Water and Wastewater Treatment Solutions
MABR Technology Validated by Industry Experts
Black & Veatch independently validated the upgrade goals of the Mayan Zvi SUBRE installation were met and increased
capacity achieved
What have we learned about the MABR?
Fundamental
Understanding
• Microbial
Community
Structure
AOB/NOB ratio
Operational
Challenges
• Optimal SRT
Impact of C:N ratio
• Resilience
• Robustness
• Quorum sensing
• Biofilm
Management
Scale up
Challenges
•No of membranes
• Nitrification rate
Key remaining research questions are site specific and related to whole system
integration
