  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • A breath of nothing is decisive: AERZEN Turbo blowers with air bearings provide clear advantages compared to blowers with magnetic bearings

    Aeration tanks for wastewater treatment must be continuously provided with large air volumes. Turbo blowers offer here energy-efficient solutions. AERZEN has developed an amazingly simple method for the fast-rotating Turbo blowers - air bearings. The construction of AERZEN Turbo blowers is quite simple: A blade wheel, aerodynamically optimised and located directly on the motor shaft, rotates in ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • Corporate sustainability: A guide to measuring and improving energy efficiencies

    As environmental scrutiny of global industries continues to grow, governments are seeking to impose energy efficiency targets on companies in order to comply with new directives. One solution is to encourage energy suppliers to become energy service companies, who work with customers to identify potential savings and share the benefits this delivers. For the global food processing industry, this ...

  • On limits for wind power generation

    The amount of wind power in the world increases fast. The background for this development is improved technology, decreased costs for the units and an increased concern of the environmental problems of competing technologies such as fossil fuels. For the future, it is now interesting to evaluate where the limits are for wind power generation, and which points are crucial. Since there is no power ...

  • Biomass power generation in China

    “China is an agricultural country,” said Frank Miao. Farmers used to burn harvest waste, and the government decided to capture this energy by constructing a biomass power plant. At the end of 2006, the total biomass power generation capacity in China was approximately 2,200 megawatts (MW). The planned capacity of biomass power plants is 30,000 MW by 2020. Depending on the size of the plant, three ...

  • Design and Development of a Renewable Cooling and Power Generation Systems

    The key objective of this project is to address the unfulfilled demand for power and cooling in remote, rural, and un-electrified areas and to enhance overall socio-economic conditions through delivery of electricity and improved cold storage facilities using renewable energy. This project seeks to design, develop, and fabricate a number of prototypes with integrated renewable heating and cooling ...

  • Solar power generation by photovoltaic technology

    The various forms of solar energy, solar heat, solar photovoltaic, solar thermal electricity, and solar fuels offer a clean, climate-friendly, very abundant and in-exhaustive energy resource to mankind. Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been under way since the ...

  • Renewable Power Generation Costs in 2014

    Executive Summary The competiveness of renewable power generation technologies continued improving in 2013 and 2014. The cost-competitiveness of renewable power generation technologies has reached historic levels. Biomass for power, hydropower, geothermal and onshore wind can all now provide electricity competitively compared to fossil fuel-fired power generation (Figure ES 1). ...

  • New Generation Small Wind Turbines for Remote Power Systems and Grid Connection

    In this collaborative activity Partners will undertake research and develop economically viable, reliable small wind turbines for remote power systems located away from the electricity grid as well as for connection into the grid. This project will study small wind turbine operation in a wide range of situations, with the goals of improving design, developing safety methodologies and reducing ...

  • An environmentally conscious robust optimisation approach for planning power generating systems

    This study proposes a robust optimisation capacity expansion planning model that yields a less sensitive solution due to variations in model parameters such as demand and fuel prices. By adjusting the penalty parameters, the model can accommodate the decision maker's risk aversion and yield a solution based upon it. The proposed model is then applied to Ontario Power Generation, the largest power ...

  • Programmed PWM to improve power quality in systems with distributed generation units

    Pulse-Width Modulated (PWM) inverters are widely applied in Distributed Generation (DG) units and power quality equipment owing to their excellent performance and flexible control means. Programmed PWM (PPWM), as a special type of optimal PWM strategy, theoretically allows for setting the fundamental and the selected harmonic amplitudes directly to arbitrary values. The algorithms for solving ...

  • Security, trust, and QoS in next-generation control and communication for large power systems

    The present communication architecture supporting control of the electric power grid makes it difficult to use the wealth of data collected at high rates in substations, retarding their use in new applications for controlling the grid. A flexible, real-time data network would make it possible to use these data for many more control and protection applications, potentially increasing the grid's ...
