    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.
