This NTP system is very compact, fits easily on a platform, is configured as a number of ...

  • Controlling scale deposits in the pulp & paper industry

    The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product.  As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...

  • Optimal control model of technology transition

    This paper discusses the use of optimisation software to solve an optimal control problem arising in the modelling of technology transition. We set up a series of increasingly complex models with such features as learning-by-doing, adjustment cost, and capital investment. The models are written in continuous time and then discretised by using different methods to transform them into large-scale ...

  • Preventing scale in recreational vehicles and motorhomes

    Over 80% of North America is affected by hard water, which is a major problem for the owners of RVs and Motorhomes.  Consequently, whatever State you are visiting in your RV, or if you have a motorhome permanently located in a hard water area, limescale will clog pipes, ruin appliances, destroy faucets and cloud glassware. The award-winning, patented, Scalewatcher water-conditioner, from ...

  • Would a two-stage N-removal be a suitable technology to implement at full scale the use of anammox for sewage treatment?

    Sewage treatment with anammox could be implemented through a two-step reactor system, where the first reactor would be devoted to partial nitritation. A process design was sketched including control loops. The control strategy regulates the flow-rate of the rich ammonium sidestream produced after dewatering the digested sludge, to keep the ammonium concentration at a set point in the partial ...

  • Managing large–scale science and technology projects at the edge of knowledge: the Manhattan Project as a learning organisation

    Few projects have had such a profound and lasting effect on the world as the Manhattan Project. Today, after it was approved 70 years ago by President Franklin D. Roosevelt, its legacy is felt in nuclear medicine, military defence, terrorist threats, and the production of energy. What was remarkable about this project was that to succeed it had to push through the frontiers of knowledge in ways ...
