WASTEWATER FLOW CONTROL RESOURCES

  • This presentation will focus on converting and expressing flow rate gallons in minutes, converted from flow rate gallons in hours.

  • Klargastechnik Deutschland GmbH is a leading bioengineering, designer, manufacturer and installer of biogas and disgester gas processing equipment and systems that is headquartered in Germany. The company’s products include all-welded gas storage tanks, flare systems, dry and biological desulphurization systems, explosion proof (ATEX) certified blowers, gas drying units, filters and accessories.

  • The City of Memphis teamed with Brown and Caldwell to pilot a smart sensor network where water-quality monitors could be installed directly at permitted discharge points for five of the largest industrial users. The pilot project also served as a proof-of-concept project for the City to assess the feasibility of making a paradigm shift to digital water-quality monitoring as a long-term solution.

  • The Metropolitan Waterworks Authority (MWA) produces and supplies drinking water to over 11 million people in the Bangkok Metropolitan area covering the provinces of Bangkok, Nonthaburi, and Samutprakarn. On average, around 5.47 million cubic meters of water gets distributed daily through a network of pipelines spanning 37,700 kilometers.

  • Water Online’s “Math Solutions Explained” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), educates operators by explaining pipe volume gallons calculations.

  • The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system. 

  • Wet weather is a continuous concern for wastewater utilities. Rain-derived infiltration and inflow (RDII) challenges the collection system capacity. It can potentially result in overflows in the collection system and even the wastewater recovery facility (WRF) in extreme cases. These overflows can threaten public health and the environment. Additionally, higher flow volumes associated with wet weather will increase operating costs at the WRF.

  • Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.

  • The City of Decatur Wastewater Treatment plant in Texas includes a polishing pond and effluent discharge basin, both of which can be overcome with algae growth depending on weather and environmental conditions throughout the year. At times, the algae overgrowth would plug areas of these systems and restrict or block the flow from the polishing pond and effluent basin, which sit approximately 300 yards from each other.

  • In industry today, everyone is looking for ways to conserve a bit of energy and save some money. For instance, consider the energy consumption across the United States just in the water treatment process. With thousands of public water utilities, the amount of energy usage is significant.

  • Proline Promag W 400 Electromagnetic Flowmeter

    The Proline Promag W 400 electromagnetic flowmeter is a versatile standard flowmeter for the water and wastewater industry.

  • Battery Powered Dura Mag™ Flow Meter

    The Dura Mag is an ideal solution for nearly any water manager. With a five-year battery life (and three-year battery warranty), the Dura Mag eliminates the need for AC power connection, and provides the easiest installation available on the market for a flanged mag flow meter. In addition, the Dura Mag comes equipped with an internal datalogger with five years of data storage to ensure you always have access to your historical data. The Dura Mag also has several telemetry-ready output options, and the converter settings are USB port accessible which eliminates accidental setting changes.

  • Process Optimization For Flow Measurement

    The Saalfeld-Rudolfstadt Association in Germany is committed to supply around 82,000 inhabitants with clean drinking water. The resulting wastewater must be cleaned and disposed of to enable a closed water cycle. To allow for smooth processes, the customer relies on cutting-edge technologies to optimize flow measurement.

FLOW CONTROL AND MEASUREMENT

 

Flow measurement can be defined as quantification of the movement of water in a given channel. Flow can be measured either by determining the displacement and/or Velocity of the water. Water meters usually control measure and display total usage in cubic meters, on either mechanical or electronic registers. 

Flow can be divided into two main flows which are: Open channel flow and Closed conduit flow. Flow is controlled by use of valves at intervals to either to slow down, allow faster flow or completely shut down the flow. Some water meters usually perform both the function or making readings and controlling flow while others just conduct measuring only. 

Meters for reclaimed water contain special lavender register covers show that the water is non-potable. Velocity-type meters measure the velocity of flow through a meter of a known internal capacity. The speed of the flow can then be converted into volume of flow for usage. Since Multi-jet meters are usually very accurate in small sizes they are normally used for residential and smaller commercial uses. Turbine meters are not as accurate as jet meters and displacement meters at low flow rates. 

A compound meter is used where high flow rates are necessary. Magnetic flow meters are a velocity-type water meter, except that they use electromagnetic properties to determine the water flow velocity. In water treatment plants, measurement and control devices can be installed in the following locations: within interceptors or manholes, the head of the plant, in the force mains that lead to main tanks etc. Automatic Meter Reading has compelled producers to build pulse or encoder registers to provide electronic output for radio transmitters, reading storage devices, and data logging devices.
