Remediation technology of microfibers from washing machine effuents
AI summary Read the abstract
Researchers developed a treatment method combining Fenton oxidation and electro-sorption to remove polyester microfibers from washing machine wastewater. Washing synthetic clothing is a major source of microplastic fiber pollution, and effective wastewater treatment at the machine level could significantly reduce this pathway into aquatic environments.
This research report presents a novel and sustainable method for removing microfibers, a type of microplastic, from washing machine sewage. The study focuses on polyester microfibers, which are released into the environment during the washing of synthetic clothing and have negative impacts on aquatic organisms and ecosystems. The proposed method combines Fenton reaction pretreatment and electro-sorption to effectively target the ester bonds in polyester microfibers and increase their electrical distribution homogeneity. Under optimized experimental conditions, including a Fe(NO3)3 concentration of 100 ppm, H2O2 concentration of 1.96 M, temperature of 25°C, pretreatment time of 30 minutes, electrode of nickel foam for cathode and carbon rod for anode, NaCl concentration of 3.5 g/L, appli...[ Read more ]

Identification, removal of microplastics and surfactants from laundry wastewater using electrocoagulation method
AI summary Read the abstract
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.
