Reply to comment by northbathroom 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
I think these are supposed to be used at the point of waste generation rather than a waste processing facility.
Plus, if you know the binding capacity of the filter and the concentration of dye, you could simply use multiple filters and swap them after a set volume. Once the used filter is removed, you can probably leave them in the sun until it’s ready to be disposed. A low cost makes this pretty viable.
