This research delves into the potential of domestic greywater, a substantial component of household wastewater, constituting a promising resource. Focused on repurposing bathroom greywater (BGW), the study aims to optimize treatment processes through coagulation-flocculation, utilizing the MPT-2 titrator unit. The unit's role is pivotal in determining precise coagulant doses necessary to achieve the isoelectric point, while continuously monitoring the effect of chemical dosing, a crucial aspect in effective treatment. Comparative analyses involve the examination of two coagulants, Iron(III) chloride and Aluminium Sulphate, on synthetic and real BGW samples. The study explores differences between synthetic and real BGW compositions, elucidating diverse characteristics such as pH, turbidity, biological oxygen demand (BOD5), and Total Organic Carbon (TOC) values. Additionally, variations in certain samples necessitate higher coagulant concentrations for achieving optimal treatment conditions. Conclusively, the research underscores the significance of the MPT-2 unit in streamlining the determination of precise coagulant doses. This automated tool facilitates rapid preliminary analyses based on raw BGW quality, vital for devising tailored treatment strategies catering to the complexities of varied greywater compositions.68enbathroom greywatertreatment and reusecoagulation-flocculationZetasizer Nano Z deviceMPT-2 TitratorDEENK Témalista::Engineering SciencesHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
