MWRD Selects UV System for Water Reclamation Plant

The Metropolitan Water Reclamation District of Greater Chicago (MWRD) has selected TrojanUV’s newest wastewater ultraviolet (UV) light disinfection system, the TrojanUVSigna. The system is specifically designed for large-scale wastewater disinfection applications, making adoption of UV disinfection easier, reducing the total cost of ownership compared to chemical disinfection and simplifying maintenance for the wastewater treatment plant operations staff.

“We’re proud to be working with the design engineering firm Greeley & Hansen on the design of the UV disinfection system, and MWRD staff who will manage the construction contract on this installation,” said Marv DeVries, president of Trojan Technologies. Trojan will be supplying fourteen UV banks equipped with revolutionary TrojanUV Solo Lamp technology.

The UV system in Chicago will have a flow capacity of 450 million gal per day making it one of the 10 largest wastewater treatment plants in the U.S. Out of the top 30 largest wastewater treatment plants in the U.S., Chicago is the first to use UV technology. The system is expected to be operational in 2015.

The Terrence J. O’Brien Water Reclamation Plant is an activated sludge, single stage nitrification plant. The plant, located in Skokie, Ill., began operation in 1928 and currently serves over 1.3 million people in a 141 sq mile service area. The plant currently discharges secondary effluent from the secondary clarifiers into the North Shore Channel of the Chicago River, which is part of the Chicago Area Water System (CAWS) that is designated for primary contact recreational use. Recent regulations have required the facility to add a disinfection process to further enhance the water quality of the discharging effluent.
