Lehigh County Authority, Arcadia West Pump House Upgrade
Provide new Modicon
M340 PLC based control panel and add to existing SCADA system. Remote communications
were via cellular modem, to the authority’s operations center. Project was performed
in conjunction with a complete pump house upgrade, including; addition of variable
frequency drives; new pumps, instrumentation, generator, and chemical feeds.
Cosden Chemical Superfund Site:
Control system had numerous operational problems,
lacked proper documentation including wiring diagrams, and had a history of surge related
failures. Aptus performed field investigations and created wiring diagrams, troubleshoot
and repaired the operational issues, and addressed the surge related issues.
Aryzta Bakery (Hazleton, PA):
Reworked existing control panel to provide completely
automated control of this industrial wastewater plant. Project was performed in conjunction
with process optimization design, performed by Glace Associates. The completed project
significantly increased operational efficiencies, improving treatment, reducing operational
manpower requirements, and also reducing energy consumption and sludge hauling.
Lipari HMI replacement:
Project involved upgrading redundant Citect HMI PCs from
Windows XP to current Windows version. The original integrator was unable to complete the
project and after 9 months was removed. Aptus brought the HMI up to the most current
version and restored full operation.
