WASTEWATER FLOW CONTROL RESOURCES

  • 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.

  • Existing level monitoring, usually for combined sewer overflow (CSO) or event duration monitoring (EDM) purposes has been in regular use in the U.K. for over a decade, but the equipment hasn’t changed much in that time. With the current technology comes limitations. So, the question Dave Walker, co-founder and commercial director at wastewater monitoring specialists Detectronic, has been asking is: How can we do level monitoring better for the benefit of water companies, their customers, and the environment?

  • With freshwater sources depleting rapidly, treating and consuming wastewater seems to be the only option in the near future. As per a UN population fund released in 2001, it was estimated that the world will start facing water-related issues by 2050.

  • The City of Warren Water Recovery Facility in Michigan, treats and protects the waters of the state. Proper water treatment is the main goal for the City as it has a direct impact on the future, ecosystem and providing residents safe and clean water to drink and participate in outdoor activities. Read the full case study to learn how the City of Warren Water Recovery Facility has been able to attain accurate data at a high repeatability rate since the installation of the Promag W unrestricted mounting 0 x DN electromagnetic flowmeter.

  • Level monitoring systems has successfully triumphed every implementation. Their deployments allow the users to measure the level of liquid stored in a container of any shape, size, orientation, or material. Powered with the advanced telemetric technology of Internet of Things, these systems measure liquid level without making any contact with the liquid and transmit the readings to a comprehensive platform suite.

  • Today, the world is facing unprecedented circumstances that are affecting every single sector and the water service is no exception. Although there is still more research to be done, this article has collected the currently available information to highlight how wastewater utilities have been affected by the COVID-19 pandemic. More specifically, this article will attempt to look at the outbreak’s impact on utilities, the potential hazards, and the predominant solution.

WASTEWATER FLOW CONTROL MEASUREMENT SOLUTIONS

  • 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.

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.
