Abstract

In this research, hydrodynamic behaviour in a novel fluidized bed reactor (FBR) was studied by using a residence time distribution (RTD) experiment. The RTD experimental result showed that the liquid flow pattern closed to plug flow behaviour. Moreover, the novel FBR was performed under low hydraulic retention time (HRT) operation (without internal recirculation), and its performance should be further investigated. There are two experimental approaches for wastewater treatment application. The first approach, a novel FBR, was performed for treating nitrate with a denitrification process at COD : NO3- - N of 1 : 1, 2 : 1, 3 : 1, 5 : 1 and 10 : 1. The highest nitrate removal efficiency was obtained at 99 ± 1%, with a ratio of COD:NO3- - N of 3 : 1. In the second approach, a novel FBR was evaluated in low strength anaerobic wastewater treatment. The novel FBR achieved 86 ± 6% of COD removal efficiency at an organic loading rate (OLR) of 5.6 g COD L-1d-1.
