Description: Molasses wastewater was treated anaerobically using anupflow anaerobic sludge blanket reactor (UASB) and ahybrid UASB reactor. Profiles for the sludge, chemical oxygendemand and volatile fatty acids were determined. The results indicated that the optimum sludge loading rate was much lower for this type ofwastewa ter. Theinstallation of ropes in the mid-section of the hybrid reactor did not interfere with the flow pattern. The sludge blanket was a perfectly mixed region with respect to the liquid phase.Volatile fatty acids were degraded inthe sludge blanket region ofthe hybrid UASB reactor, while they remained high in theconventional UASB reactor. Inthis way, the stability ofthe hybrid reactor was greater, and it was more tolerant tohigher organic loading rates than was the conventional UASB reactor.
