  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Repeatability is King: Up to Tenfold Improvement

    Axetris has improved the repeatability specifications of its mass flow meters and controllers. Repeatability often more important than absolute accuracy Repeatability provides information about the precision, that is, the absolute difference between a pair of repeated test results measured by one instrument under unchanged conditions. To measure precision, the same ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • New technology for municipal scale compost operations

    There is a new facility located in Ontario, Canada that accepts construction and demolition waste (C&D) and 100,000 TPY of source separated organics (SSO) waste. The owners chose a new non-thermal plasma (NTP) system to control the odor in its 120,000 cubic feet of air per minute (CFM) air emissions. 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 ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • 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 ...

  • Small-scale electricity production from biomass

    NC Service has set up the first plant of this type in Spain Thanks to the BIOCOM Project, Nicolás Correa Service, S.A. has built the first biomass combustion plant that not only produces thermal energy, but also electricity on a small scale (130 gross kWe). The process is based on the combustion of woodchips in a furnace to produce heat that is then transferred to an ORC module, where it ...

  • Specification and calibration requirements for industrial scales in pharmaceutical applications

    Introduction Performance and accuracy of industrial scales in pharmaceutical applications are covered by current Good Manufacturing Practices (cGMPs). Verification of proper operation of process scales is an important factor in finished product Quality Assurance (QA) programs. Incorrect weighing, additions of materials and components in validated processes of formulation, dispensing, and ...

  • A dynamic virtual power station model comprising small-scale energy zones

    Concerns over global warming and high oil prices are expected to lead to a continuous increase in electricity generated by distributed renewable energy sources and small-scale embedded generators (SSEGs). This increase in SSEG will pose numerous technical challenges for distribution network operators. The small-scale energy zone (SSEZ) concept seeks to overcome these challenges using appropriate ...

  • Full-scale SVE system operates in tandem with groundwater treatment

    Since 1993, SVE has been implemented using two designs at the TP Industrial, Inc. (TPI) site in Gardena, CA, to treat soil contaminated with chlorinated solvents. The SVE system was modified in 1997 to improve emissions control efficiency by using carbon adsorption units that treat effluent from an air-stripping system for treating site ground water. By the end of 2007, SVE had removed a ...
