RIVERSTONE INDUSTRIAL PARK WWTP
NC0087084 Riverstone WWTP is located at 219 Broad River Blvd. inside the Riverstone Industrial Park. The plant is a 0.05 MGD permitted SBR plant consisting of:
Influent mechanical bar screen and manual bypass screen.
Pre-EQ basin with a maximum capacity of 0.017 MG.
SBR basin with a minimum capacity of 0.043 MG and a maximum capacity of 0.063 MG.
Decant flow rate (average high to low) 313 GPM. Sludge waste rate of 100 GPM.
Post SBR EQ basin maximum volume of 0.0156 MG. The flow control valve feeds the chlorine contact chamber at a rate of 0-0.033 MG.
The SBR has a default program for a permitted flow rate of 5 cycles/24 hour day:
Mixed-Fill 35 minutes (anoxic condition)
React-Fill 109 minutes (bowers running with floating mixer)
React Phase 35 minutes (influent pumps are locked out)
Settle 45 minutes
Decant 64 minutes
Idle 0-64 minutes (integral with decant)
Sludge Waste 2.26 minutes (integral with decant)
The cycles have programmability built in by PLC. These have been adjusted to accommodate the small flow rate currently received by the plant. Sludge waste is conducted manually as needed and is hauled to the plant headworks of the Forest City WWTP. The Riverstone WWTP was built in 2003 and began operation in November 2013. Influent flow ranges from 0.003 MGD to 0.0055 MGD of domestic and permitted industrial wastewater from industries within the industrial park and adjacent American Zinc Products facility.
