AUMA Electric Actuators for Critical Flow Control, Safety, and Security in the Water Industry
Automatic Samplers Assist in Detection of Pathogens, Viruses & CECs via Wastewater-based Epidemiology
WBE (or wastewater-based epidemiology or sewage chemical information mining) is a technique for identifying a population's consumption or exposure to chemicals or diseases. A sewage treatment facility measures chemical or biological entities (biomarkers) in municipal wastewater to do so. In addition to illicit drug usage, wastewater-based epidemiology can quantify alcohol, caffeine, medicines, and other chemicals. Wastewater-based epidemiology can also detect diseases like SARS-CoV-2 in a population. Wastewater-based epidemiology is a multidisciplinary effort including wastewater treatment plant operators, chemists, and epidemiologists.
Professionals in water quality use the term contaminants of emerging concern (CECs) to describe pollutants found in water bodies that may harm the environment or human health but are not currently regulated. Agriculture, urban runoff, ordinary household products (like soaps and disinfectants) and pharmaceuticals are all sources of these pollutants.
Natural and synthetic hormones are emerging contaminants, as is 1,4-dioxane. CECs can enter the water cycle after being discharged as waste via runoff into rivers, effluent discharge, or seepage and infiltration into the water table, eventually entering the public water supply system. Some emerging contaminants are known carcinogens and cause endocrine disruption and other toxic mechanisms.
The full line of Teledyne ISCO samplers can assist local governments, private industry, colleges and universities, and many others in detecting the COVID-19 virus, pharmaceuticals and CECs in wastewater and providing the information needed to create a plan of action.

The Ideal Air Release Valve for Chemical, Desalinization, Sewage, and Other Severe Applications
The Crispin X Series elevates valve maintenance into the twenty-first century. All of the valve parts are made of stainless steel, making them rustproof. Instead of a bolted, flanged connection, the X series uses a stainless circular clamp to secure the valve head to the body for the tightest seal in the industry.
The X Series, available in Air & Vacuum, Pressure Air Release, and Combination assemblies, features Crispin's exclusive Head Exchange System, which includes head-fixed stainless steel valve internals. Simply loosen the head assembly, held in place by a sanitary stainless clamp fitting, to clean. Remove the original head, which weighs less than 10 pounds, and replace it with a spare. Then, at your leisure, clean the original internals. Backflushing inline is no longer possible. No more annoyances. ANSI/AWWA C512 compliant.
The internals of all valves are attached to the head, which is available in three color-coded configurations: red for the Air & Vacuum valve, green for the Pressure Air Release valve, and blue for the Universal Combination valve. Each product's packaging is also color-coded for easy storage.
When backflushing an inline X Series valve, the spare head replaces the original valve head immediately, allowing proper cleaning to take place off-site in a safer and more sanitary environment.
All that stands between you and a clean valve with the X Series is a wrench, two bolts, and a clamp.
All of the valve heads fit the same virtually indestructible 316 stainless steel body. It is one-third the weight of a standard cast iron body and has a polished interior that prevents buildup because debris has nothing to cling to. Crispin valves are all tested under the most recent ANSI/AWWA C512 standards.

Smart Wastewater Pump Stations with MAID Labs Volucalc™
A wastewater lift station is a pumping station that transports wastewater from one elevation to another. They are essential in transporting sewage to a wastewater treatment plant. Lift Stations are an integral part of the overall infrastructure of the wastewater industry. They improve the efficiency with which sewage transports to treatment facilities. They also reduce the cost of installing underground sewer pipes. It is critical for wastewater treatment operators to closely monitor the health and efficiency of their equipment, paying close attention to alarms and notifications. Monitoring not only extends the life of the equipment but also ensures public safety (sewage is a hazardous material that must be handled and transported with caution.)
Multiple operational parts and components make up a functional wastewater lift pump station. Everything from a power supply to remote monitoring and control must be functioning to collect and treat wastewater properly.
A Flow-Based Lift Station Operating System changes the operation of the pumps based on the flow rate entering the lift station in real-time, increasing the pumps' capacity by reducing the head. It raises its ability to cope with storm surges by lowering the lead level during high flow conditions. Real-Time flow rate monitoring is mandatory to respond to rapidly changing conditions.
Consistent monitoring is required to operate and maintain a wastewater lift station properly. A cloud-based monitoring system is the most effective approach to monitoring and controlling a lift station because they are simple, inexpensive, accurate, and accessible from anywhere. Such monitoring systems give wastewater operators access to data about their lift stations, including alert notifications and historical data graphs and charts. Monitoring ensures that lift station equipment is in good working order and protects the public by giving vital information about the wastewater being transported and processed.
MAID (Municipal And Industrial Data) Labs created the only wastewater pump station computer that significantly reduces the electrical consumption using the existing equipment. Power consumption, pump efficiency, level behavior, and real-time high precision volumetric flow metering are some elements used to highlight the embryonic catastrophic situation. The MaidLabs' Volucalc™ Hybrid Series provides a better way to manage wastewater pump stations and is the future of lift station analysis.
Volucalc™ Hybrid CS (Constant Speed)
VOLUCALC™ HYBRID CS is a volumetric flow meter and an open channel flow meter applicable to lift stations with constant speed pumps reporting abnormal behaviors using real-time diagnostics with flow and efficiency monitoring. The CS potentially decreases electric bills by 15% to 30% using the flow-based operating system.
Volucalc™ Hybrid VS (Variable Speed)
VOLUCALC™ Hybrid VS is a volumetric flow meter, a derived flow-based flow meter, an open channel flow meter, a backup pump controller, and an efficiency optimizer applied on lift stations having constant speed and variable speed pumps. On constant speed pumps, flow is calculated with a volumetric algorithm. On variable speed pumps, the flow rate is derived from the calibrated pump curves. A rain gauge can also be connected for infiltration studies.

Video Demonstrates Teledyne ISCO Automatic Sampler's Real-World Role in Detecting COVID-19 in Wastewater Systems
Researchers at UC Berkeley are using a simple and effective method for detecting the presence of the Coronavirus in wastewater flowing through municipal sewer systems. Water testing will assist public policymakers to determine where and how to implement COVID-19 prevention and treatment plans.
Wastewater testing, also known as "wastewater quality indicators," is a broad term for the various test methodologies used to measure water quality. These tests investigate the physical, chemical, and biological properties of wastewater. Wastewater naturally collects waste from hundreds to even millions of people in a single sample. By drawing a representative sample of wastewater and analyzing it, you can gain a tremendous amount of information that you would likely not be able to achieve by testing people individually.
The amount of viral matter in wastewater from a community could reveal the prevalence of COVID-19 in the population. This information can trigger the necessary mitigation initiatives and response plans, such as individual testing, contract tracking, and quarantine. It also allows for collecting data on a cross-section of the population, allowing for the monitoring of public health solutions for large groups. However, it is challenging to detect tiny virus particles in the wastewater that flows through our sewage pipes, considering it includes toilet water and sink water, shower water, and everything else that goes down the drain. Teledyne ISCO is leading the way in the use of automatic samplers for gathering wastewater to identify virus evidence in sewage.
Teledyne ISCO is a leading manufacturer and supplier of rugged, dependable field-portable instruments for water quality monitoring. Their automatic sampler readings analyze the characteristics and presence of the Coronavirus in parts per million quantities, which, when compared to population numbers in a geographic area, aids in determining the presence and amount of virus in the wastewater.
The above-referenced UC Berkeley videos provide a real-life example of how the Teledyne ISCO water sampler collects wastewater for COVID-19 analysis. In this video, samples are gathered from their University Village and sewers draining from UC Berkeley's undergraduate dormitories and surrounding neighborhoods.

Control Valve Cavitation Solutions
Cavitation is the formation of vapor spaces (bubbles) in the control valve cavity resulting from a rapid change in pressure. When the bubbles move downstream and are exposed to a larger cross-sectional area, velocity decreases and pressure increases, the surrounding higher pressure causes the lower pressure bubble to implode, which causes shockwaves. These shockwaves can cause metal fatigue and cause excessive wear on the internals of the valve. As the bubbles collapse, they make a discernible sound with accompanying vibration, and the damage to a valve can happen quickly (weeks or months).
Cavitation is very destructive and may wear out the trim and body parts of the valve in a short time. Using hard internal materials provides a slight improvement but costs more.
Flowserve Valtek Cavitation Solution Control Valves prevent cavitation damage and minimize hydrodynamic noise even under the most severe liquid applications. Their unique, patented designs eliminate cavitation damage and provide straightforward maintenance and a long life even with demanding applications.

Pressure Switches Are Unsung Heroes in Many Process Control Applications
In today's highly connected world of process control instrumentation, the unacknowledged and uncelebrated pressure switch quietly does it's job protecting people and equipment from unsafe conditions and ensuring consistent, efficient operation.
A pressure switch is an electromechanical device that senses fluid pressure and responds by opening or closing an electrical or pneumatic circuit. That's it. That's their job.
However, pressure switch applications exist in almost every water treatment plant, power plant, refinery, chemical plant, paper mill, steel mill, or other manufacturing plant. Pressure switches are everywhere.
Pressure switches are easy to use and consist of four essential components: a pressure port or connection; a sensor that moves in response to changing pressures; an electrical or pneumatic switch that opens or closes in response to movement; and finally, a housing that protects the pressure switch's internals from the environment.
SOR pressure switches, the recipient of a 2021 CONTROL Readers Choice Award, have been field-proven in many industries for primary and redundant pressure applications. SOR continues to broaden its product ranges to meet evolving market needs, even though the technology of the initial Static "O" Ring mechanical switches set industry standards more than 50 years ago. In any situation, there's a SOR switch designed to meet or exceed the minimum requirements for any hazardous area or agency approval.
SOR pressure switches are designed and offered with various agency permits, housing enclosures, sensor materials, and switching configurations. The wide range of product components allows for the best instrument configurations to handle even the most demanding applications.
