Major Threat in Textile Wastewaters: Tackling Microplastic Pollution with Electrocoagulation Optimized Using Box-Behnken

AI summary · Read the abstract

Researchers optimized an electrocoagulation process for removing polypropylene microplastic fibers from textile wastewater using a Box-Behnken statistical design, achieving 98% removal efficiency at a cost of just $0.31 per cubic meter under optimal pH, current density, and treatment time conditions. With the textile industry being a major source of microplastic fiber pollution, this cost-effective treatment approach offers a scalable solution for intercepting microplastics before they enter waterways and ultimately the food chain.

Advances in electrochemical-based treatment of microplastics in wastewater: removal performance and influencing factors

AI summary · Read the abstract

This review evaluates five electrochemical technologies—electrocoagulation, electrooxidation, electroreduction, bioelectrochemistry, and electrosorption—for removing microplastics from wastewater, finding each offers high efficiency with controllable operating conditions. Because conventional treatment plants miss much of the microplastic entering waterways, scalable electrochemical solutions are urgently needed to prevent these particles from reaching drinking water and marine ecosystems.

Mechanism and Improvement of Electrocoagulation Technology for Removing Microplastics from Wastewater-Current Status and Future Directions

AI summary · Read the abstract

This review analyzed electrocoagulation as a method for removing microplastics from wastewater, finding that hybrid systems combining electrooxidation or membrane filtration achieve over 95% removal efficiency through charge neutralization, sweep flocculation, and oxidative degradation. Efficient wastewater treatment is a critical intervention point for stopping microplastics from reaching aquatic environments and ultimately entering the food chain and drinking water.

Electrochemical degradation of micro/nanoplastics in water: recent results

AI summary · Read the abstract

Researchers reviewed electrochemical oxidation—particularly using boron-doped diamond anodes—as an advanced process capable of degrading micro- and nanoplastics in water with over 90% efficiency under optimized conditions. This technology is important because conventional wastewater treatment plants not only fail to fully remove microplastics but can fragment them into smaller, more bioavailable nanoplastics.
