Technical principle of

The working principle of the manganese sand filter combines the two processes of physical filtration and chemical oxidation, mainly for the treatment of water bodies containing iron, manganese, and other heavy metal ions, to achieve the purpose of purifying water quality. The specific working principle is as follows:
1. Physical filtration: The manganese sand filter is filled with specially treated manganese sand filter material, which has a certain pore structure, which can intercept the suspended matter in the water, sand, and other large particle impurities, and play a preliminary physical filtration role.
2. Chemical oxidation: The principal ingredient in manganese sand, manganese dioxide (MnO2), has a natural oxidation property that catalyzes the oxidation of iron (Fe² +) and Mn² + ions in water, transforming them into compounds of the water-insoluble iron (Fe³ +) and Mn⁴ +. This process is manifested as follows:
• Oxidation reaction of iron: 4Fe² + O₂ + 10H₂O → 4Fe(OH)₃ + 8H +
• Oxidation reaction of manganese: 2Mn² + O₂ + 4H₂O → 2MnO₂ + 8H +
3. Adsorption and precipitation: Oxidized iron and manganese ions form insoluble precipitates (such as Fe(OH)₃ and MnO₂), which are caught by the physical retention and adsorption of the filter material surface when the water flows through the manganese sand filter, and thus removed from the water.
4. Biocatalysis: In some cases, a layer of biofilm may be formed in the manganese sand filter, in which microorganisms (such as iron bacteria) can accelerate the oxidation process of iron and manganese ions, further improving the treatment efficiency.
5. Backwashing and regeneration: With the filtration process, impurities will gradually accumulate on the surface of the manganese sand filter layer, requiring regular backwashing operations. When backwashing, the water flow direction is reversed to remove the accumulated impurities between the filter material and restore the filtration capacity of the filter material. For manganese sand, it has a certain self-regeneration ability, because the MnO2 on its surface will be constantly renewed during the oxidation process to maintain its activity.

Frequently Asked Questions

Q: How is there suspended matter in the water from the manganese sand filter?
A: The presence of suspended matter in the discharge water may be because the filtration rate is too fast, resulting in manganese sand can not effectively intercept impurities. Adjusting the water flow speed to ensure that it matches the filter's design rate can solve this problem.

Q: How to determine whether the manganese sand in the manganese sand filter needs to be replaced?
A: With the increase of use time, the surface of manganese sand may be covered by iron mud, affecting its catalytic effect. Usually by observing the color change of manganese sand to determine whether it needs to be replaced, if the color becomes darker, it may need to be replaced or regenerated.

Q: Can manganese sand filters be used to soften water quality?
A: The manganese sand filter is mainly for the removal of iron and manganese, and has limited effect on the softening of water (removal of calcium and magnesium ions). If water softening is required, consider using specialized water-softening equipment.

Q: What should I pay attention to when backwashing the manganese sand filter?
A: Backwashing is a key step in restoring manganese sand filtration capacity. When performing backwashing, it is necessary to ensure that the backwashing water speed and time are appropriate to remove trapped pollutants without flushing out too much manganese sand.

Q: Is the manganese sand filter affected by the influent pH?
A: Yes, the pH value of the inlet water affects the efficiency of the manganese sand filter. Oxidation removal of iron and manganese is usually more effective under neutral or slightly alkaline conditions. If the water is too acidic, the pH may need to be adjusted for better treatment.
