In a breakthrough study, researchers have discovered a new way to remove aluminum from wastewater sludge. The team of researchers from the University of Barcelona discovered that hydrolyzed aluminum species can be used to reduce aluminum levels in the sludge. This process involves breaking down aluminum ions in the wastewater into smaller, residual aluminum species that can be removed from the sludge. The research team found that the hydrolyzed aluminum species could be removed from the sludge by a filtration process that allowed for the aluminum to be separated from the water. This process could help reduce aluminum contamination in wastewater sludge and help ensure that it is safe to use for agricultural or other purposes.
