Demonstrating effective treatment

Swirl concentrators can remove floating material and heavy solids from the combined wastewater and storm water.

Swirl concentrators can remove floating material and heavy solids from the combined wastewater and storm water.

One of the most promising techniques for removing debris and other solid materials from the combined sewers in Syracuse is a swirl concentrator. In the 1970s, a small swirl concentrator was constructed near Onondaga Creek at Newell Street as part of a demonstration project.

Swirl concentrators are designed to treat combined wastewater and stormwater by removing floating material and heavy solids. The clarified water is disinfected before it is released.

The Newell Street facility was reactivated in 1998 to demonstrate alternative technologies for disinfecting the combined wastewater and stormwater in Syracuse.

The engineering evaluation found that it would be cost-effective to convey Newell Street CSO (067) to the Midland Avenue CSO transmission pipeline and subsequently the Midland Avenue RTF for treatment. See: Midland RTF and conveyances
