Description
Summary:<b>Abstrack</b><p align=\"justify\">Upflow Anaerobic Hybrid Reactor, consist of a Suspended Growth Reactor and a Fixed Film Reactor, was created to separate the area of acidogcnesa and methanogenesa. In the Fixed Film Reactor (FFR), cells were immobilised at the surface of supporting media (bamboo). Immobilised cells have a different characteristic and ability in using substrate from suspended cells. Diluted mollases was used as sintetic substrate, representing wastewater with high organic concentration. Chemical Oxygen Demand (COD) concentrations in the inlet were adjusted at 40, 60, and 90 WI, and hidrolic detention time were varied at 24, 30, 48, and 72 hours (organic loading 13.76 - 97.60 g/I.day). The result shows that detention time variations make an significant effect on quantity of immobilised cells, and inlet COD variations (and organic loading variations) influence the structures of bioftlm. Inlet COD concentration 40 g/l and detention time 30 hours is the optimum condition for FFR, where specific utilization rate (k) is 2.55 g COD/g VSS.day and COD removal in FFR is 52.63%. Volatile Suspended Solids (VSS), Total Colonies, COD, thickness of bioftlm, and pictures made from Scanning Electron Microscopy (SEM) are used in analysing the result.
