Combined extraction centrifuge

Magnesium is an important industrial metal, widely used in alloys, fertilizers and medicine. However, wastewater discharge of magnesium may have some impact on the environment. Therefore, the development of efficient magnesium removal technology is particularly necessary. The combined extraction centrifugal extractor provides a feasible technical path for magnesium extraction.

Environmental properties of magnesium

Magnesium is found in water mainly in the form of magnesium ions (Mg² +). The excessive presence of magnesium may affect the ecological balance of water and lead to the deterioration of water quality. Therefore, the removal of wastewater containing magnesium is an important task to achieve water quality safety.

Separation principle of combined extraction centrifugal extractor

The combined extraction centrifugal extractor realizes the efficient separation of magnesium ions in wastewater through the centrifugal force generated by high-speed rotation. The specific steps include:

1. Waste water feeding: the waste water containing magnesium is injected into the equipment.

2. Centrifugal separation: In the process of high-speed rotation, magnesium ions settle due to relatively large density.

3. Precipitation collection: The settled magnesium is collected through the system for subsequent treatment.

Optimized extraction conditions

Key conditions for improving magnesium extraction efficiency include:

1. Centrifugal speed: between 3000-6000 rpm is recommended to improve the sedimentation speed of magnesium.

2. Processing time: Appropriate extension of processing time can usually improve the extraction rate of magnesium, and the recommended time is 15-25 minutes.

3. pH adjustment: The separation effect of magnesium is better under neutral to slightly acidic conditions.

Magnesium follow-up treatment and resource recovery

The extracted magnesium precipitates can be recovered by roasting, chemical treatment and other methods. The reuse of magnesium can not only reduce environmental pollution, but also provide important raw materials for related industries.

The technology of magnesium extraction from wastewater by combined extraction centrifugal extractor provides a new idea for water pollution control. With the development of technology, its market potential will gradually appear.
