1、 The hazards of iron and manganese in water and water requirements:

1. The hazards of iron in water

Iron in groundwater often exists in the form of divalent iron. Due to the high solubility of divalent iron in water, the iron containing groundwater just extracted from the aquifer is still clear and transparent. However, once it comes into contact with air, the divalent iron in the water is oxidized by oxygen in the air, generating insoluble trivalent iron hydroxides that precipitate from the water. Therefore, although iron in groundwater has no impact on human health, it cannot exceed a certain level. When the iron content in water exceeds 0.3mg/l, the water becomes turbid, and when it exceeds 1mg/l, the water has an iron fishy smell. Especially when water contains excessive iron, rust spots can form on washed clothes; Yellow brown rust stains can appear on clean sanitary appliances, as well as on walls and floors that come into contact with water, causing inconvenience in daily life applications.Harbin Iron and Manganese Removal EquipmentHarbin groundwater treatment equipment, Harbin iron and manganese removal equipment

2. The hazards of manganese in water

Manganese in groundwater often exists in the form of divalent manganese. The rate of dissolution and oxidation of divalent manganese in water is very slow, so it generally does not make the water quickly turbid. However, after precipitation, it can increase the color of the water, and its coloring ability is several times higher than iron. It has a strong ability to pollute clothing and sanitary ware. When the manganese content exceeds 0.3mg/l, it can cause the water to produce an odor.

When the iron and manganese content in water is too high, it not only brings inconvenience to daily life, but also brings many problems to industrial production. For example, iron and manganese are one of the components that generate scale in boiler water. In cooling water, iron adheres to the heating tube wall, which can reduce the heat transfer coefficient of the tube wall and even block the cooling water pipe. In addition, the continuous growth of iron manganese bacteria can accelerate the corrosion of metal pipelines.

Reaction equation:

4MnO2+3O2=2Mn2O7

Mn2O7+6Fe2++3H2O=2MnO2+6Fe3++6OH-

Fe3++3OH-=Fe(OH)3↓

In order to avoid the harm of iron and manganese in water to production and life, there are certain restrictions on the concentration of iron and manganese in water.

For drinking water, iron should be less than 0.3mg/L and manganese should be less than 0.1mg/L. Brewing water requires an iron content of less than 0.1mg/L.

The working principle of the iron and manganese removal device:
lavender waterwater treatment equipmentThe company's iron and manganese removal equipment uses oxidation methods to oxidize low valent iron ions and low valent manganese ions in water into high valent iron ions and high valent manganese ions, which are then removed through adsorption filtration to achieve the goal of reducing the iron and manganese content in water. The filter material is made of refined quartz sand or manganese sand.

Many underground waters contain fluoride and have concentrations exceeding national standards. If not treated, they cannot be used as drinking water for daily life because long-term consumption of water with high fluoride content can cause fluorosis, affecting physical health. Mild cases can lead to blackening of teeth, discoloration, enamel loss, and early tooth loss, while severe cases can cause bone hardening and even skeletal deformities.

Therefore, in order to ensure the physical and mental health of the people and protect the environment, our company has carefully developed and produced a defluorination device, which can make the fluoride content of the treated water meet China's drinking water standards, that is, less than 1mg/l.Harbin iron and manganese removal equipment, Harbin groundwater treatment equipment, Harbin iron and manganese removal equipment
