“…For anaerobic granulation, it was found that the development of granular sludge depends on the seed sludge characteristics, feed composition, hydraulic loading rate, temperature, etc. Changes in the composition of wastewater, organic loading rate, and pH can affect the internal structure of the granules (Pavlostathis et al 1997). Jhung and Choi (1995) suggested that the sludge granulation is more influenced by the type of wastewater rather than the type of reactor used.…”
