Looking Beyond Voice Modems in SCADA Systems
Looking Beyond Voice Modems in SCADA Systems

When I first came to Trihedral, I was surprised to learn that voice modems were still widely used in the HMI and SCADA industries. Though the days of wedging your phone receiver into a foam cradle are long gone, the name still conjures up the sounds of chirps, bleeps, and bongs they make as they translate analog information into digital. As high-speed networks became our preferred method of web surfing, the use of this technology has steeply declined.

WASTEWATER MANAGEMENT WHITE PAPERS AND CASE STUDIES

  • Ultrasonic vs. Radar In The Water Industry
    Ultrasonic vs. Radar In The Water Industry

    In recent years, the debate about which technology is best suited for level monitoring and open channel monitoring (OCM) applications has taken some traction. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and OCM applications in the water industry. The counter-argument is that radar technology is more effective because it is more robust and accurate than ultrasonic technology.

  • Enhancing Water System Reliability And Capacity For Boston Residents
    Enhancing Water System Reliability And Capacity For Boston Residents

    Enhancing process reliability and increasing capacity are common issues facing water municipalities. On the one hand, community demographics are constantly evolving and water municipalities need to accommodate the impact to capacity requirements. At the same time, older systems that support pumping operations are not getting any younger and as control systems age, for example, it can become more time consuming to maintain equipment and more difficult to find replacement parts after systems have been in place for many years.

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

Mazzei Degas Separators Selected For Wichita Aquifer Project Mazzei Degas Separators Selected For Wichita Aquifer Project

A key component of the water supply plan for the City of Wichita, Kansas, was recharging the large aquifer that lies under the region with water from the Little Arkansas River. The river basin contains substantial farming operations which, during rain events, spike the river water with the commonly used herbicide Atrazine. Atrazine concentrations in the river frequently rose forcing the city to shutdown the bank filtration system. Advanced oxidation process (AOP) was selected to remove the herbicide. The AOP reactor’s design limited the amount of hydraulic backpressure it could tolerate. Consequently, Mazzei was challenged by the project’s design team to remove the entrained gas bubbles that remained from the prior oxidation treatment at a “not to exceed” hydrostatic backpressure of 19 feet.
