Secondary treatment with membrane bioreactor (MBR), with nitrogen removal (nitrification-denitrification)

REF: CHC-OXI-MBR

• High efficiency removal of organic matter, suspended solids and ammonia.
• System suitable for reuse of treated wastewater.
• Technology: membrane bioreactor (MBR). Biological treatment with separation of biomass from clarified water by ultrafiltration membranes at atmospheric pressure.
• Compact, modular, very efficient, easy installation and operation
• Manufactured in GFRP (Glass Fiber Reinforced Polyester), certified
• Ultrafiltration membrane with pore diameter < 0.1 µm
• Effluent suitable for reuse in accordance with Australian Recycling Guidelines
• High quality effluent with separation solid/liquid
• High efficiency: BOD5: 99%; COD: 95%; N-NH4+ : 82%; TSS: 99%; faecal coliforms: 99.9%.

Advantages:

• High quality of the effluent
• Effluent 100% free of virus, bacteria and other pathogens
• Reduction of the surface required compared with traditional technologies: 65-75%. Removal of secondary settling tank and reduction of biological reactor volume
• Secondary settling tank replaced by ultrafiltration membranes. Technology with excellent separation clarified water/sludge. No problem linked to sludge settling
• Flexibility increased to face peak flows and contaminating loads
• No smell
• No bulking problem
• Sludge quantity is lower and more stable. High sludge age and less mass loads
• High level of automation
