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 to discharge remaining gas, and forming metal fluoride through a scrubbing process.
- The method involves applying a vacuum to a membrane unit with a hollow membrane.
- Wastewater is injected into the membrane unit to contact the outer surface of the membrane.
- Hydrofluoric acid gas is recovered by evaporating HF in the wastewater based on the vacuum applied to the inner surface of the membrane.
- The evaporated HF is moved to the inner surface through the membrane.
- Sweep gas is injected to discharge remaining HF gas on the inner surface of the membrane.
- Metal fluoride is formed by reacting the recovered HF gas with a metal oxide or metal hydroxide using a scrubbing process.
Potential Applications
This technology can be applied in industrial wastewater treatment plants, particularly those dealing with fluoride contamination.
Problems Solved
This method effectively removes fluorine from wastewater, preventing environmental contamination and health hazards associated with fluoride exposure.
Benefits

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.
