Abstract
Three lab-scale UASB reactors operated at 35 degreesC in an intermittent mo de were subject to different step shocks: hydraulic, organic and feed fat c ontent. The results show that the reactors have good resistance to the appl ied shocks and suggest that a feedless period is beneficial to the performa nce of the reactors, due to stabilisation of accumulated organic matter.
