  • Predictive Analytics Will Be Critical to Beating the Driver Shortage

    The number of people working in the U.S. trucking industry hit an all-time high in December: 1.47 million, according to the U.S. Department of Labor. That’s impressive — and great for the industry — but in no way does it eliminate the intense, industry-wide concern about and focus on the enormous projected need for more drivers every year through at least 2030.  ...

  • Measuring IR Light and Near-IR Light

    Infrared (IR) light emits a broad range of non-visible wavelengths in the electromagnetic spectrum. Applications for infrared, including near-infrared, are defined by the respective IR bands during output. For example, LIDAR (Light Detection and Ranging) equipment uses 1,000 nm and 1,550 nm IR bands while surveying an area. In the military sector, 850 nm, 1,060 nm and 1,500 nm (and up) are used ...

  • Santa Cruz Meets THM/DBP Challenge with Unique Air Stripping Process - Case Study

    Summary Santa Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. The City evaluated various aeration treatment processes and chose an E-Z ...

  • An approximate model on three-dimensional groundwater infiltration in sewer systems

    Groundwater infiltration through cracked sewer pipes has caused significant economic losses. This paper presents a three-dimensional analytical expression for calculating the steady-state groundwater infiltration rate into sewer systems. As an extension of the previously developed two-dimensional model by the author, this new model can be used to simulate the infiltration through an orifice ...

  • Combined process of electrocoagulation and photocatalytic degradation for the treatment of olive washing wastewater

    In this study, an electrocoagulation reactor (ECR) and photocatalytic reactor (PCR) were tested to understand the performance of combined electrocoagulation and photocatalytic-degradation of olive washing wastewater (OWW). The effects of initial pH (6.0, 6.9, 8.0, 9.0), applied voltage (10.0, 12.5, 15.0 V), and operating time (30, 60, 90, 120 min) were investigated in the electrocoagulation ...

  • Utilizing analytic hierarchy process (AHP) for decision making in water loss management of intermittent water supply systems

    Increasing water demands, in parallel with water scarcity, force water utilities in developing countries to follow complex operation techniques for the distribution of the available amounts of water. The reduction of water losses from water supply systems can help fill the gap between supply and demand. This strategy is characterized by the variety of options, and identification of the most ...

  • Evaluation of virus reduction efficiency in wastewater treatment unit processes as a credit value in the multiple-barrier system for wastewater reclamation and reuse

    The virus reduction efficiency of each unit process is commonly determined based on the ratio of virus concentration in influent to that in effluent of a unit, but the virus concentration in wastewater has often fallen below the analytical quantification limit, which does not allow us to calculate the concentration ratio at each sampling event. In this study, left-censored datasets of ...

  • One step, low pH iron and organics removal - Case Study

    Review For over seven years, the semiconductor facility performed routine on-site cleans of their reverse osmosis (RO) membranes using RoClean P111 with good results. However, over a six month period in 2015, membrane cleaning frequency increased to once a month and permeate flows could not be sufficiently restored. An Avista application specialist visited the site to personally monitor the ...

  • Samsung’s New Safety Truck Technology

    In Argentina, one person dies in a traffic accident every hour – 80% of these fatalities are caused by drivers trying to overtake other vehicles. With hundreds of one-lane roads in the country, drivers often get frustrated by slower moving semi-trucks ahead of them and will try to pass them despite not being able to see on-coming traffic. Samsung saw a solution to this problem. By ...
