Electro-coagulation technique using iron [Fe] and aluminium [Al] for microplastics removal from fashion industry wastewater, Thailand
Summary
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.
The textile sector is considered as the 3rd largest source of water pollution and land degradation during 2020. of the world’s water pollution is linked with textile production and utilisation. Textile washing releases 14 million tons of microplastics, according to European Environmental Agency estimates. Wastewater Treatment Plant [WWTP] has declared everyday normal releases of more than 4 million MP particles because of its tiny size (<5mm) and low thickness (<1.2 g/cm3). Electrochemistry for the removal of tinny pollutants is recognised as an efficient treatment mechanism. The main aim of this research paper is to identify the efficiency of electro-coagulation technology using Fe and Al as anode and cathode in microplastic removal from Thailand’s textile industries. Results show the maximum 100% microplastic removal efficiency with pH 10 at a current density of 30 A/m2 within 60 minutes of the current supply. This paper helps to understand the role of electro-coagulation in Thailand textile wastewater plants and adopt the best available technique for microplastic removal.
