Located outside of Knoxville, TN the brand new Melton Hill Wastewater Treatment Plant serves as the primary WWTP for West Knox Utility District. A new transfer pump station was constructed at the existing Karns WWTP to divert all flow to Melton Hill WWTP. Melton Hill WWTP consists of a new main pump station, headworks screening process, 4 SBR basins, UV disinfectant process, blower building, and sludge dewatering presses.
As the PCSS, Southern Flow provided the process instrumentation encompassing the flow, level, pressure, and analytical
measurements as well as 6 PLC based control panels featuring Allen-Bradley’s ControlLogix platform as the plants SCADA
backbone for each process building. Utilizing the Stratix managed ethernet switches, each process area was setup on an
individual VLAN for network segmentation and added security. Each building’s electrical rooms were home to Allen-Bradley
MCC’s with PowerFlex VFD’s and E300 Smart Relays which were controlled and monitored by the PCSS panels via Ethernet/IP
communications. Southern Flow provided the control and monitoring for the entire plant outside of the OEM packages. Southern Flow coordinated very closely with the OEM packages such as Xylem SBR, Trojan UV, and PW Tech’s dewatering presses to ensure that all control and monitoring signals were exchanged to ensure a smooth and functional operation.
Southern Flow provided a brand new 19” IT Rack with redundant Dell Blade Workstations running VTSCADA 11.5 Dual Server
Premium 5K tag licensing. Melton Hill’s VTSCADA application featured custom 3D rendered graphics and animations for the
entirety of the plants control and monitoring. Where applicable, the VTSCADA process screens for the OEM packages were setup with a scripted button to allow the operators to VNC into the OEM’s PanelView for additional control and monitoring from the main administration building. Also located on each of the 6 PCSS control panels were Dynic’s 18” panel PC’s running the same VTSCADA application as the main control room utilizing VTSCADA’s Internet Client to give the operators consistent interaction with their process.
