Evaluation of the Presence of Microplastics in Wastewater Treatment Plants: Development and Verification of Strategies for Their Quantification and Removal in Aqueous Streams
Summary
Researchers evaluated microplastic presence in wastewater treatment plants and developed a pilot capture system capable of detecting, quantifying, and removing microplastic particles from water. The study found that conventional treatment processes are insufficient for complete microplastic removal, highlighting the need for dedicated technologies to address this gap in water treatment infrastructure.
Water is an essential resource whose quality is threatened by emerging pollutants, including microplastics (MP), whose persistence, bioaccumulation capacity and ecotoxic potential pose a growing risk to ecosystems and human health. Wastewater treatment plants (WWTPs) have been identified as one of the main sources of these pollutants, as conventional treatments are insufficient to remove them completely. In response to this problem and with the aim of finding more efficient and sustainable solutions, a study has been carried out at WWTP with a pilot MP capture plant capable of detecting, quantifying and removing these particles from different wastewater sources with high precision and sustainability. This proposal represents a significant advance in the mitigation of invisible pollution, contributing to the protection of the environment and public health, achieving an efficiency of over 80% in the removal of plastic particles. This system not only addresses the challenge of environmental protection but also represents an unavoidable commitment to a healthier, more equitable, and sustainable development model for current and future generations, directly contributing to strategic action to advance the fulfillment of several Sustainable Development Goals (SDGs) promoted by the UN (SDG 3, SDG 6, SDG 12, SDG 14 and SDG 15).
