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. Here are a few ...

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. Nested flumes are a ...

Food Processor Flume Cleaning Wastewater Case Study
Food Processor Flume Cleaning Flume Cleaning with Rotary Screen Flumes that are used to transport food from the trucks or storage facilities (tomato, potato, carrot processing) build up with settled solids as the product is conveyed along the flumes. Over time, these solids reduce the flow rate in the flumes and need to be cleaned out to maintain the same product ...

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 ...

Potato Flume Water 1
This client transports potatoes from their receiving dock to the processing area of the plant in a water flume. This process removes the dirt from the fields. The pH was 6.3 and did not require pH adjustment. The sample was tested with I, H, and K and it was determined that the K was the best product for clarity, reduced dosage and floc size. The samples were treated with 0.13 grams of Floccin-I, ...

The historic water system of mission San Diego de Alcalá, San Diego County, California.
The Old Mission Dam and Flume is an historically significant system of water control structures on the San Diego River, San Diego County, California. The most conspicuous remnant of the system, Old Mission Dam, is located at the head of Mission Gorge in the western corner of El Cajon valley, about six miles upriver from Mission San Diego de Alcalá. This system, designed and built from the late ...

Metalworking reclaim saves $400,000 annually
The Problem: A Detroit, MI based transmission component supplier was using an extremely large amount of metalworking concentrate. The supplier had 48 independent cutting machines, with a total sump capacity of approximately 13,000 gallons. For these machines, there was an extraordinarily high use rate of coolant product, sometimes reaching as high as 9,000 gallons per week of coolant ...

Old mission dam and flume: preliminary findings of new research on the waterworks system of mission San Diego de Alcalá, San Diego County, California.
The Old Mission Dam and Flume is an historically significant system of water control structures on the San Diego River, San Diego County, California. This system, designed and built from the late 1700s to the early 1800s by Franciscan missionaries and Kumeyaay Indians associated with the Mission, was intended to provide a reliable year-round supply of water to Mission San Diego de Alcalá and to ...

Nitrogen Fate in drainage ditches of the coastal plain after dredging
Received for publication June 14, 2008. Drainage ditches are a key conduit of nitrogen (N) from agricultural fields to surface water. The effect of ditch dredging, a common practice to improve drainage, on the fate of N in ditch effluent is not well understood. This study evaluated the effect of dredging on N transport in drainage ditches of the Delmarva Peninsula. Sediments from two ditches ...

Verification of equations for incipient motion studies for a rigid rectangular channel
The current study aims to verify the existing equations for incipient motion for a rigid rectangular channel. Data from experimental work on incipient motion from a rectangular flume with two different widths, namely 0.3 and 0.6 m, were compared with the critical velocity value predicted by the equations of Novak & Nalluri and El-Zaemey. The equation by El-Zaemey performed better with an ...

Evaluation of overland flow model for a hillslope using laboratory flume data
Comprehensive modelling of overland flow requires models for both rill and interrill area overland flow. Evaluation of a physically based mathematical model for simulating overland flow generated on rill and interrill areas of hillslope was done using a data set gathered from a laboratory experimental setup. A rainfall simulator has been constructed together with a 6.50 m × 1.36 m ...

Sediment deposit thickness and its effect on critical velocity for incipient motion
The understanding of how the sediment deposit thickness influences the incipient motion characteristic is still lacking in the literature. Hence, the current study aims to determine the effect of sediment deposition thickness on the critical velocity for incipient motion. An incipient motion experiment was conducted in a rigid boundary rectangular flume of 0.6 m width with varying sediment ...

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 ...

Potato Flume Water 2
The facility was paying to have their water hauled off site as a means of disposal. The facility was using an average of 20,000 gallons/day of fresh water to operate the flume system used to transport the potatoes from the dry storage sheds to the processing room. The flume sump would fill up with solids and required weekly cleaning. The settle dirt and organic material created a bad odor and an ...

Marshall, MI Site 3 - Case Study
Location: Marshall, MI Cofferdam Sizes: 9′ wide x 500′ long flume tube Water Depth: 2-3′ Installation Time: 3 hours Project Description: Route clean water around massive oil spill. In recent years, oil spills and improper wastewater discharges have become a huge environmental concern. Quick action is required to mitigate damage and promptly ...

Experimental assessment of Athabasca River cohesive sediment deposition dynamics
Polycyclic aromatic hydrocarbons (PAHs) originating from natural sources, and potentially from the Athabasca Oil Sands development, are of concern for the Athabasca River and Lake Athabasca delta ecosystems. In order to model the transport of fine sediments (and associated PAHs), it is important to describe the sediment dynamics within the river system. Flocs possess different settling ...

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 little ...

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 ...
