  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • The Clog Blog

    Clogging and over pressuring are definitely problematic for Liquid Chromatography columns. Back in 2005 John Dolan’s sage advice to chromatographers to make an LC column last forever was simple, “Never open the box!” As John pointed out, this is not practical and I have to agree. But as an LC column manufacturer I have seen remarks from customers regarding clogging as though it ...

  • Controlling the Flow Capacity of a Metering Pump

    Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute Stroke Length ...

  • Detailed dynamic pumping energy models for optimization and control of wastewater applications

    Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant ‘average’ power consumption) are being used in optimization exercises. A new dynamic model for a more accurate prediction of pumping costs in wastewater treatment has been developed to overcome this unbalance in the coupled submodels. The model is ...

  • Fuzzy maximum power extraction control for a photovoltaic water pumping system

    AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...

  • Controlling the addition of Chlorine into a Process

    There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...

  • Principles of Solids Control

    Although the use of drilling fluids within the HDD / trenchless industry is still relatively new, recent trends suggest that this standard is shifting as solids control is one of the most important phases in the drilling process. This shift is due to a growing awareness that drilling fluid maintenance and disposal can become exponential problems as they are both harmful to the environment and ...

  • Industrial Pump Inspection

    An industrial pump service and remanufacturing company had two goals in mind when they went shopping for a borescope. First, the scope had to be easy to use and portable enough to take on service calls. Second, it had to have four-way camera articulation in order to steer navigate the pipes and small through-holes that are commonly found in industrial pump applications. They found exactly what ...
