Application of Inorganic Coagulant and Carbon-Based Adsorbent Combination for Microplastic Removal from Greywater

Bodnár, IldikóAl Balushi , Khadija2025-06-132025-06-132025-06-04https://hdl.handle.net/2437/391728This study evaluates the removal of Polyethylene Terephthalate (PET) microplastics from synthetic greywater using four coagulation–filtration systems: GAC alone, FeCl₃+GAC, CPE+GAC, and FeCl₃+CPE+GAC. Among them, FeCl₃+GAC showed the highest removal efficiency for turbidity (97.5%), TOC (98.0%), COD (96.0%), and BOD₅ (94.0%). Although the dual coagulant system (FeCl₃+CPE) had comparable results, it did not outperform FeCl₃ alone. CPE alone achieved full PET retention, likely due to electrostatic and bridging interactions. Zeta potential shifts confirmed effective particle destabilization. Fluorescence microscopy verified PET removal. The treated effluent met FAO/WHO standards for restricted irrigation.79enPET microplasticsgreywaterferric chlorideApplication of Inorganic Coagulant and Carbon-Based Adsorbent Combination for Microplastic Removal from GreywaterMűszaki tudományokHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
