| Summary: | The rapid urbanization in Malaysia has led to the rise in solid waste generation
which eventually increase the generation of leachate in landfill. Apparently, the leachate
in landfill comprises of organic and inorganic substances in which its properties depend
on the landfill age. In the recent years, advanced oxidation process (AOP) has gained
substantial attention in wastewater treatment for pollutant removal. Photocatalysis which
is categorized under AOPs is seen to be a promising technique in eliminating a wide range
of contaminants. Substantial amount of study of photocatalysis in wastewater treatment
has been conducted in laboratory based experimental but has very limited study on
simulation-based experiment. This study aimed to simulate the behavior of the
photocatalytic removal of ammoniacal nitrogen using carbon catalyst through process
simulation. By that, a set of model equations including the hydrodynamic, radiative
transfer equation and kinetics reaction were developed based on the literature. Process
simulation was performed in ANSYS R1 2022 Workbench to simulate the hydrodynamic
field, radiation field and species distribution in the designed annular photoreactor. The
comparison study between the simulation results and existing experimental data shows
that the model developed has a better agreement at higher flow rate of the fluid.
Furthermore, the sensitivity analysis was also conducted to study the effect of initial
concentration of ammoniacal nitrogen on its removal efficiency. It was observed that at
higher concentration of ammoniacal nitrogen, the removal efficiency is decreased. To
conclude, all the objectives were achieved in this project and some recommendations
were provided in order to improve the modeling and simulation study of the
photocatalytic reaction for the application in the future studies. |
