CASE STUDY: Headworks
When the City of Rogers designed and specified a new headworks facility at its award-winning wastewater treatment plant, they followed their internal philosophy to “do the very best job we can.” Grit removal had previously caused problems following large flow surges that often overwhelmed the original grit and scum system.
True to their philosophy, plant staff undertook a thorough evaluation process. Their course of action included numerous visits to other wastewater treatment plants, collaboration with colleagues and meetings with various equipment suppliers. They observed and evaluated several grit removal approaches, ultimately choosing to go with a vortex-type approach. Even still, the new flow conditions posed challenges for a vortex chamber design. Low daily flows compared to the peak flow would typically necessitate multiple vortex grit chambers and the use of downstream leveling devices to effect proper channel velocities required to move grit.
