Advanced Fluorine Treatment Facilities
Our Advanced Fluorine Treatment Facilities uses a crystallization method using calcium-based apatite to effectively remove fluorine. Furthermore, it is more compact compared to existing methods, investment and operational costs are also lower. Used crystallizing materials can also be recycled.
Principle of Crystallization Method
First of all, fluorine wastewater which has been primarily treated at a manufacturing facility is sent to this reactor. It is then mixed with the phosphoric acid calcium agent that stimulate the crystallization of fluorine.
The fluorine in the wastewater adheres to the surface of the crystallizing materials in the reactor and is then removed.
After the fluorine has been removed, the treated water is discharged from the upper outlet of the reactor. Part of the treated water is recycled back into the treatment tank to enhance fluidity of the crystallizing materials.
Features
- The structure of the equipment is simple and compact.
- Both initial and running costs are also lower.
- Used crystallizing materials can be recycled as industrial raw materials, so it contributes to zero emissions of factories.
- Low maintenance
- Space saving. It has a vertical reactor structure, so it can be installed at confined places
