Global plastic pollution is a serious problem. From manufacture to disposal, microplastics appear at every point in the textile life cycle. Numerous case studies demonstrated that wastewater treatment facilities cannot remove the microplastics they produce. The purpose of this study was to evaluate the amount of microplastics that leaks into the canal and adjacent water bodies from a wastewater treatment facility serving the textile industry in Thailand, as well as to discover the differences between the samples taken upstream and downstream. NOAA protected laboratory investigation based findings indicated that 590–601 microplastics particles per cubic meter (particles/m3) flowed into the canal; however, the upstream sample (344–349) had more particles/m3 than the downstream sample (246–252). The industry leaked microplastics on average 172 particles/m3 upstream and 123 particles/m3 downstream. Our research revealed that the wastewater treatment plant’s ability to capture microplastics particles was insufficient. A reliable mechanism to remove microplastics particles from wastewater treatment is required to protect environment, aquatic life, and water quality without interfering with industrial operations. This research emphasizes the Sustainable Development Goals, Responsible Production and Consumption (Goal 12), and Life below Water (Goal 14).

The textile sector is considered as the 3rd largest source of water pollution and land degradation during 2020. 20% 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 (<5 mm) 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 microplas-tic 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-coagu-lation in Thailand textile wastewater plants and adopt the best available technique for microplastic removal.
