Reply to comment by YouAreGenuinelyDumb in Scientists have shown how toxic dyes can be filtered out of wastewater using the method and material developed by the group. The procedure uses sunlight as a catalyst and doesn’t involve any pressure or heat. It can remove 80 percent of dye pollutants in wastewater. by Wagamaga
Just keep doing that 80% until it is diluted enough or filtered enough. 80% of 20% is 16%, so you have 4% left, then you have 0.8% left ezpz
Idk if this works it is most likely wrong
