Performance of Electrocoagulation Process for Microplastic Fibre Removal from Laundry Wastewater
AI summary Read the abstract
This study tested electrocoagulation as a method to remove microplastic fibers from laundry wastewater, using both synthetic microplastics and real laundry effluent. The process demonstrated effective removal through flocculation and deposition mechanisms, offering a potential treatment solution for textile-derived microplastic emissions.
Laundry wastewater contains not only detergent but also contains fabric fibres and threads. Microplastic fibres have been discovered as a potential source of microplastic fibres in synthetic clothing washed in the environment. To reduce microplastic concentration in wastewater, many approaches have been developed. Electrocoagulation is one of them. Using both synthetic microplastics and laundry wastewater samples, this study examined the performance of electrocoagulation methods to remove microplastics. The flocculation and deposition mechanisms remove microplastic fibre. This research was set up by using a reactor with a volume of 1 L, 60 V of voltage and 60 minutes of contact time. Electrical current of 5A and 10A was applied to remove microplastic fibres during electrocoagulation (EC). The removal efficiency of polyester fibre was 55-68 per cent for 60 minutes with a current of 5A and 42-85 per cent for 60 minutes with a current of 10A. Polyamide fibre removal efficiency in 60 minutes is 53 per cent to 74 per cent at 5A current and 57 per cent to 72 per cent at 10A current. According to this study, it can be concluded that EC can remove microplastic fibre from laundry effluent.

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.
Removal of Microfiber from Laundry Wastewater Using the Electrocoagulation Method
AI summary Read the abstract
Researchers investigated microfiber release from laundry wastewater and found a reference load of 2.5 L of synthetic textiles released approximately 92,700-114,300 synthetic microfibers. Electrocoagulation treatment at neutral pH, 25-minute operating time, and 300 A/m² current density achieved 97.9% microfiber removal efficiency at a treatment cost of US$0.53/m³.
Electro-coagulation technique using iron [Fe] and aluminium [Al] for microplastics removal from fashion industry wastewater, Thailand
AI summary Read the abstract
Laboratory tests showed that electrocoagulation — running electrical current through iron and aluminum electrodes — can remove microplastics from textile industry wastewater in Thailand with high efficiency. Because conventional wastewater treatment plants were not designed to capture particles as small as microplastics, electrochemical methods like this represent a promising upgrade to reduce the millions of microplastic particles released daily from textile factories.
