Compartmental profile of Modified Anaerobic Baffled Reactor (MABR) during Recycled Paper Mill Effluent (RPME) treatment- physico-chemical characteristics of anaerobic sludge / Chong Yu Nong

Abstract Rawatan anaerobik adalah kaedah yang paling biasa digunakan dalam merawat efluen perindustrian, yang dalam laporan ini, rawatan anaerobik digunakan untuk merawat efluen kilang kertas kitar semula (RPME). Efluen kilang minyak kelapa sawit (POME) digunakan dalam reaktor baffled baffled (MABR) yang diubahsuai dengan RPME segar. MABR adalah makan harian dengan RPME sehingga fasa berterusan bermula. Semasa fasa berterusan, pengambilan organik yang rendah sebanyak 0.2 g COD / L telah digunakan selama 20 hari. Enam kaedah telah digunakan untuk menganalisis sampel enapcemar dari setiap petak: mikroskop elektron imbasan (SEM), Inframerah Transformasi Fourier (FTIR), X-ray difraksi (XRD), spektrometri fotoelektron X-ray (XPS), analisis termogravimetrik (TGA) dan Brunauer-Emmett-Teller (BET). Keputusan menunjukkan bahawa granul anaerobik terdapat dalam sampel yang kebanyakannya terdiri daripada unsur karbon (C). Kehadiran logam berat telah dikesan juga dalam enapcemar anaerobik melalui analisis XRD. Analisis EDS menunjukkan bahawa karbon terdiri daripada kebanyakan komponen bukan organik yang dikesan dalam enapcemar anaerobik. Kawasan permukaan BET berkisar antara 3.7610 m2 / g dan 10.8416 m2 / g, di mana kawasan permukaan berkurangan dari petak 1 hingga petak 5. _______________________________________________________________________________________________________ Anaerobic treatment is the most common method used in treating industrial effluent, which in this report, anaerobic treatment is used to treat recycled paper mill effluent (RPME). Palm oil mill effluent (POME) was used inoculated in modified anaerobic baffled reactor (MABR) together with fresh RPME. MABR was daily batch-fed with RPME until continuous phase started. During continuous phase, low organic loading of 0.2 g COD/L was applied for 20 days. Six methods were applied in analyzing the sludge sample from each compartment: scanning electron microscopy (SEM), Fourier-Transform Infrared (FTIR), X-ray diffraction (XRD), X-ray photoelectron spectrometry (XPS), thermogravimetric analysis (TGA) and Brunauer–Emmett–Teller (BET). The results show that anaerobic granules are present in the samples in which are mostly made up of the element carbon (C). Presence of heavy metals were detected as well in the anaerobic sludge through XRD analysis. EDS analysis shows that carbon made up most of the inorganic components detected in the anaerobic sludge. The BET surface area range between 3.7610 m2/g and 10.8416 m2/g, in which the surface area decreases from compartment 1 to compartment 5.
