It manages and administers a public river basin of almost 2,000 hectares and a number of more than 200 structures (sluices, weirs, dams etc.). The workforce of 400 employees works in all waterways-related areas in the regions Grand Est and Bourgogne-Franche-Comté. ...
At the trashrack, PHT provided a small P1000 PLC to read in water levels, control the new air blast trash rack cleaning system (by others), and to control and monitor the Limitorque-operated sluice gate at the end of the canal. The controls will detect when the rack needs to be cleaned, and then automatically perform the cleaning sequence by turning off the turbines, opening the ...
Ritakoski is one of the five power plants originally built for Simpele paper mill close to Finnish Russian border. The present power house was built in year 1920 and it was supplied with two vertical francis turbines. Waterpumps WP Oy modernized the plant with four fixed flow compact ...
The original plant consisted of spillover dam, fishsteps, dam sluice, three turbine chambers and generator house behind the chambers. ...
Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferries, rafts, fishways, etc., to achieve their goals. ...
Siltation of the reservoir was a continual issue and required biannual sluicing. The dam was assigned a Significant hazard classification meaning that failure or misoperation of the dam would result in no probable loss of human life but could result in major economic loss, environmental damage, or disruption of lifeline facilities. ...
On Friday, June 11, 2010, a hiker noticed that Testalinden Lake was full and observed water from the reservoir overflowing both the dam and a road along the crest of the dam at the tallest portion of the structure where the sluice pipe was located. The hiker reported his observations at a local tourist information booth (discussed below). ...
To prepare for the Puuloa job, about 750CY of bullet and Pb contaminated soils, TRL undertook an in-place upgrade of the TW10HM. A 36ft 30IN diameter screening plant was added driven by a 7.5hp SEW Eurodrive variable speed mechanical drive. The prior November before the project began in 2008, a preliminary site walk-through was undertaken with the prime contractor and PAC-DIV representatives. The ...
Industries rely on numerous valves in applications ranging from chemical process systems to plumbing, with some of the most common valve types including: Ball valves Butterfly valves Check valves Diaphragm valves Gate valves Globe valves Knife gate valves Parallel slide valves Pinch valves Piston valves Plug valves Sluice valves ...
Summary: A new membrane that’s better for your application Choose Gold-coated polyester membranes for: Detecting and characterizing micro-plastics in environmental water samples. Particle analysis by SEM/EDX, FTIR microscopy and Raman spectroscopy. Identification and characterization of micro- and nanoparticles in pharmaceutical fluids and chemical auxiliary agents. Testing for ...
There are many good reasons for introducing a level of automation to river sluice gates which are old and manually operated. Sluice gates are vitally important for defending against flooding during periods of persistent rainfall, when swift and reliable operation can prevent serious disruption and damage to property. Alternatively, during periods of drought, ...
Traditionally flood protection was the remit of civil engineers designing dams, sluice gates, culverts and dykes. With the decentralisation of government over the years and with the realisation that these civil projects could never feasibly protect all homes at risk of flood damage, a new approach emerged which is based on the principle of protecting individual buildings, ...
The Environment Agency has built two large pumping stations and refurbished a tidal sluice as part of ongoing works to alleviate flooding in the local area. ...
Sluice III in the Wilhelminakanaal near Tilburg is equipped with a Landustrie hydropower screw pump. ...
The irony perhaps is most clinicians are at their most vigilant when in a sluice/dirty utility room setting as they are handling and disposing of infectious material. ...

“These twin policies—the federal tax credit and the state renewable standards—have led to a glut of power sluicing around the sun-soaked Southwest and the windy Great Plains, and have had significant unintended consequences for the market in electric power,” Kavulla said. ...

The larger first-order Markov joint transition probability indicates water quality state Class Vw, Class IV and Class III will occur easily in the water body of Bengbu Sluice. Both marginal distribution and copula models are nonstationary, and the explanatory variable time yields better performance than land cover index in describing the non-stationarities in the marginal ...
Phosphorus (P) forms, with respect to sediment characteristics, and an in-stream sluice were studied in the river–lake system, Huai River catchment area, China. ...
The intended first step was a minor change in the sluice control of the dam that separates the Haringvliet from the sea. However minor, this step was never taken and it is still an ongoing policy debate whether the sluice should be slightly opened or not. This paper presents a coevolutionary analysis of why such a seemingly small change could take so much time ...
This model consists of two hydrodynamic modules: a long wave module (two-dimensional depth-averaged) which includes the analysis of a system of sluice gates, and a wind module (quasi three-dimensional). The model was successfully calibrated and validated with real data, showing its ability to accurately describe the hydraulic dynamics of regulated coastal lagoons. ...
