Although, we Belgians, speak at least 3 languages, we know that:

In Belgium, the DILUTION is NO SOLUTION for the POLLUTION

Belgium has created a very performant environmental business

Drinking Water and Water Reuse

Municipal Wastewater Treatment

• Large surface area required

• Open tanks, no odour control

• No biological nutrient (N&P) removal

• Low effluent quality (no tertiary treatment)

• No effluent reuse

• Low-energy efficient aerators

• No energy recuperation from the sludge

• No valorisation of the sludge

• High costs for sludge disposal

Conventional plants in the 80’s

Energy consumption: 2kWh/m³

Total costs: 0.5 €/m³

Municipal Wastewater Treatment

• Compact

• Covered with odour control

• Biological nutrient (N&P) removal

• Superior effluent quality (tertiary treatment)

• Reuse for irrigation

• Highly efficient fine bubble aeration

• Wind and Solar Energy

• Energy recuperation from sludge

• Sludge valorisation (drying & incineration)

• Low costs for sludge disposal

Modern plants

Energy consumption: 0 kWh/m³

Total costs: 0.25 €/m³
