==METHOD AND APPARATUS FOR TREATING WASTEWATER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18374378 titled 'METHOD AND APPARATUS FOR TREATING WASTEWATER

==Simplified Explanation==

The method disclosed in the patent application involves treating wastewater containing fluorine by applying a vacuum to a membrane unit, injecting wastewater into the unit, recovering hydrofluoric acid gas, injecting sweep gas, and forming a metal fluoride through a scrubbing process.

* Applying a vacuum to a membrane unit
* Injecting wastewater into the membrane unit
* Recovering hydrofluoric acid gas by evaporating HF in the wastewater
* Moving the evaporated HF to the inner surface through the membrane
* Injecting sweep gas to discharge remaining HF gas on the inner surface
* Forming a metal fluoride by reacting the recovered HF gas with a metal oxide or metal hydroxide

== Potential Applications ==
The technology can be applied in industrial wastewater treatment plants, particularly those dealing with fluorine-containing effluents.

== Problems Solved ==
This method effectively removes fluorine from wastewater, preventing environmental contamination and potential health hazards associated with fluorine exposure.

== Benefits ==
The technology offers a cost-effective and efficient way to treat wastewater containing fluorine, reducing the environmental impact of industrial processes.

== Potential Commercial Applications ==
"Fluorine Removal Technology for Industrial Wastewater Treatment" can be used in various industries such as semiconductor manufacturing, metal processing, and chemical production.

== Possible Prior Art ==
One possible prior art could be the use of chemical precipitation methods for removing fluorine from wastewater. However, this new method offers a more efficient and environmentally friendly approach.

== Unanswered Questions ==

=== How does this technology compare to other fluorine removal methods in terms of cost-effectiveness? ===
The article does not provide a direct comparison with other fluorine removal methods in terms of cost-effectiveness. It would be beneficial to conduct a cost analysis to determine the economic viability of this technology compared to existing methods.

=== What is the scalability of this technology for large-scale industrial applications? ===
The scalability of this technology for large-scale industrial applications is not discussed in the article. Further research and testing may be needed to assess the feasibility of implementing this method on a larger scale.


==Original Abstract Submitted==

A method for treating wastewater containing fluorine is disclosed. The method for treating wastewater includes applying a vacuum to a membrane unit including a membrane having a hollow, injecting wastewater into the membrane unit so that the wastewater contacts an outer surface of the membrane, recovering hydrofluoric acid gas by evaporating hydrofluoric acid (HF) in the wastewater based on a vacuum applied to the inner surface of the membrane and moving the evaporated hydrofluoric acid (HF) to the inner surface through the membrane, injecting sweep gas into the membrane unit to discharge hydrofluoric acid gas remaining on the inner surface of the membrane, and forming a metal fluoride by reacting the recovered hydrofluoric acid gas with a metal oxide or metal hydroxide using a scrubbing process.
