NEED FOR ANAEROBIC DIGESTION
• Removal of micro-pollutants not possible with existing treatment technology
• Need for complete treatment that meets DOE requirement• Strict water quality legislation for environmental protection• RENEWABLE ENERGY ACT 2011• RENEWABLE ENERGY ACT 2011• GREEN TECHNOLOGY POLICY
–– Tax incentives Tax incentives – Green Technology Financing Scheme
APPROACH
• “staging” promote separate environment of microbial populations
• Staging improves treatment of wastewater
• Can accommodate toxic slugs more efficiently by passing them in less time through the reactor system.
