Introdução aos reactores UASB / EGSB

, 1994
[Excerto] O UASB (acrónimo de Upflow Anaerobic Sludge Blanket) é um reactor de fluxo ascendente possuindo uma zona de decantação interna e um separador gás-sólido-líquido na sua parte superior. O sistema não possui meio de enchimento como suporte de biomassa.

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 ...
