  • Maintaining a pressure reducing valve: 5 things to check

    Like your car, your body and nearly every appliance you own, control valves require regular maintenance to continue working efficiently. However, due to budget and time constraints, we don’t always give our valves the TLC they need to perform at their best. Unfortunately, ignoring pressure reducing valves can mean serious ...

  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • 99% of Interceptor contamination remediated - Case study

    What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the ...

  • H-ADCP Flow Gauge Installation

    Wessex Water contracted HL to install a new flow-gauge to provide flow data on the environmental impact of abstraction upstream and downstream of a riverside borehole for public-supply. Due to the channel and hydraulic conditions at the site on the River Yeo in Somerset, HL selected a horizontal ADCP Channelmaster device from Teledyne RDi for providing accurate velocity profiles at one elevation ...

  • A moldy summer and the 3 H’S hot-humid-hurricanes

    A HOT WET SUMMER Once again, we’ve entered the hurricane season, when hot humid air envelops most of North America. Beginning in the Spring and lasting until the first frost of Autumn, the air is typically well above 60% Relative Humidity, which is ideal for promoting the growth of mold. The official Hurricane season runs from June to September, and even though they may not qualify as ...

  • Larry H. Miller dealership remodel case study

    In October 2012, the Larry H. Miller Group (LHMG) determined that renovating three of its Peoria, Arizona, dealerships was necessary to remain competitive in the Phoenix market. They embarked on an eight-month-long project that included a complete re-facing of two buildings and a demolishing and rebuilding of the third. The goal of the project was to update showrooms and increase brand ...

  • ENI - 100 m3/h produced water treatment

    Client: ENI Blacktip Field CETCO Oilfield Services is to boost operations in northern Australia, working with integrated energy company ENI after winning a contract worth over $650,000 AUD.

  • Ultrasonic degradation of 1-H-benzotriazole in water

    This paper reports on the effect of different parameters of ultrasonic power, pollutant initial concentration, pH and the presence of co-existing chemical species (oxygen, nitrogen, ozone, and radical scavengers) on the ultrasonic degradation of the endocrine disruptor 1-H-benzotriazole. Increasing the 1-H-benzotriazole initial concentration from 41.97 to 167.88 μM increased the pollutant ...

  • Erratum: Water Science and Technology 72 (7): Development of a new wastewater treatment process for resource recovery of carotenoids, H. Sato, H. Nagare, T. N. C. Huynh and H. Komatsu, doi: 10.2166/wst.2015.330

    A new wastewater treatment process that involves coagulation, ozonation, and microalgae cultivation has been developed. Here, two challenges are discussed. The first was minimizing phosphorus removal during coagulation in order to maximize algal production. The second was to optimize microalgae cultivation; algal species that grow rapidly and produce valuable products are ideal for selection. ...

  • Application of H-infinity hybrid active controller for acoustic duct noise cancellation

    This paper describes the principle and application of a hybrid robust active noise controller (ANC) for reducing broadband noise in acoustic ducts. The proposed ANC system consists of an adaptive controller with filtered-x least mean square (FXLMS) algorithm and a feedback structure with robust synthesis theory for obtaining robust performance and stabilisation. In an active control structure, ...

  • Efficient pre-processing watermark for robust video watermarking of H.264/AVC

    This paper proposes a greyscale pre-processing and robust video watermarking algorithm for the copyright protection application in the emerging video coding standard H.264/AVC. The watermark is first transformed by a Hadamard transform and modified to accommodate the H.264/AVC computational constraints before it is inserted into video data in the compressed domain. This approach leads to good ...

  • An integrated H-infinity optimised fuzzy controller for UPFC in multimachine power systems

    A detailed mathematical model of a multimachine power system with unified power flow controller (UPFC) has been developed with a view to control the active and reactive power flow in the transmission line and to improve transient stability performance. Thus, initial voltage and angles of the series and shunt voltage sources are computed and used during transient stability studies. After the power ...

  • Performance measurement of a twisted three-bladed airfoil-shaped H-rotor

    In the present study, performance of a twisted three-bladed airfoilshaped H-rotor was measured experimentally for different values of chord Reynolds number of flow and ratios of height-to-diameter (H/D). The rotor was 20 cm in height (H) and 5 cm in chord with about 26° twist at the trailing end. Tests were conducted in an open circuit subsonic wind tunnel for ten H/D ratios, namely 0.85, ...

  • Degradation of carbendazim by UV/H 2O 2 investigated by kinetic modelling

    Abstract The transformation of the fungicide carbendazim (methyl-2 benzimidazole carbamate) induced by hydroxyl radical generated by the UV photolysis of H 2O 2 has been studied in dilute aqueous solution. The efficient reaction of hydroxyl radicals with carbendazim led to the rapid degradation of carbendazim. The study of reaction kinetics yielded a second order rate constant of 2.2±0.3 10 9 M ...

  • Simulation of a large multiple pit mining operation using GPSS/H

    As fuel, tyres, maintenance, and labour costs rise, it is crucial that mining companies achieve the greatest production for the least amount of equipment operating hours. Computer simulation can be used to evaluate production operations and their impact on productivity. GPSS/H is one of many computer simulation models that can be used to simulate mining operations. In this study, a simulation ...

  • Observations on an H-shaped dinoflagellate. An example of the projection of body extensions in gymnodiniacean cells

    Little is known about the morphological versatility of the unarmoured dinoflagellates. The morphology of an unarmoured dinoflagellate with a distinctive H-shaped contour is described from sub-surface waters of the Strait of Gibraltar (NEAtlantic) and the northern Philippine Sea (NW Pacific). The cell body was slightly hexagonal with two rounded-tip apical arms and two antapical sharp-pointed ...
