Opis:: Membrane separation technologies equipped with ceramic membranes have shown good operational results, high robustness and reliability. In this study, a combination of Moving Bed Biofilm Reactor (MBBR) & Membrane Bioreactor (MBR) (pilot scale) was investigated for fouling control optimisation. The system was operated with flat-sheet microfiltration (MF) ceramic membranes. Because of the attached biofilm in the MBBR, it could work stably and effectively with different loading rates, which reduces the load on the membrane surface. Influences of sludge recirculation and flux on the transmembrane pressure (TMP) value and thus impact on fouling development were investigated. Intensive aeration, backwash as well as the implementation of NaOCl were used as physical and chemical cleaning, respectively. The chemical cleaning efficiency reaches up to 70% and could be increased after further research. After the determination of optimal operational conditions, the normalised permeability value (PN) was effectively maintained with a slight TMP increase.

Opis:: In present study, the synergistic separation of Cr(VI) has been investigated from synthetic acidic solution containing Cr(VI), Co(II) and Ni(II) by fl at sheet supported liquid membrane (FSSLM) technique using triisooctylamine (TIOA) and tri-n-butyl phosphate (TBP) as carriers. The main goal of the study was based in the exploring of the synergistic effect of TBP on selective extraction of Cr(VI) in presence of Co(II) and Ni(II) ions. The various parameters related with membrane and aqueous solution properties were studied to identify the optimum extraction and stripping conditions of the Cr(VI) through FSSLM. In the optimum conditions, initial mass flux (J0) and separation factors (β_Cr/Co and β_Cr/Ni) were obtained as 1.49 x 10-05 (kg/m2.s), 382.2 and 725.3 respectively from aqueous H₂SO₄ media through Celgard 2500 (Celgard Inc., USA) polymer support. As a result, the considerable synergistic infl uence on selective transport of Cr(VI) through FSSLM using TIOA and TBP as carriers has been identified.
