ClearIdentification, removal of microplastics and surfactants from laundry wastewater using electrocoagulation method
Laundry wastewater from a 2 kg synthetic fabric load released up to 114,300 microfibers per wash, and an electrocoagulation treatment removed roughly 98% of those fibers along with surfactants and organic load in about 25 minutes at a cost of US$0.53 per cubic meter. The results highlight both how significant laundry is as a microplastic source and that electrocoagulation is a cost-effective option for treating it before wastewater reaches natural waterways.
