  • 5 Specifications to Understand About Reverse Circulation Bits

    5 Specifications to Understand About Reverse Circulation Bits Although wells have been constructed for more than 8,000 years, the concept of reverse circulation drilling was invented in the mid-20th century. It took another few decades until the technology was developed to take reverse circulation drilling from theory to reality. Since the 1990s, however, reverse circulation ...

  • Temperature Compensation and Control

    Alkalinity, pH , and conductivity are just a few of many parameters that are highly affected by temperature. In order to ensure accurate measurements, it is critical to maintain the temperature of the measurement by either a) compensation via mathematical correction, or b) keeping the sample to a constant reference temperature. pH The slope calculated by a pH electrode follows ...

  • EDM Notch

    An electric pulse is a pulse generated by electrons, and a pulse is a process of changing a voltage in a short time. Electropulsing is an unsteady current field generated by a capacitor or an intermittent source. The alternating current we use can be regarded as a pulse current, and one of the cycle processes can be regarded as an electrical pulse. Modern electric pulse technology has developed ...

  • mini LoP improved performance - Case Study

    Meeting very stringent total phosphorous requirements is a challenge for a treatment plant that is receiving wastewater from a dairy process. With a total phosphorous limit less than 100 ppb, a reliable, precise, highly accurate ortho‐phosphorous measurement is required to monitor and control the tertiary phosphorous removal process. Small town plants in the upper Midwest commonly encounter ...

  • Real-time control optimizes extended aeration processes - Case Study

    The population of Hillsborough County, Florida has doubled since the Valrico advanced wastewater treatment plant (AWTP) was built in 1990 to treat the sewage of several small communities west of the City of Tampa. When it began operation, the Valrico AWTP capacity was only 4 MGD; small when compared to Tampa’s 96 MGD Howard F. Curren AWTP located not far to the east. But Valrico serves as a ...

  • Particle Transportation

    Abstract Transportation of particles through tubing between the sample inlet and the optics of a particle counter has often been at the forefront of discussion regarding the truth of readings. With the release of the 2009 EC GMP Annex1 the issue of particle loss of large particles has been elevated such that a better understanding and measurement of those losses is warranted. When the ...

  • What are Core Samplers?

    A core, in marine research, is a cylindrical section taken from sediments underlying a water body. Core samplers, the instruments used to obtain cores, range from the simple to the complex. The variety of corer types reflect the breadth and variety of marine research. For example, the simplest corers are hand-operated types used in shallow waters to collect sediment cores containing fauna. ...

  • Manifold Particle Monitoring: Traditional Limitations

    In traditional manifold systems, a powerful pump pulls air simultaneously from as many as 32 different monitoring locations, with each location as far away as 125 feet. This large cumulative length of tubing, plus the volume of air being moved, requires the pump to create a strong vacuum. As a result, the particle counter samples air from the manifold at a vacuum. The counter no longer draws air ...
