Physicochemical characterization of UASB sludge with different size distributions
, 2002 Upflow anaerobic sludge blanket (UASB) sludges developed in UASB system are used to treat various wastewaters. Methanogenic microbial consortia in UASB sludges convert organic compounds to methane under anaerobic conditions. Sludge granules are developed

Influence of pulsation on start-up of UASB reactors
Water Science and Technology, 2002 The aim of this work is to study the influence of pulsation on the start-up of lab-scale UASB reactors. Pulsation was produced by an Elastic Membrane Pulsator (EMP). The application of this device in previous works improved the performance of continuous fixed-bed fermentors and reduced the formation of preferential pathways, the retention of gas ...
