Physical and chemical characteristics of microorganisms developed in a modifield anaerobic inclining-baffled reactor treating recycled paper mill effluent / Muhammad Hanif Aslam Anuar

Abstract Pembentukan enapcemar berbutir adalah faktor kejayaan utama untuk modifield anaerobic inclining-baffled (MAI-B) reaktor. Projek ini membincangkan perubahan ciri ciri fizikal dan kimia tentang pembentukan mikroorganisma di dalam untuk modifield anaerobic inclining-baffled (MAI-B) reactor. Reaktor skala kecil ini telah beroperasi pada 37 oC selama 60 hari. Saiz berbutir lebih tinggi daripada 0.33 mm iaitu saiz zarah yang baik. Mikroskop elektron imbasan (SEM) menunjukkan beberapa bakteria mempunyai cocci tidak teratur, rod panjang dan pendek dan bentuk sfera. Inductive coupled plasma mass spectrometer (ICP-MS) analisis menunjukkan keputusan menunjukkan bahawa kalsium, magnesium, besi dan zink mungkin telah memainkan peranan penting dalam pembentukan granular. Untuk electron disperse X-ray (EDAX) analisis menunjukkan karbon, nitrogen, oksigen, aluminium dan silikon adalah unsur-unsur utama yang mempunyai di dalam setiap sampel. X-ray diffraction (XRD), menunjukkan komposisi unsur unsur kimia untuk setiap sampel. Fourier transform infra-red spectroscopy (FTIR) mengesahkan bahawa kumpulan berfungsi bagi permukaan sampel dan kumpulan berfungsi tertinggi bagi sampel ini adalah (C-C, C-O, C-N). Analisis zeta menunjukkan semua sampel adalah negatif cas. _______________________________________________________________________________________________________ The development of granular sludge is the key factor for successful operation of the modifield anaerobic inclining-baffled (MAI-B) reactors. This paper deals with the changes in physical and chemical characteristics of microorganism developed in a modifield anaerobic inclining-baffled (MAI-B) reactors. The bench scale reactor was operated at 37 oC for a period of 60 days.The size of granular is higher than 0.33 mm that is good size particle. Scanning electron microscope (SEM) show some of bacteria have irregular cocci, long and short rod and spherical shape. Inductive coupled plasma mass spectrometer (ICP-MS) analysis show the results indicated that calcium, magnesium, iron and zinc may have played a crucial role in the formation of the aggregates of sludge. For elements analysis by electron disperse X-ray (EDAX), show carbon, nitrogen, oxygen, aluminium and silicon are the major elements that have inside the sample. X-ray diffraction (XRD), show the chemical compositions of elements for each samples. Fourier transform infra-red spectroscopy (FTIR) confirmed the surface functional group of sample and the highest functional group of the sample is (C-C, C-O, C-N). Zeta analysis show all the samples are in negative charge.
