MBBR system to be installed at Chicago WTP; first of its kind in IL state

Sponsored by


CARY, NC, Dec. 17, 2013 -- A new moving bed biofilm reactor (MBBR) system is set to be installed at the Metropolitan Water Reclamation District of Greater Chicago's (MWRD's) Egan Water Reclamation Plant (WRP) in Schaumburg, Ill.

The system, provided by Kruger Inc., a subsidiary of Veolia Water Solutions & Technologies, is the ANITA™ Mox MBBR -- the first to be adopted by the state. The MWRD awarded a contract to Kruger to install the technology in order to better treat a centrate stream between WRPs in the region as well as greatly reduce costs.

The Egan WTP currently dewaters the biosolids from both the Egan and Kirie WRPs, which produces a centrate stream with high ammonia concentrations. The centrate is then pumped to a gravity sewer, comingled with combined sewage, and then treated at the O'Brien WRP in Skokie, Ill., 20 miles away. The transport of the centrate stream creates problems such as potent odors and heavy corrosion in the MWRD's collection system and is a significant ammonia load to the O'Brien WRP. As such, the ANITA™ Mox system will allow this centrate stream to be treated at the Egan WRP.

Kruger's ANITA™ Mox is robust and stable and has a simple flow-through operation. As a MBBR process, it eliminates the need for additional solids management and is a more forgiving process when it comes to pH control. With a large percentage of the nitrogen removed, the ANITA™ Mox effluent can also be returned to the mainstream treatment process at Egan. This system provides the MWRD an ideal solution to efficiently treat their waste streams while simultaneously lowering their operating costs.

Further, the system is guaranteed to remove 75 percent of the ammonia and 65 percent of the total nitrogen in this side stream flow and will use 60 percent less oxygen than the current conventional treatment for nitrogen removal. Significant cost savings in these two areas, in addition to the savings generated by eliminating the need to pump the centrate stream off-site, will provide the MWRD great overall value that will significantly reduce secondary costs.
