  • 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 ...

  • The vibration monitoring evolution

    A recent report from Markets & Markets estimated that demand for vibration monitoring systems will reach nearly $1.5 billion by 2020. That’s a staggering increase of around 50% compared with today – with a compound annual growth rate (CAGR) of more than 6.5%. Is this growth a big surprise though? As a company that has seen first hand the rapid evolution of the ...

  • Comparison of simple ozonation and direct hydrogen peroxide processes in TNT removal from aqueous solution

    Oxidation of 2,4,6-trinitrotoluene (TNT) using simple ozonation and direct hydrogen peroxide was studied. An analytical method based on the HPLC (high performance liquid chromatography) system was used for TNT detection. The influence of parameters such as pH of the solution (3–10), initial TNT concentration (10–100 mg/L), dosage of ozone (0.2–1 g/hr), H2O2/TNT molar ratio (250–1,000), ...

  • 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 ...
