  • The influence of different hydraulics models in treatment of some physical processes in super-critical states of light water reactors accidents

    This work presents the development and testing of some thermal hydraulic models designed to address the limitations of using the Homogeneous Equilibrium Model (HEM) in predicting and simulating the hydraulic response of the positive reactivity-initiated power excursion accidents in small light water reactors. The neutronic response of such accidents has been investigated based on the neutron ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Auto Body Supply

    If there is one tool that is regularly overlooked by auto body technicians everywhere, it's a quality can crusher. One of these useful machines can help you keep your costs down and your shop tidy. A large number of the liquids you use in fixing up and maintaining a car come in steel or aluminum cans. Paint, thinners, lubricants, hydraulic fluids: all of these things come in cans--cans that take ...

  • Coiled Tube Turbodrilling: a proposed technology to optimise drilling deep hard rocks for mineral exploration

    The need to drill deep boreholes more efficiently for mineral exploration has raised the attention to investigate the feasibility of recent drilling technologies for such applications. The two principal methods of Reverse Circulation (RC) and diamond core drilling are usually used in combination by mine operators are subjected to certain limitations and inefficiencies. Considering that delivering ...

  • A genetic algorithm for demand pattern and leakage estimation in a water distribution network

    The sustainable management of water supply networks requires the control of physical pipe leakages, such as those due to junction obsolescence or pipe creeping. These leakages usually increase with the operating pressure, and their discharge is commonly assumed to scale with the power of the pressure. The same functional form is also employed to evaluate leakage occurring in the portion of the ...

  • The New Water Paradigm, human capabilities and strong sustainability

    The ethical power of the New Water Paradigm (NWP) is assessed using a capabilities approach and theory of strong sustainability. The concepts of strong vs. weak sustainability, natural capital, and ecosystem services are explained, and the Old Water Paradigm (OWP) is contrasted with ecological claims at the core of the NWP. The analysis suggests that the NWP should enhance the capacity of ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    The aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw water ...

  • Integration of an analytic element model in a stochastic analysis of infiltration into a complex unconfined aquifer system

    ABSTRACT A hydrologic model based on the Analytic Elements Method (AEM) has been developed for a phreatic aquifer in the General Separations Area (GSA), of the Savannah River Site (SRS), South Carolina, USA. The AEM is a semi-analytical method that relies on the superposition of individual closed-form solutions of elements representing the main hydrologic features of a site. Our study adopts ...

  • Adaptive water distribution networks with dynamically reconfigurable topology

    This paper presents a novel concept of adaptive water distribution networks with dynamically reconfigurable topology for optimal pressure control, leakage management and improved system resilience. The implementation of District Meter Areas (DMAs) has greatly assisted water utilities in reducing leakage. DMAs segregate water networks into small areas, the flow in and out of each area is ...

  • 4 Key Design Criteria for Jet Mixers

    Jet mixers are widely used in both municipal and industrial wastewater treatment facilities to blend the plant influent and suspend light organic solids in circular equalization tanks.  Other applications for these powerful hydraulic mixers include mixing anoxic tanks and anaerobic reactors with the latter application being for industrial waste streams only. Jet ...

  • Skimmer with rolling stand helps prevent oily water discharge

    Despite continuous replacement and upgrading of fittings, it is difficult to entirely eliminate hydraulic and lubricating oil coming from machines during normal operations and maintenance activities. This oil ends up in different pits used to collect wastewater throughout the plant. Because of high oil content, city officials would not allow plant wastewater to enter the Longmont sanitary sewer ...

  • Geodrilling International - Installation of Closed-loop Borehole Probes

    The installation of closed-loop borehole probes is a challenge on almost any project. With many domestic clients requiring a large meterage of borehole to be installed in a small site, Nicholls Boreholes has found that the traditional manual installation of closed-loop borehole probes is no longer a safe or acceptable option. The company has developed the Loop Feeder, a hydraulically-driven, ...

  • Hungarian water companies use British Cranes

  • Oil and water don`t mix

    Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...
