SCADA upgrade for sludge tanks, DO tanks, chlorine control, hypo tanks, thickeners and digesters including all field devices, enclosures and communication systems.

Our customer had a SCADA system in place that monitored the boilers and the gas detection system. However, an excessive amount of time was spent collecting data from remote chart recorders and indicators.

The Iconics SCADA system was expanded four-fold in order to bring in many remote parts of the plant. Twenty-five new stainless steel enclosures were installed— each being connected back to the control

room with a mix of serial comms, ethernet radios,fiber cable and copper ethernet. This meant that five-hundred new I/O was added to the control room screens along with alarms for dozens of key plant parameters.

With the new SCADA system in place, the time spent driving to remote parts of the plant has been significantly reduced as was the speed with which problems could be identified.

Application Note: Monitoring Methane at a Landfill

March 15, 2024 | Application NotesMunicipal: Water / Wastewater / Landfill

Flare System Retrofit A Turnkey Solution

Problem

Outdated Control System for Flare Operation

A landfill customer was in need of a new control system for their flare operation— a secondary disposal path for methane. Their current system was 20 years old, outdated, and remained dormant for 4 years.

Their old panel had an obsolete circular chart recorder. Since their system was down for 4 years, NSI worked with them through the process of identifying potential roadblocks and old units that needed to be replaced.

Solution

Neal Systems redesigned and retrofitted their old system with custom screens and newer technology, creating a cleaner, EPA compliant, operator interface.

NSI retrofitted and rewired their current panel with Foxboro Scadapack 474 RTU and Eurotherm Nanodac for recording and PID loop control. The Scadapack 474 is ruggedized and able to operate in harsh environments, which makes it the perfect solution for outdoor operations.

Conclusion

 
With Neal Systems’ solution, the landfill’s methane flare is operable and compliant with EPA regulations and recording requirements. The new solution provides the customer with reduced operator involvement in startup and operation. They can simply turn it on and forget about it. Our customer now has a viable secondary disposal path for methane in the event that their generators are unavailable.

Wireless Communications Network Improves Sewage Plant Efficiency and Preparedness

Neal Systems supplied both hardware and engineering services to assist a major northern New Jersey wastewater treatment plant in designing, implementing, and integrating into the plant SCADA a wide area wireless communications network.


Consisting of more than 90 unlicensed 900 MHz and cellular I/O radios, the network linked together remote instrumentation stations within a municipal sewer system covering a region approximately 200 square miles in size. In addition to an I/O radio, each remote station contained instruments and sensors for measuring sewage flow, level, and toxicity levels at each of over 80 locations throughout the entire sewer system.

 

The wireless network delivered remote station data to the plant SCADA where operators could analyze it and take appropriate action to ensure the plant was adequately prepared to process the amounts of raw sewage the remote stations predicted was headed toward the plant.


The network greatly improved plant efficiency and its ability to quickly react to changing influent conditions – most especially in times of when run off from fast moving rainstorms or melting snow caused by unexpectedly warm winter weather would otherwise strain plant resources.

Application Note: Revolutionizing Laboratory Gas Monitoring: A Cost-Effective Solution

February 5, 2024 | Application NotesLife Sciences

Problem

A pharmaceutical customer in Pennsylvania required a solution to help monitor toxic, flammable, and O2 depleting gases in their laboratory. They need the ability to change the sensors depending on what gases are being detected at the time; in this case – oxygen (O2) and Silicon Tetrachloride (SiCl4). The detectors they have are permanent, meaning that once they install the unit, they have to replace the entire thing to sense a new gas— a very inconvenient and costly task. 

 

Not only that, but their existing system was a rat’s nest of wires with little to no drawings. It was retrofitted so many times to the point where nobody understands how the system functions anymore. In fact, the customer was having a difficult time finding anyone with the knowledge and expertise to help them. That is when the Neal Systems team came to help.

Before
Before

Solution

After troubleshooting and testing the pre-existing equipment to know how everything worked together, Neal Systems demolished obsolete portions of the existing cabinet and repurposed what we could. Their existing equipment was retrofitted with a new Draeger Regard 7000 enclosure, several Draeger Polytron 7000 transmitters, gas detectors, and new light stacks. Our solution simplifies the process to exchange sensors, and the controller can recognize exchanged sensors and recommend settings based on what is plugged in.

The Big Reveal

Our solution allows the customer to change out multiple gas sensors with relative ease. The system can recognize the different sensors that are plugged into the transmitters, and even recommend when the sensor life is near an end so that they can be proactively changed out. The customer no longer has the hassle of replacing detectors when they need to monitor new gases. We’ve also updated the drawings so that future work and expansion of the system would be feasible. The solution we provided to our customer was cost-effective, quick, and efficient, thanks to Neal Systems’ Engineering team and Draeger’s advanced technology, especially the Regard 7000 Gas Detection System.

enclosure

SCADA upgrade for gas detection, alarm annunciator replacement, wet well, MSP’s, DO tanks, digesters, hypo tanks, chlorine control and final effluent including all field devices, enclosures and communication systems.

Our customer’s previous system covered only half the plant and did not provide any reporting or reliable alarming. The operators never used the system because of communication failures and unreliable data.

The system NSI designed was entirely Ethernet based, but used copper, fiber, and wireless to reach all areas. Cyber security was designed into the system with whitelisting and MAC address filtering along with a firewall performing deep packet inspection. Different remote I/O racks, multi-loop controllers, PAC’s and OIT’s were used to bring in the 400 new I/O points— all using either Modbus RTU or Modbus TCP.

NSI brought a specific expertise in Chlorine dosing control to the facility, reducing their Sodium Hypochlorite consumption by 15% whilst improving the stability of the residual Chlorine.

The plant finished up with a system that included all areas allowing operators to monitor a sizeable area from a central location. Remote view nodes using a browser allowed management to interrogate the plant at any time and the added reports allowed for more effective regulatory compliance.
