Using SCADA To Find Hidden Problems And Solutions
By Trihedral Engineering Limited |
| Ocean Isle Beach is a small island community on the southeast coast of North Carolina. Only about 500 people live there year round, but during the summer months its beautiful beaches draw almost 10 times that number. This poses unique challenges for the town's wastewater utility which must handle this extreme seasonal spike in usage.
In this article, David Kanoy, president of Kanoy & Kanoy Inc., a systems integrator based in Supply, NC, describes the supervisory control and data acquisition (SCADA) system he developed for the town and how it is already saving money by collecting accurate usage patterns, identifying unseen mechanical problems, and freeing staff to do proactive maintenance.

ABB Flowmeters Help Cut Water Leaks By A Half Billion Gallons/Year In UK
By ABB |
| Electromagnetic flowmeters from ABB are playing a key role in cutting water leakage for the Ministry of Defense (MoD) in England, with reductions of 60% achieved at some sites. Leakage has already dropped by about 528 million (US) gallons per year across more than 1,500 MoD sites where C2C Services manages water and waste utility assets.
C2C's water resources manager says that the AquaMaster magmeters from ABB have been central to the success of C2C's leak reduction program. |

New Sensor Technology Optimizes DO Control
By Bob Dabkowski, Hach Company |
The key to optimizing the aeration process is accurate and reliable dissolved oxygen (DO) monitoring and control. To achieve this, the Duck Creek Wastewater Treatment Plant has adopted advanced luminescent technology for online DO monitoring.
Although activated sludge systems are less expensive to build than trickling filter plants, they are typically more expensive to operate because of the need for greater energy to run blowers for aeration. The key to optimizing the aeration process is accurate and reliable DO control. |

Online TOC Measurement For Effluent Monitoring And Environmental Protection
By Endress+Hauser, Inc. |
| Measuring organic content is of
fundamental importance for the management of wastewater treatment plants, for monitoring surface water, and for aqueduct distribution. TOC (Total Organic Carbon) has been one of the most widely used parameters for some time for monitoring the organic content of water, whether surface water or wastewater. Its success is due to the practicality and relative simplicity of measurement in the most varied of
applications. |

SCADA As A Preventive Maintenance Tool
By ITT Water & Wastewater — Flygt Products |
| Granite City, IL, recently joined the increasing number of municipalities that have invested in supervisory control and data acquisition (SCADA) technology to more effectively manage their community wastewater systems. Improvements in both the hardware and software have advanced the technology's capabilities far beyond the limits of first-generation control systems that reached market in the 1960s and 1970s. |

The FS2000 insertion type NuTec represents the first thermal flow switch designed with two-wire, 4 to 20 mA loop power. Using 24 Vdc input power, this design allows for retrofitting existing two-wire, failure-prone, mechanical float and paddle switches without wiring modifications.
The Model 54e family of analyzers, with the appropriate sensors, monitor, and control pH/ORP, conductivity/resistivity, dissolved oxygen (ppm and ppb level), free chlorine,
total chlorine, or ozone in a variety of process liquids.
The E-Series Meter is an electronic, solid-state meter with no moving parts, so it's not prone to premature wear that can shorten its lifespan. The E-Series Meter is also incredibly accurate — within 1 percent over the range of flow rates — regardless of water quality, air bubbles, sand particles, or pressure fluctuations.
Retractable sampling probes can be inserted into a pressurized main up to 150 psi. A mechanical assist may be needed for pressures above 100 psi.
Aqua-Aerobic Systems, Inc. offers design and development of electrical control panels and supervisory control and data acquisition (SCADA) systems, targeted for wastewater treatment equipment and processes.
Mazzei Injectors are high-efficiency, venturi-type differential pressure injectors with internal mixing vanes. When a sufficient pressure difference exists between the inlet and outlet ports of the injector, a vacuum is created inside the injector body, which initiates suction of a liquid or gas through the suction port.
The Real UV254 Hi-Pure Online Monitor provides real-time detection of trace amounts of organics in high purity waters. The monitor utilizes innovative technology to provide extreme accuracy at a fraction of the cost of alternative organics monitors (such as TOC).
The OPTISOUND VU30 ultrasonic transmitter provides a reliable, repeatable, and highly accurate (0.15%) continuous level measurement of liquids. It is capable of liquid level measurement to ranges up to 30 ft. (9.1 m), with a two-wire, 4-20mA, HART output signal.
The Royce Interface Level Analyzer makes it possible to
reliably monitor and control the solid/liquid interfaces in settling tanks and
clarifiers regardless of the size of the plant, process, or budgetary
constraints.
Built on the proven SCADAPack 300 Series platform, the SCADAPack 314 is a purpose-built controller ideal for remote installation requiring advanced processing, low power consumption, and serial
communication.
When any combination of local indication, a 4 mA to 20 mA signal, and switching are required to meet your needs, the Ashcroft digital industrial gauge provides the solution.
The OI Analytical CNSolution FS 3100 is a flexible, safe, high-throughput, multifunctional, automated cyanide analyzer. It incorporates a single- or dual-channel analyzer, WinFLOW software, and a 90-position random access
autosampler.
Whatever your supervision requirements, Vijeo Citect SCADA software has the answer. From a standalone control station to a redundant supervisor, a SCADA solution exists that is perfectly suited to your specific needs.
The FC100 and FC101 are ideal for both local direct reading and remote or large SCADA monitoring applications in a wide range of water and water treatment applications. With its remote-mount option, the FC100 and FC101 can be mounted away from confined spaces where combustible and hazardous gases may be present.
The Ultrameter II is a prime example of how high-tech engineering can greatly simplify and streamline a task. While priced like affordable, single-parameter instruments, the Ultrameter II does the job of three, four, or even six
instruments.
The Jerome 651 monitoring system from Arizona Instrument is the tool you need to solve your hydrogen sulfide emission problems. Designed to provide long-term monitoring even in extreme weather conditions, it can be stationed at any location that requires monitoring.
