title: Effects of organic, hydraulic and fat shocks on the performance of UASB reactors with intermittent operation.
abstract: Three lab-scale UASB reactors operated at 35 degrees C in an intermittent mode were subject to different step shocks: hydraulic, organic and feed fat content. The results show that the reactors have good resistance to the applied shocks and suggest that a feedless period is beneficial to the performance of the reactors, due to stabilisation of accumulated organic matter.
