Applications for Thermal Flow Meters in Wastewater Treatment Plants

Thermal Flow Meters in Wastewater Treatment

Wastewater treatment plants ( WWTPs) or publicly owned treatment plants (POTWs) must operate 24/7 to satisfy domestic, industrial, and storm drain sources. Sewage treatment includes eliminating pollutants from wastewater and sewage (human waste, animal waste, soaps, and detergents) to create a safe fluid waste stream that can be reintroduced safely into the ecosystem and a solid waste appropriate for reuse (usually as fertilizer). The primary applications for flow meters in wastewater treatment settings measure blower air to each pool in the aeration basin and measure digester gas flow.

The aeration basin is an array of treatment pools containing aerobic bacteria that breaks down sewage. A blower adds the necessary dissolved oxygen (DO) to the aerobic bacteria in the aeration basin. Too little oxygen destroys the bacteria, and too much oxygen is expensive; running the aeration blower accounts for up to 60% of all wastewater power consumed.

Digester sewage is called "sludge." When bacteria is added to the digester, the sludge breaks down and releases gas. This digester gas is collected, compressed, it's excess moisture gets removed, and is then cleaned in a scrubber. The clean gas is sent to engines or fuel cells for power generation, boiler water heating (for steam or hot water), and excess gas burns off at the flare. Many extensive sewage treatment facilities use digester biogas to operate the plant, minimizing their grid power consumption.

Developing accurate flow rate data allows wastewater treatment facilities to more precisely manage digester production levels, enabling tighter controls on methane levels and flaring. Kurz Instruments provides a handy application brief explaining where thermal flowmeters are applied.

Disc & Seat Replacement for the Jordan Mark 701/702 Series Sliding Gate Control Valve

This six-minute video teaches the viewer how to replace the sliding gate and associated parts for the Jordan Valve 701/702 Series control valve.

The Mark 701/702 high-flow and super high-flow sliding gate control valves provide shorter stroke than a globe or plug-style valve, straight-through flow, and ease of maintenance.

A side or top-mounted positioner is available to overcome the typical hysteresis for a control valve and actuator and to ensure that the valve stem position is always directly proportional to the control valve command signal.

Non-intrusive, Non-invasive Fluid Identification and Condition Monitoring with Perceptive Sensor Technologies

Perceptive Sensor Technologies

Did you know there's an innovation that can now identify any fluid inside any sealed container, or that you can continually monitor and detect fluids in a closed pipeline or tank? Well it is possible to do with real-time and spot-check accuracy using Perceptive Sensor Technologies patented technology.

Condition Monitoring with Perceptive Sensor Technologies

The technology was originally developed by the us government to monitor treaty agreements pertaining to chemical weapons, specifically as an efficient way to inspect artillery shells and ensure they did not contain chemical agents. If they did, the sensor also identified the chemical agent inside the artillery shell.

Perceptive Sensor Technologies controls the patented technology and is introducing this technology to the worldwide marketplace to fill an unmet demand to efficiently track and monitor liquid materials. 

Here's how Perceptive Sensors Technologies works:

Just like every person has an identifiable fingerprint, at any given temperature every fluid has a one of a kind acoustic signature fingerprint. When a sound wave travels through a fluid, it produces a unique identifiable measurement. Perceptive Sensors patented science produces an acoustic signal, measures it, and computes the signature to accurately identify the fluid authenticity. This technology offers fast, reliable, and economical inspections. It's easily scalable it works on any sealed container, pipeline, machinery, or system now. Any fluid can be strategically spot-checked or continually monitored to expedite transit, manage product quality, deter theft, and find contraband.

Pyrometer Wavelength Selection Guide

Wavelength Selection
Most single-wavelength infrared pyrometers are virtually identical; however, a close look reveals that most pyrometers are different in one critically important way – the wavelength.

Wavelength is an important parameter when selecting an infrared pyrometer because some optical interferences are highly transparent only in specific wavebands. Infrared energy is an electromagnetic energy just like visible light and x-rays. Visible light does not pass through the human chest while x-rays go right through with wavelength being the only difference. In a similar way, correct wavelength selection allows an infrared pyrometer to view clearly through some types of intervening media, such as steam, flames, combustion gasses, etc., without introducing an error.

White Paper: Integrated Process Control Level Products for the Future

Types of Level Instrumentation

Smarter monitoring facilitates safer, more effective and more sustainable processes, increases uptime and extends service life, irrespective of the industry sector. Behind the scenes, it also helps to keep the infrastructure running efficiently, day-in and day-out. The value of level measurement in this sense can not be overstated whether it is for manufacturing process Measurement & Control or in inventory tank gauging. In applications such as custody transfer, the accuracy of measurements becomes a critical parameter, while in other process industrial applications, along with reasonable accuracy, the safety and reliability parameters are essential to ensuring the overall success of any enterprise. 

In a dynamic environment, the level calculation is difficult with process vessels / tanks that constantly experience changes in the behavior of the measured process fluid due to agitation, mixing, chemical reactions or drained out for downstream processes depending on the application requires. In these systems, these procedures, combined with the fact that they occur at high temperature and/or high pressure, present a safety risk to equipment and staff, which makes the degree of measurement even more important. 

Any inappropriate and insufficient control can cause rates in vessels or tanks to be excessively higher or lower than their safe operating limits, resulting in damage to the machinery, impairing the quality of the final product or causing overflow, and potentially creating safety and environmental hazards resulting in financial losses. 

ABB 's Smart Level Measurement Solutions for Continuous and Point Level Detection can be used to measure a wide variety of liquids, including corrosive, flammable and hazardous materials, while maintaining improved protection, reliability and efficiency at a lower overall cost of ownership for your operations.
