In order to study the start-up of anaerobic fluidised bed (AFBS) treating ice-cream factory wastewater, several start-up protocols were tested applying different aiders while the organic load was increased stepwise. These aiders were: biological preconditioning of the wastewater in a continuous flow-stirred tank reactor at constant hydraulic retention time; chemical preconditioning of the wastewater with the supplementation of CaCl2 and a mixture of detergents. The protocols enhanced the AFBS start-up performance. Each start-up protocol increased the maximum efficiency of COD removal for the range of organic loadings applied by comparison with the control system, although the best substrate removal efficiency was not associated with the best methane yield. |
