Biotrickling Filters

Biotrickling filters

• Biological treatment system
• Utilizes a plastic media with large specific surface for the stablishment of a biofilm and increasing gas-liquid transfer
• Smaller footprint than biofilters due to its design with shorter contact times and greater bed height
• Requires water supply with nutrients (normally filtered secondary effluent, or chlorine-free tertiary effluent)
• Continuous operation regime
• Sectors: urban and industrial wastewater treatment plants
