PFAS Treatment Plant for Municipal Water System (Colorado):
Design/build project for new water treatment plant. The control system was based on Allen Bradley PLCs with a main plant MCP as well as several remote well RTUs. Remote telemetry involved a combination of ethernet, fiber optic, and cellular devices. A redundant HMI system was configured using Citect/Aveva Plant SCADA and we also provided a custom chemical fill panel for the safe filling of the treatment chemicals. A new MCC, VFDs, instrumentation, control valves, and associated components were selected, calibrated, and commissioned.
Hershey Creamery (Middletown, PA):
Design/build for a new treatment plant that was added to treat washdown water from new production lines. New electrical plans were developed for the plant lighting, power distribution, and the control system. Project involved Allen Bradley CompactLogix PLC interfaced with various vendor supplied equipment including a lift station, SAF units, and MBBR blowers with both hard wired and ethernet connections. A new MCC with ethernet connected Allen Bradley PowerFlex VFDs, instrumentation, and control valves were specified and commissioned. Human Machine Interfacing was achieved via PC running FactoryTalk View SE.
Harrisburg International Airport Water Treatment Plant (Middletown, PA):
Upgrade and retrofit of an existing 680-acre campuswide water distribution SCADA system that involved communications and integration between 7 buildings (2 new) and two elevated tanks (one remote). The existing SCADA system HMI was also upgraded with a redundant server, using Ignition HMI software. Project involved control and process enhancements, removal of obsolete equipment, and was performed without any service interruptions. Communication between miscellaneous locations was achieved with a combination of radio, fiber optic, and plantwide ethernet devices.
Lykens Water Plant (Lykens, PA):
Upgrade project replaced 5 obsolete Automation Direct PLCs with new Schneider Modicon M340s for this surface water sand filter-based plant with a remote raw water intake building. We provided a new main control panel with panel-mount HMI as well as a redundant office-based HMI PC. New Modicon PLCs were retrofitted into existing control cabinets, and the original electrical drawings were scanned and electronically updated. OITs were added to each filter panel to provide local visual feedback and control of the filter process. Communications from the plant to the intake building were achieved using Moxa line drivers to permit use of existing twisted shield pair for ethernet communications.
Remediation Plant Control System (Pennsylvania):
Upgrade project for Fortune 500 manufacturer, involved design, fabrication, programming, installation oversight, and commissioning of new control system for existing groundwater remediation system. Three existing PLCs were consolidated into a single control panel. We provided an enhanced safety-oriented motor and plant control system which included a new remotely accessible plant floor HMI in a footprint roughly 1/3 of the original control system.
GEMs Landfill (Gloucester Township, NJ):
Upgraded obsolete PLCs to Schneider Modicon 340s for two indoor control panels in the treatment plant and two remote outdoor panels. The control of the two outdoor panels was migrated into one M340. Abandoned wiring was removed while some existing wiring was repurposed for an added new remote pump station. Moxa line drives were used to allow for the reuse of the existing twisted shielded pair for ethernet communications between the main plant and remote panels. The outdated HMI was replaced at the treatment plant with an HMI running Aveva Plant SCADA and a redundant HMI added to the site’s office trailer.
