    Application of mixture of coagulants in greywater treatment
    Akpomie, Frederick; Bodnár, Ildikó; DE--Műszaki Kar
    Greywater treatment and reuse are vital for sustainable water management, reducing strain on fresh water sources and pollution in water bodies. Hybrid coagulants are promising for water treatment, but their efficiency in greywater treatment remains understudied. A bench-scale study evaluated hybrid coagulation-filtration in treating sythentic bathroom greywater. The hybrid approach, using ferric chloride and lime, proved most effective, optimizing colloids removal and achieving high turbidity removal with a neutral pH. The study also tested real bathroom greywater, finding similar results though variations existed due to different sources. The hybrid coagulation-filtration process consistently met water reuse standards, outperforming single coagulant methods, highlighting its efficacy for decentralized greywater treatment.

    Investigation of zeta potential measurement and the utilization of MPT-2 Titrator unit in greywater treatment
    Kakish, Essa; Bodnár, Ildikó; DE--Műszaki Kar
    Amid escalating water scarcity, the exploration of innovative solutions becomes imperative. 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.
