tuyển nổi
Definition
- Noun (Technical/Industrial Process):
- Flotation: A separation process used in mineral processing and wastewater treatment where small air bubbles are introduced into a mixture. Hydrophobic (water-repelling) particles attach to the bubbles and rise to the surface, forming a froth that can be removed, while hydrophilic (water-attracting) particles remain in the liquid.
Usage Examples
- Noun:
- Phương pháp tuyển nổi thường được dùng để tách quặng đồng. (The flotation method is often used to separate copper ore.)
- Nhà máy xử lý nước thải sử dụng tuyển nổi để loại bỏ dầu mỡ. (The wastewater treatment plant uses flotation to remove oils and greases.)
Advanced Usage
- "Tuyển nổi khí hòa tan" (DAF): Dissolved Air Flotation. A specific type where air is dissolved under pressure and then released to form microbubbles.
- DAF là công nghệ tuyển nổi hiệu quả cao. (DAF is a highly efficient flotation technology.)
