  • Analysis and design of controlled capacitor charging type power frequency inverter

    This paper presents the performance of the capacitor charging type inverters. The inverter uses the voltage and current feedback and produces a desired voltage at the output by suitably charging/discharging a capacitor. An inductor is connected in series to limit the charging/discharging current. Both single and three phase inverters are considered. A small signal analysis is presented to ...

  • Case study: Wireless controlled, four bar lift, indexing charge feeder

    Challenge A unique secondary aluminum producer, located in Kentucky, had recently purchased a more efficient rotary furnace to improve their foundry production. Optimum efficiency requires the furnace doors to be opened and closed in the shortest amount of time to maintain heating efficiency. To feed the new furnace, the current process involved multiple runs using a front end loader to ...

  • Controls on the sorption, desorption and mineralization of low-molecular-weight organic acids in variable-charge soils

    Understanding the controls on interactions between soluble organic compounds and the solid soil matrix is important in understanding soil organic matter dynamics in general, including specific impacts on pedogenic processes, nutrient bioavailability, and C sequestration. This study investigated the pH-dependent relationship between low-molecular-weight organic acids (LMWOAs) and variable-charge ...

  • White Swan Events - Some issues are so common as to be predictable, indeed inevitable… unless competent individuals are in control. Get in charge.

    Abstract With all the facts laid out in hindsight, it is easy to claim that the BP oil gusher was predictable.  It was not.  Disasters of this magnitude are called "black swan" events because they are so rare and unique that they are difficult to imagine and foresee.  That said, the precedents leading up to black swan events follow a well-known pattern. And the processes that ...

  • Design simulation and experimental evaluation of a three-phase controlled capacitor charging type inverter

    This paper presents the design, simulation and experimental verification of a new three-phase pulse width modulated inverter. The inverter works on the principle of controlled capacitor charging, where a capacitor that is connected across the load is charged or discharged in a controlled manner to synthesise a desired waveform. The input to the inverter being a voltage source, an inductor is used ...

  • Study of copper-charged membranes for control of fouling due to bacteria and algae organic matter

    The accumulation of micro-organisms, along with the presence of nutrients, forms biofilms. Biofoulants that are typically encountered in desalination systems include cellular organisms (e.g. bacteria or algae) and organic debris, including algae organic matter. The accumulation of these micro-organisms is problematic to membranes by causing irreversible fouling. The most adverse effects due to ...

  • Controlling acid gas mists

    Gas cleaning New and strict pollution regulations in metallurgical plants worldwide are restricting particulate and acid gas emissions to extremely low levels. Because of that, sulphuric acid plants are being installed to remove and utilise S02 in gases resulting from the roasting of sulphide ores, smelting of ores, and burning or regeneration of spent acid or acid sludge from ...

  • More Power. More Control.

    Cuyahoga County pumps value to its community through greater control, standardization and technological advancements. Cuyahoga County is the most populous county in Ohio, with nearly 1.4 million residents. Part of Greater Cleveland, the county is named after a Native American word meaning "crooked river." With more than 63% of its total area made up of water, the county strives to foster strong ...

  • Controlling Scale Deposition and Industrial Fouling

    It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance ...

  • RO monitors and Controllers: pros and cons

    A look at a range of devices for watching TDS. One major question a potential customer may ask before they purchase a point-of-use/point-of-entry (POU/POE) water treatment system is, “How often will I need to change the filter?” Maintenance and service are directly related to two of their major concerns: money and health. People don’t want to spend money unnecessarily, yet they ...

  • Desalination and water recovery: control of membrane fouling

    Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO) technologies are widely used for the production of safe drinking water, and for the recovery of reusable water from various industrial effluent streams. The most commonly encountered phenomenon in these processes, especially in water recovery application, is membrane fouling, and control of membrane fouling is regarded as a ...

  • 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 ...
