The Value Of Wave Integration With PRVs
10/19/2020
Distribution system water main breaks are a significant burden to communities and water systems not only due to disruption of water service to customers, but also due to significant economic burdens in the form of pipe replacement costs, excavation costs, and even insurance reimbursements. Read the full white paper to learn the KETOS Wave can be easily installed into existing PRVs to monitor the pressure and flow in the downstream side of the valve and proactively act in real-time as needed.

Optimal Coagulant Dosage Control Of Raw Water
2/3/2022
The following describes how combining of the latest data management and process management solutions can optimize the coagulation process. Coagulation is influenced by several raw water parameters. This new approach uses a feedforward model with machine learning of several raw water parameters for optimal coagulant dosage control. In addition, feed-back control can be used to trim the feed-forward model. In 2020, utilities that have installed the coagulation optimization system have achieved approximately 10% reduction in coagulant dosage while achieving similar settled turbidity.

Continuous Analyzer Integrated Data Validation
5/28/2015
Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
4/9/2018
Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

ORP Based Measurement Of Oxidizing Disinfectants In Aqueous Solutions
9/22/2011
Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications. By Myron L Company

Chloramination Monitoring And Control
7/15/2015
Since the EPA has established that, together with free chlorine, monochloramine is a primary disinfectant, it has been possible to implement the process more intensively. Water that is treated with monochloramine has, depending on the source of the water, fewer problems concerning taste and odor than water treated with free chlorine. In addition, the chemically more stable monochloramine remains longer in the water, thus allowing a long-term disinfecting effect.

The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It’s The Pressure, Not The Concentration)
8/5/2015
A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

Are You Experiencing Deviation Alarms In Your High Pressure Process Vessels?
4/9/2018
In this white paper, learn how to decrease alarms due to redundant level devices not matching, especially in applications with high pressure and/or high temperature. The importance of Gas Phase Compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can have an effect on the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.

Making Accurate pH Measurements
1/21/2014
Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.
