron content: ≤0.3mg/L;
②. Manganese content: ≤0.1mg/L;
③. Turbidity of effluent: <3FTU.
2. Water inlet 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.
4. Operating parameters
①. Working method: pressure type;
②. Operation mode: water flow from top to bottom, series (high iron and manganese content) or parallel;
③. Filtration speed: 6-10m/h (when removing iron), 5-8m/h (when removing manganese);
④. Operating cycle: depending on the quality of the raw water, the minimum is not less than 8 hours;
⑤. Backwashing method: water washing, or air-water combined backwashing;
⑥. Backwash time: 10-15min;
⑦. Water consumption for backwashing: 1-3%;
⑧. Backwash intensity: 15-20L/s·m2.
The iron and manganese removal filter consists of an aeration device and a manganese sand filter tank; the low-valent iron and low-valent manganese ions in the water are oxidized into high-valent iron and high-valent manganese ions by oxidation, and then removed by absorption and filtration to reduce iron in the water Manganese content.
1. Process flow
Aeration → contact oxidation → adsorption filtration → backwash
2. working process
According to the water quality, it adopts deep well water residual pressure jet aeration or compressed air aeration. The pipeline is mixed with dissolved oxygen, which is stable and reliable. The aeration method is to increase the dissolved oxygen in the water; the second is to drive off CO2 to increase the PH value of the water, so that the divalent iron is oxidized to precipitate trivalent iron, and then filtered.
②. Contact oxidation
The filter material adopts natural manganese sand filter material, which has a double layer function of catalysis and filtration.
The main component of natural manganese sand is manganese dioxide (Mno2), which is a good catalyst for oxidizing Fe2+ to Fe3+.
When the PH value of iron-bearing groundwater is> 5.5, Fe3+ can be oxidized to Fe3+ by contacting with natural manganese sand. The reaction is as follows:
The Fe3+ generated is immediately hydrolyzed into flocculent iron hydroxide precipitation: Fe3++3OH-=Fe(OH)3↓
③. Adsorption filtration
a. After the manganese sand filter layer, remove the flocs formed by Fe3+ (Fe(OH)3 sediment);
b. The most of the unoxidized Fe2+ catalyzes oxidation and the ion exchange of hydroxyl oxidation to remove iron.
The iron removal mechanism of manganese sand not only relies on its own catalysis, but also gradually forms a layer of iron filter membrane on the surface of the manganese sand filter material as an active filter membrane during filtration, which can play a catalytic role. The newly generated iron oxyhydroxide as the active filter membrane material participates in the new catalytic iron removal process, so the active filter membrane iron removal process is an autocatalytic process.
The principle of manganese removal is the same as that of divalent iron.
The system can adopt manual and automatic control methods. Manganese sand is required to be backwashed regularly to remove impurities such as suspended solids that may be intercepted, and to loosen the manganese sand and cushion. Since the filter is equipped with a backwashing device, no backwashing pump is required.
