Moving Bed Sequencing Batch Reactor: Optimization Of Operational Parameters For Nitrogen And 4-Chlorophenol Removal.
PhD thesis, Perpustakaan Hamzah Sendut.
Abstract
Moving bed sequencing batch reactor (MBSBR) which incorporates both
suspended-growth and attached-growth biomasses in a single reactor has been widely
used in wastewater treatment plants. Nevertheless, information on the treatment of
nitrogen containing wastewater via MBSBR is still scarce. Thus, more attention from
researchers to explore the potential of using MBSBR in biological nitrogen removal
is needed. This study aimed to optimize the use of polyurethane (PU) foam cubes as
a support media and to apply the optimum aeration strategy during the REACT phase
in the MBSBR for the enhancement of nitrogen removal in low COOIN ratio
wastewater. In addition, the effect of 4-chlorophenol (4-CP) on the simultaneous 4-
CP and nitrogen removal in the MBSBR was also investigated.
The MBSBR was initially packed with PU foam cubes of various sizes to
determine the effect of support media size on nitrogen removal. Subsequently, the
aeration strategy during the REACT phase was converted from continuous to
intermittent aeration and the performance of both aeration strategies in removing
nitrogen was compared. The attached-growth biomass from the PU foam cubes was
also dried and later added into the MBSBR to assess the feasibility to be utilized as
an alternative solid carbon source in enhancing the nitrogen removal.
