Anaerobic Process

COD CH4 + CO2 + BIOMASS

• No oxygen addition• Low growth rate• Production of reusable methane (green energy)• Granular biomass can be stored/sold• Small footprint – especially high rate systems• Less nutrient required

Theoretically,

Every Kg of COD removed 0.43 m3 Biogas

Equivalent Methane content 0.35 m3 CH4

In terms of Calorific value 11.6 MJ of useable energy

In terms of Electric power 1.8 kwh /kg of Biogas

Biotechnology makes the difference

Anaerobic wastewater & gas treatment

• savings on operational costs with production of green energy

• Reduce freshwater intake

• reduction in emissions

• recover valuable elements

• reduction on discharge costs

• smaller footprint

• minimize neutralization costs
