Abstract
ObjectiveThis study aims to assess the concentration and removal efficiency of microplastics (MPs) at a major wastewater treatment plant in Jordan, a region with limited data on MP pollution.MethodsA field-based experimental study was conducted. Grab samples of 14 L were collected from both influent and effluent streams on a single sampling day. Wet sieving was used to isolate MPs in the 38-1000 µm range, followed by wet peroxide oxidation and optical microscopy for particle quantification and morphological classification.ResultsThe influent contained an average of 62.6 MPs/L, while the effluent had 23.8 MPs/L, resulting in an overall MP removal efficiency of 62%. Fibers and fragments were the most prevalent types in the effluent, indicating partial resistance to the treatment process.ConclusionThe results underscore the presence of residual MPs in treated wastewater and suggest a need for more robust filtration technologies and plastic management strategies to reduce environmental MP release.
期刊介绍：
Science Progress has for over 100 years been a highly regarded review publication in science, technology and medicine. Its objective is to excite the readers'' interest in areas with which they may not be fully familiar but which could facilitate their interest, or even activity, in a cognate field.
