Samsung patents wastewater system that uses UV light to break down PFAS
Samsung describes a machine that cleans water containing persistent chemical pollutants known as PFAS. The system mixes in chemicals to adjust acidity and remove oxygen before using ultraviolet light to break down the harmful substances.
In the filing’s own words
A wastewater treatment apparatus includes a wastewater storage assembly configured to store wastewater including per- and polyfluoroalkyl substances (PFAS), a reducing agent mixer configured to add and mix a reducing agent into the wastewater, a pH adjuster configured to add a pH adjusting agent to the wastewater and adjust a pH, a dissolved oxygen remover configured to remove dissolved oxygen from the wastewater, and a reactor configured to radiate ultraviolet rays to the wastewater and decompose the PFAS in the wastewater, and a final treated water storage assembly configured to store the wastewater in which the PFAS are decomposed.
What exactly they claim (claim 1)
1. A wastewater treatment apparatus comprising: a wastewater storage assembly configured to store wastewater comprising per- and polyfluoroalkyl substances (PFAS); a reducing agent mixer configured to introduce and mix a reducing agent into the wastewater; a pH adjuster configured to introduce a pH adjusting agent into the wastewater to adjust a pH of the wastewater; a dissolved oxygen remover configured to remove dissolved oxygen from the wastewater; a reactor configured to radiate ultraviolet rays to the wastewater and decompose the PFAS in the wastewater; and a final treated water storage assembly configured to store the wastewater in which the PFAS have been decomposed.
