Monitoring of Microplastics in a Water Reclamation Process with an Improved Recovery Method
Abstract
Microplastics is posing new challenges in wastewater treatment and water reclamation. Water resource reclamation facilities (WRRFs) can be a barrier as well as an avenue for them to enter the environment. In this study, commonly used methods for recovering microplastics from wastewater samples were evaluated, and modifications were made to improve the efficiency of recovering microplastics while preserving their integrity and reducing mass loss. Such method was employed to monitor the occurrence of microplastics in a local WRRF during fall season 2020. Process samples were characterized using optical microscopy and Raman Spectroscopy. Polyester fibers were found to be the most abundant type of microplastics at all stages sampled. An overall amount of 80% of microplastics was removed from wastewater, and the majority reduction took place in primary treatment. Given the potential re-use of wastewater effluent, our results highlight the needs to further reduce microplastics in final effluent.
Microplastics is a rising challenge in water reclamation. Monitoring microplastics in wastewater with a reliable and consistent method is an important step towards eliminating them from wastewater for water reclamation purposes. To this end, the paper proposes a modified method to recover and characterize microplastics from wastewater samples, and includes an analysis of the abundance, characteristics and removal of microplastics in a local water resource reclamation facility. Limitations and future work are also discussed in this study.
