  • Economics of tiny thermal power plants

    Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...

  • Numerical simulation of drainage scenarios for lowering groundwater rise due to construction of a new barrage on the Nile River

    The government of Egypt constructed a New Naga Hammadi Barrage (NNHB) 3.6 km downstream of the Old Naga Hammadi Barrage (ONHB). Upon construction, the water level raised by about 0.5 and 4 m upstream and within the river reach between ONHB and NNHB respectively. In this paper, a two–layer groundwater model was built using MicroFEM to study the groundwater rising problem. The model was used to ...

  • Power use methods for optimal design of WDS: history and their use as post-optimization warm starts

    This paper describes an extension to the optimal power use surface (OPUS) methodology, which consists of applying a metaheuristic post-optimization process after a network has been designed through the OPUS algorithm. Four different types of metaheuristics were tested in this study. The OPUS methodology focuses on the setting up of efficient ways in which energy is dissipated and flow is ...

  • ARMORMAX® Provides Drop Structure Protection at the Carlota Copper Mine case study

    Water is a precious resource for the Carlota Copper Mine in Globe, AZ, and environmental regulations necessitated zero discharge from mine operations to the nearby Pinto Creek watershed. Construction of new heap leach pads in 2008 dictated the need for a diversion channel to maintain the flow of Powers Gulch without introduction of any leach effluent-Velocities associated with critical and ...

  • Conception and optimization of a membrane electrode assembly microbial fuel cell (MEA-MFC) for treatment of domestic wastewater

    A membrane electrode assembly (MEA) for microbial fuel cells (MEA-MFC) was developed for continuous electricity production while treating domestic wastewater concurrently. It was optimized via three upgraded versions (noted α, β and γ) in terms of design (current collectors, hydrophilic separator nature) and operating conditions (hydraulic retention time, external resistance, aeration rate, ...
