Formatted abstract
The influence of hydraulicretentiontime (HRT) in a submerged hollow fibre membranebioreactor was studied by conducting experiments at four different HRTs (4, 2, 1.3 and 1 h) at room temperature of 25 °C. It was found that a shorter HRT led to ahigher development of trans-membrane pressure. The highest sludge cake and pore-blocking resistances of 4.02 × 1011 m−1 and 0.77 × 1011 m−1 respectively were noted for the shortest HRT (of 1 h) 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.
