Abstract:

The influence of hydraulic retention time (HRT) in a submerged hollow fibre membrane bioreactor was studied by conducting experiments at four different HRTs (4, 2, 1.3 and 1h) at room temperature of 25°C. It was found that a shorter HRT led to a higher development of trans-membrane pressure. The highest sludge cake and pore-blocking resistances of 4.02×10 11m -1 and 0.77×10 11m -1 respectively were noted for the shortest HRT (of 1h) application. UV and fluorescence spectroscopy analyses showed that the nature of organics in the biomass and sludge cakes were different. The organic fraction analysis by liquid chromatography with organic carbon detector (LC-OCD) showed a significant amount of biopolymers and a lower amount of humics for longer HRT. © 2011 Elsevier B.V.
