Rising Sun Wastewater Treatment Plant
Rising Sun, Indiana
This project included expansion of the existing 0.36-MGD facility to 0.6-MGD average capacity and hydraulic capacity of 3.5 MGD. Preliminary design included preparation of material mass balances, hydraulic profiles, structure configuration and geometry, and equipment performance specifications to enable the development of a project budget. Final design and construction consisted of a submersible pump station, 2-mm bandscreen with a screenings washer/compactor and vortex grit chamber in the headworks, followed by sequencing batch reactors for biological treatment and ultraviolet disinfection before discharge to the Ohio River.
The biosolids stream is digested aerobically with coarse bubble tideflex diffusers in two new digesters equipped with decanters, then pumped through a grinder and centrifuge for dewatering. The centrifuge installation was retrofitted into the existing dewatering building, and the dewatered solids are conveyed by shaftless screw agars to dumpsters for disposal.
