  • ETLS pumps for Valemon oil production field - Case Study

    The Valemon oil production field offers recoverable oil and gas reserves, estimated to be approximately 26 billion m3 of gas and 31 million barrels of condensates, which makes it one of the biggest undeveloped gas fields in the North Sea. Cameron Ltd, one of the chosen contractors for the project run by Statoil, approached Rodelta as one of the few suppliers that was able to meet the stringent ...

  • Research on CFD numerical simulation and flow field characteristics of countercurrent–cocurrent dissolved air flotation

    Countercurrent–cocurrent dissolved air flotation (CCDAF), the popular water purification device, which consists of collision and adhesion contact zones, showed favorable flotation conditions for micro-bubble adhesion and stability. In this study, computational fluid dynamics (CFD) numerical simulation was employed to confirm that the unique CCDAF configuration create reasonable and that the ...

  • VENTUS-X-UMB field test in Norway - Case Study

    In a project, launched in January 2016, the Norwegian airport systems integrator Avinor has tested a new VENTUS-UMB model with an enhanced heating power. Two of the new models have run in the field, installed at the most extreme sites in Norway, where they are delivering wind data reliably ever since their installation. One is placed at the top of Kjølen mountain, close to Tromsø ...

  • Biofiltration field study for cold Fe(II)- and Mn(II)-rich groundwater: accelerated Mn(II) removal kinetics and cold-adapted Mn(II)-oxidizing microbial populations

    Removal of Mn(II) from Fe(II)- and Mn(II)-rich groundwater in cold regions is challenging, due to slow Mn(II) removal kinetics below 15 °C. This study demonstrated onset, acclimation, and acceleration of Mn(II) removal in a two-stage pilot-scale biofilter (Fe and Mn filters) at varying low on-site temperatures (8–14.8 °C). Mn(II) removal commenced at 8 °C in the Mn filter after Fe(II) removal. ...

  • Field study on N2O emission from subsurface wastewater infiltration system under variable loading rates and drying-wetting cycles

    In this field study, the impacts of influent loadings and drying-wetting cycles on N2O emission in a subsurface wastewater infiltration (SWI) system were investigated. N2O emitted under different operation conditions were quantified using static chamber and gas chromatograph techniques. N2O conversion rate decreased from 6.6 ± 0.1% to 2.7 ± 0.1% with an increase in hydraulic ...

  • Axetris Sensor Field Test

    The Axetris LGDs were operated continuously for two years. After intensive laboratory testing, they went out into the field in 2015. Axetris was able to test the functionality of its sensors under real-life conditions thanks to the support of the Linth waste incineration plant. The gas concentration measuring devices called laser gas detectors ( ...

  • Ecology of duckweed ponds used for nutrient recovery from wastewater

    The microorganism community that grows under duckweed shelter can play an important role on treatment processes. Therefore, the present study aimed to assess the zooplankton dynamic and microbial community in duckweed ponds (DPs) applied for domestic wastewater treatment under open field conditions. A pilot system comprised of two DPs in series (DP1 and DP2), with 10 m2 each, received domestic ...

  • Dynamic simulation of sediment resuspension and its effect on water quality in Lake Taihu, China

    Quantitative studies on sediment release fluxes and their impact on water quality are important for water pollution control, ecological restoration, water safety, and human health. In this study, we conducted high-frequency, synchronous field observations of meteorology, hydrology, and water quality to determine the relationship between sediment release rate and wind speed in the central ...

  • Liquid-gas mass transfer at drop structures

    Over the last decades, considerable progress has been made in the understanding of the sulfur cycle in sewer systems. In spite of a wealth of experimental and field studies that have addressed the release of hydrogen sulfide from free surface flows in gravity sewers and the corresponding air-water mass transfer, little is known about hydrogen sulfide emission under highly turbulent conditions ...

  • Groundwater discharge downstream of an arid inland river in Northwestern China

    Nalenggele River is an inland river located in the arid, fragile ecological environment area in Northwestern China. Groundwater discharge to the river can significantly impact the ecologic environment in the Nalenggele River basin, but few hydrogeological studies have been conducted in the inland arid basin. In this paper, two sections were chosen to analyze the groundwater discharge in the ...
