  • Reasons You Should Invest in an Arsenic Water Treatment System

    In many areas of the U.S., the element arsenic makes its way into the water supply. This element can have adverse health effects. Although it’s rare that it shows up in large enough concentrations to be fatal, it can still cause problems and should be eliminated. Health Effects Many studies have been done to determine the specific effects of consuming water ...

  • 5 Reasons to Use Eductor Systems for Complex Rehabilitation

    Rehabilitation of dams and levees present complex geotechnical conditions. Contractors require dry, safe and stable working environments in order to carry out an effective rehabilitation project. As our national dam and levee infrastructure ages, the pressure to stabilize construction sites and lower costs will rise. Eductor systems provide a safe, cost-effective dewatering solution for these ...

  • The Modular Building Construction Process: A 5-Step Guide

    Many people are turning to modular buildings as an affordable and efficient space solution. Since they are built off-site in sections, they make it easier for people to get into their building quickly while other aspects are being built around them.

  • Raising Dead Ships: Derelict Vessel Removal

    One of Global’s specialties is vessel salvage – if your vessel runs aground or sinks, we’ll raise it and hopefully refloat it for you. But what happens to the thousands of old, worn out vessels that sit abandoned along the coasts and harbors? Often they sink, where they pose an environmental and navigational hazard. That’s why Washington, Oregon, California and Alaska have ...

  • Mining Waste, more than just camp waste - Case Study

    Mineral extraction adopts the very latest technology and operational methods and the waste aspect is a high agenda item that Inciner8 solves within mining compounds. Uncluttered, efficient operations with active heavy plant and machinery demand that waste solutions are present to clear, clean and deliver a consistent solution in many 24x7x365 mining operations.

  • Mobilization assessment and possibility of increased availability of PAHs in contaminated soil using column tests

    Surfactants are well known to increase solubility/mobility of hydrocarbons and can be used to remediate contaminated water and soil. We wanted to explore if Ivey sol R   106 used at less than the critical micelle concentration (CMC) could effectively mobilize PAH (polycyclic aromatic hydrocarbons) from contaminated soil. The first step was to establish a measurement technique. Hence, a ...

  • Biofiltration field study for cold Fe(II)- and Mn(II)-rich groundwater: accelerated Mn(II) removal kinetics and cold-adapted Mn(II)-oxidizing microbial populations

    Removal of Mn(II) from Fe(II)- and Mn(II)-rich groundwater in cold regions is challenging, due to slow Mn(II) removal kinetics below 15 °C. This study demonstrated onset, acclimation, and acceleration of Mn(II) removal in a two-stage pilot-scale biofilter (Fe and Mn filters) at varying low on-site temperatures (8–14.8 °C). Mn(II) removal commenced at 8 °C in the Mn filter after Fe(II) removal. ...
