Not “Rolling the Dice”: A structured approach to starting up two large MBR facilities in the Las Vegas basin

Two large BNR MBR facilities were commissioned in the City of Henderson (Henderson SWRF) and the City of North Las Vegas (CNLV WRF) in the summer of 2011. In both cases, dynamic process modeling using BioWinTM was completed to support decision making during facility start-up. This paper demonstrates how good planning, through the use of process modeling and a strong understanding of the challenges and opportunities provide by MBR technology, assisted in the start-up of two large BNR MBR facilities.
