Synthetic silver nanoparticles do not appear to hinder textile wastewater treatment using aerobic granular sludge, according to a study by iBB published in Ecotoxicology and Environmental Safety.
Over 246 days, reactors with and without nanoparticles showed similar dye and organic load removal efficiency.
The nanoparticle-fed system improved granule settling and degraded a stubborn aromatic amine.
