High-rate anaerobic degradation of soluble organic pollutants is becoming very
popular, particularly for carbohydrate-based industrial wastewaters. Despite the
successes achieved, there are significant limitations in the application of this
technology to more complex wastewaters. These are defined as containing other
organic compounds such as particulate and soluble proteins and fats, and
originate from abattoirs (slaughterhouses), meat and food processing and similar
industries. Complex wastewater is often difficult to degrade and components
such as solids and fats have slow degradation kinetics and can diminish process
performance. Also, the growth of granular sludge, which is critical for optimal
performance in upflow reactors, is slow and granule properties such as shear
strength and settling velocity are poorer. This is reflected in a lower treatment
efficiency of 50%-60% in systems treating complex wastewater compared with
efficiencies of 85%-95% in carbohydrate fed treatment systems.
