  • Monroe Environmental Saves Steel Mill $145,000 on Clarifier Upgrade and Meets Stringent Performance Requirements

    Challenge A prominent midwestern steel mill needed to put one of its blast furnaces back online in order to increase production and keep up with rising demand. Blast furnace “C”, said to be one of the most efficient blast furnaces in the world for its size, required a large volume of water to maintain proper operation, and the mill’s existing water treatment plant was ...

  • Flow Measurement in the Cold

    Measuring flow can be a very delicate process depending on the needs of your operation. For instance, measuring flow in cold weather locations is an extremely difficult task. When outdoor temperatures are near or below freezing, it makes it nearly impossible to measure flow as you would in normal circumstances, meaning you must find alternative solutions so that your operation continues to have ...

  • Facts About Nested Flumes

    When you need to accurately measure flow in your operation, the best tool that you can choose is a flume. However, there are certain situations where a single flume won’t suffice, such as when you need to measure a range of flows. Fortunately, if you want to measure different flow ranges using flumes, you have the option of using nested, or dual range flumes. ...

  • Parts of a Flume

    In water management operations across the world, the most popular measurement tool is a flume. However, while these tools are commonly used, many people don’t understand the many crucial parts of this complicated device. To get the most out of the flumes in your water management system, it’s important to understand all of the different flume parts and how they work. ...

  • Open Channel Flow Monitors retired after 16 years continuous service - Case Study

    Long Sault WWTP Influent Flow Monitors Greyline Open Channel Flow Monitors were installed at the Wastewater Treatment Plant in Long Sault, Ontario when the SBR plant was originally commissioned in 1995. But after 16 years of continuous service, components for the old models became obsolete. Plant operators Caneau Water and Sewage Inc. decided to replace the instruments and new Greyline OCF ...

  • Area-Velocity Flowmeter Installations in Denmark - Case Study

    Area-Velocity Flow Meters are designed to monitor flow rates in partially filled pipes and open channels without flumes or weirs. A sealed ultrasonic sensor is mounted on the bottom of the pipe or channel and connected to electronics through a watertight cable. The sensor measures both level and velocity and when calibrated with the pipe diameter or channel dimensions, the Greyline AVFM ...

  • Greyline provides end-to-end solution for wastewater treatment plant - Case Study

    Wastewater treatment is a vitally important process. Just ask The Township of Edwardsburgh/Cardinal’s Assistant Chief Water and Sewer Operator, Eric Wemerman. “For a community to keep everyone’s trust, you want to make sure you’re operating a good system.” Eric continues “It’s important for health reasons, when people flush their toilets you need to get ...

  • Velocity-based analysis of sediment incipient deposition in rigid boundary open channels

    Drainage systems must be designed in a way to minimize undesired problems such as decrease in hydraulic capacity of the channel, blockage and transport of pollutants due to deposition of sediment. Channel design considering self-cleansing criteria are used to solve the sedimentation problem. Incipient deposition is one of the non-deposition self-cleansing design criteria that can be used as a ...

  • Measuring Wastewater Below Ground

    Measuring wastewater is one of the most difficult water management tasks that exists. While some wastewater flows are easy to access, others are very hard to measure because they are in open channel conditions and are below grade. If you need to measure below ground wastewater flow, there are a few factors that you need to consider to help you choose the right tool for the job. With a ...

  • Rock Island adult fishway extension - Case Study

    Rock Island Dam is located on the Columbia River, approximately 15 miles south of Wenatchee, WA. The development of a crack in a spillway of Wanapum Dam, downstream of Rock Island Dam necessitated a 25 foot drawdown of the tailrace. This created a significant obstacle for the fish migrating upstream; they would not have access to the original fish ladder. With the arrival of the ...

  • Monitoring accumulation sediment characteristics in full scale sewer physical model with urban wastewater

    A series of experiments were carried out with real wastewater in a pilot flume located at A Coruña wastewater treatment plant (WWTP) (Spain). A full scale model was developed to test a circular (300 mm inner diameter) and an equivalent area egg-shaped plastic pipe under controlled experimental conditions (pipe slope 2–5‰, averaged discharge Q = 4 L/s). Velocity profiles and sediment ...

  • Accurate Flow Monitoring for Billing Applications - Passaic Valley Sewerage Commissioners, Newark, NJ - Case Study

    The accQmin velocity profiling flow meter from Teledyne Isco, Inc. is key to accurate measurement of flow for billing purposes where primary devices such as flumes can be overwhelmed at times of increased flow. Newark, NJ The Passaic Valley Sewerage Commission (PVSC) operates one of the country’s largest treatment plants for the wastewaters of northern New Jersey, working to ...

  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Application of entropic approach to estimate the mean flow velocity and Manning roughness coefficient in a high-curvature flume

    The entropy-based approach allows the estimation of the mean flow velocity in open channel flow by using the maximum flow velocity. The linear relationship between the mean velocity, umax, and the mean flow velocity, um, through the dimensionless parameter Φ(M), has been verified both in natural rivers and in laboratory channels. Recently, the authors of ...

  • Longitudinal dispersion in open channel flow with suspended canopies

    Suspended canopies can cause flow disturbances such as reducing velocities within the canopy, and increasing flow beneath the canopy. Flow modifications by canopies dramatically affect the fate and transport of sediment, nutrients, contaminants, dissolved oxygen, and fauna in aquatic systems. A three-zone model is presented here to predict the longitudinal dispersion coefficient by simplifying ...
