Concerns of Aerobic Treatment
- Important Space needed - Energy Requirement for Aeration - Important Sludge Production - Sensitive to Loading Variation - Problems of Sludge Separation

Anaerobic process
COD CH4 + CO2 + BIOMASS
Anaerobic methanogenic biomass
Low growth rate
Production of reusable methane (green energy)
Low sludge production (& biomass is asset rather than waste)

Why anaerobic pre-treatment ?
- reduced energy consumption
- reduced sludge production
- more stable operation
- energy production
- reduced green house effect

High rate (20-30 kg COD/m3/d)
Small footprint
Low hydraulic retention time
Self regulating system
Intensely mixed biomass at bottom reactor
Optimal sludge retention at top reactor
BIOPAQIC reactor

26
Advantages BIOPAQ IC reactor
Proven technology, > 875 BIOPAQ references
Closed system, corrosion free materials
Minimal foot-print (space saving and odor emission
surface limited)
Completely mixed reactor compartment due to Internal
Circulation principle
Optimal sludge retention due to two-staged separation
Maximal recovery of biological alkalinity, reduced
chemical costs
Robust & more stable due to
- two-staged concept
- automatic internal dilution (IC)
