Siti Fitriana Alang Ahmat Modelling simultaneous nitritation and p-nitrophenol removal using aerobic granular biomass in a continuous airlift reactor / Siti Fitriana Alang Ahmat Kuantan, Pahang : UMP, 2015 xv, 40 p. : ill. (some col.) ; 30 cm. + 1 CD-ROM Faculty of Chemical & Natural Resources Engineering Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang - 2015 Bibliography : p. 31-33 A mathematical biofilm model was developed with a dual-biomass kinetic including Haldane formalism to describe simultaneous nitritation and p-nitrophenol (PNP) removal in aerobic granular biomass operating in continuous airlift reactor. The model was validated with a set of experimental result previously reported in the literature. Then, the model was explored further to study the influence of pH, initial concentration of PNP in the influent, temperature of the operating system, and the influent loading rate for total ammonia nitrogen (TAN) and p-nitrophenol. The result showed that the maximum capacity of the reactor to treat simultaneous nitritation and PNP were 46.15 gN L-1d-1 and 288.5 mg PNP L-1d-1, respectively. Studying the effect of pH value in simultaneous nitritation and PNP removal, it showed that the range for optimum operation is between 7.3 and 8.3. While, the maximum advisable operating temperature is at 55°C. Higher operating temperature would result to a poor removal performance. In conclusion, simultaneous nitritation and PNP removal could be achieved in a single rector by using granular biomass.
