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
coagulation flocculation decantation sandfiltration storage, disinfection & distribution
Conventional treatment Membranes
Still used today Since mid ‘90’s: sand filtration
is replaced by membranes
Conventional drinking water treatment Water reuse by sandfiltration and disinfection
Water reuse by membrane filtration Water reuse by membrane filtration
Saudi Arabia - 20.000 m³/d Morocco - 120.000 m³/d

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
Belgium - 200.000 PE – 73.000 m³/d Macau - 550.000 PE – 130.000 m³/d

• Organic load: 4 kg COD/HL beer
• Conventional Activated Sludge
• Hydraulic capacity: 10.000 m³/day
• Organic capacity: 30 ton COD/day
• CAPEX: 12 Mio €
• OPEX: 3 kWh/HL beer
• TOTAL: 2,0 € /HL beer

Industrial Wastewater Treatment
• Capacity: 3 Mio HL/year
• Water to beer: 3 HL/HL beer: 4 x less
• Organic load: <1 kg COD/HL: 4 x less
• Anarobic-aerobic treatment + water reuse
• Hydraulic capacity: < 3.000 m³/day
• Organic capacity: 9 ton COD/day
• CAPEX: 4 Mio € : 3 x less
• OPEX: 0.3 kWe/HL beer: 10 x less
• Total cost: 0,25 €/HL beer: 8 x less
• Sludge (@20%DS): 0.25 kg/Hl beer
