Midwest City Water Resources Recovery Facility Completes Upgrade

Midwest City Water Resources Recovery Facility recently completed construction of their new facility, an upgrade of an old RBC system to an MBBR system, and will host a grand opening on Monday, May 16, from 10 a.m. to 12 p.m. Back in January 2012, the Oklahoma city engaged Black & Veatch, an engineering, consulting and construction company, to lead project design. After looking into many treatment technologies, Black & Veatch ultimately selected a moving bed biofilm reactor (MBBR) technology from World Water Works.

“Midwest City was faced with a municipal wastewater system that had not been upgraded in more than 25 years and with new nitrogen effluent permit limits along with having insufficient influent screening, existing rotating biological contactors (RBC’s) which were a mechanical nightmare for the operations and service staff and a lack of a modernized computer system,” said Chandler Johnson, chief technology officer at World Water Works. “It was certainly time for an upgrade and we were glad to be a part of the overall solution aiding in upgrading the facility to the latest in nitrogen removal technology.”

With the MBBR system as the heart of the upgraded facility, World Water Works and Black & Veatch collaborated on all aspects of the installation. This included new systems feeding into the MBBR; a new headworks building for screening of influent, a grit building upgrade for more efficient grit removal, and new clarifier equipment and primary sludge pumps.

Now fully operational, the new MBBR-based wastewater treatment facility in Midwest City is functioning at full capacity. The MBBR provides a number of long-term benefits including more efficient and effective treatment of wastewater, improved clarity and quality of water discharged into the environment, reduction of the overall footprint of the facility and more allowed expansion to meet future needs.

In addition, the system’s operational simplicity and modern computer control system reduce the potential for breakdowns, facilitate faster repairs in the event of a problem, provide better monitoring of all processes and maintain more effective wastewater treatment facility for many years to come.
