1、 Equipment name: full automatic iron and manganese removal well water treatment equipment

2、 Specification and model: hdnct-8000l

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

1、Iron exists in the state of Fe2+ in water, and Fe2+ ion is very easy to pollute ion exchange resin, making resin toxic and reducing exchange capacity. After being heated, it is very easy to generate iron scale on the heating surface, affecting heat transfer and corrosion equipment. Groundwater containing excess iron, or well water, has peculiar smell in water.The iron and manganese removal filter USES the REDOX reaction of MnO2 contained in natural manganese sand with Fe2+ to make Fe2+.After Fe3+ is changed and Fe (OH) 3 is precipitated, it is removed with the backwash function of the filter.

2. After aeration of iron bearing groundwater, it is filtered by the natural superior manganese sand series filter material of our company. The oxidation reaction of iron in the water can be completed rapidly in the filter layer, and the iron is retained in the filter layer at the same time, so as to complete the whole iron removal process.

3. After aeration of manganese bearing groundwater, it is filtered by a series of natural high-grade manganese sand filter media, which makes the hydroxides of high manganese gradually attach to the surface of the filter media, so that the bivalent manganese in the water is oxidized to high manganese to be removed.

4. The pump pumps the groundwater into the aeration device.

5. The aeration device uses the residual pressure of the well pump to fully mix the oxygen in the air with the well water containing iron and manganese ions.

6. The aerated well water passes through the filter layer in the filter:

① Physical adsorption and retention of filter material,

② Autocatalytic oxidation of iron oxide film on the surface of filter material,

③ Biological oxidation of iron and manganese bacteria in the filter.

Through the joint action of the above three forms, iron and manganese ions in the well water are solidified in the filter layer to complete the filtration process.

7. The filtered clear water enters the water supply system.

8. After the iron and manganese trapped in the filter reaches the designed capacity, the back cleaning system will automatically start, and the oxide of the iron and manganese trapped will be discharged from the filter through the shunt pipe. 　

5. Source water characteristics:

1. Characteristics of well water with excessive iron content:

◇ clear well water turns light yellow after several hours to one day in the pool.

◇ A few days later, the bottom of the pool precipitated yellow iron mud, and the wall of the pool was dyed yellow.

◇ after boiling, the water turns yellowish, and the higher the iron content, the deeper the yellow.

◇ floating oil film on water surface.

◇ The well water just pumped has obvious smell of iron.

2. Characteristics of well water with excessive manganese content:

◇ The dyeing ability of manganese is weak, and the dyeing effect of manganese cannot be seen when iron exceeds the standard.

◇ when the manganese alone exceeds the standard, the pool wall and the ground where the water is used will be dyed black and there will be delamination. .

◇ The laundry will darken the color of the clothes.

Food, beverage, textile, papermaking, brewing, aquaculture, agriculture, and other water containing excessive iron.

◇ the well water is from clear to yellow, rather than the yellow water extracted directly from the well.

◇ Well water is fresh water, not salt water. (salt water is not suitable for this equipment, it can be detected by a small amount of taste.)

◇ the pump is a deep well pump (the pump placed in the water), not a self-priming pump (placed on the ground). If it is a multi-stage pump placed on the ground or a pump with a specified lift of more than 30 meters, it is OK.

◇ purchase large-scale equipment, customers need to provide well water quality report.
