Zinc is an important metal, widely used in alloy manufacturing and electroplating industries. However, the discharge of zinc-containing wastewater has a serious impact on the environment. Therefore, the development of efficient zinc removal technology is particularly important. The automatic combined extraction centrifugal extractor provides a possible solution for this.

Environmental properties of zinc

Zinc is found in water mainly in the form of zinc ions (Zn² +). Excessive discharge of zinc will cause water pollution and affect the survival of aquatic organisms. Long-term exposure to high concentrations of zinc can be potentially harmful to human health, so removing zinc from wastewater has become an important task for environmental protection.

Working mechanism of combined extraction centrifugal extractor

The automatic combined extraction centrifugal extractor uses centrifugal force to separate zinc from wastewater, the specific steps are as follows:

1. Feed operation: Feed the wastewater containing zinc into the equipment.

2. Centrifugal separation: During high-speed rotation, zinc ions settle to the bottom of the equipment due to their high density.

3. Collection and discharge: The precipitated zinc is collected regularly to facilitate subsequent treatment.

Optimized extraction process

Key parameters to improve zinc extraction efficiency include:

1. Centrifugal speed: Appropriate increase of speed can accelerate zinc sedimentation, the recommended range is 4000-7000 rpm.

2. Processing time: Extending the processing time can improve the extraction rate of zinc, usually 20-30 minutes.

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