摘要：Various factors affecting granulation process as gleaned from the literature are operation time (to),organic loading rate (O), upflow velocity (Vup), polymer loading (PL), acceleration (g), specific density of granule (g ) and specific density of water ( w ), temperature, pH, nutrients and trace metals, quantity of seed sludge,exocellular polymer, reactor configurations, its geometry and characteristics of wastewaters etc. A mathematicalapproach was used to model the granule size variation in upflow anaerobic sludge blanket (UASB) reactor underdifferent operating conditions using Buckingham- theorem. Obtained power multiplier function of granule size (Dg)can be used to predict the granule size variations in UASB reactor.
