Arsenic is an element widely used in industry and agriculture, but its wastewater discharge poses a serious threat to the environment, especially in terms of water quality and biological health. Therefore, the development of efficient removal of arsenic technology is particularly important. The combined extraction centrifugal extractor provides an effective solution for the treatment of arsenic-containing wastewater.

Environmental characteristics of arsenic

Arsenic is mainly found in water in the form of arsenate (AsO₄³⁻ or AsO₃³⁻). Its accumulation in water bodies can be toxic to aquatic life, and long-term exposure can cause serious health problems. Therefore, removing arsenic from wastewater is an important task to achieve water quality safety.

Separation source of combined extraction centrifugal extractor

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

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

2. Centrifugal treatment: In the process of high-speed rotation, arsenic ions are separated and settled due to their density.

3. Precipitation collection: The settled arsenic is collected through the system to facilitate subsequent treatment.

Optimized extraction conditions

Key conditions for improving the efficiency of arsenic extraction include:

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

2. Processing time: Extending the processing time usually improves the extraction rate of arsenic, and the recommended time is 15-30 minutes.

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

Arsenic follow-up treatment and resource recovery

The arsenic precipitates after extraction can be recovered by incineration or chemical treatment, and the reuse of arsenic helps to reduce environmental pollution and promote sustainable development.

The application of combined extraction centrifugal extractor to extract arsenic from arsenic-containing wastewater provides an efficient technical means for water pollution control. With the continuous progress of technology, its market potential will gradually emerge.
