He invented a novel membrane system that results in higher quality water at a faster rate than conventional membrane systems. The company states that the membrane system has applica- tions in the forestry, oil & gas and mining industries and can increase wastewater treatment without costly and substantial infrastructure upgrades. The proprietary membrane system "separates solids and liquids based on buoyancy allowing for higher production rates and higher quality effluent." A significant characteristic of the membrane system is the added feature of manipulating contaminant buoyancy within the liquid stream allowing the treatment of "a wide range of wastewater types that would otherwise not be re-usable." The membrane is capable of treating high-strength waste, is easily transport- able to remote areas, maintains a small environmental footprint and provides aeration that increases lagoon capacity. TruScan TM Drill Core and Chip Scanner Developed and offered by Boart Longyear, TruScan TM utilizes innovative XRF technology that is specifically built to scan rock. TruScan, the company says, is designed to provide same-day, continuous analysis of drill core or chips and quickly provides non-destructive, accurate, high-density elemental concentration data. TruScan is meant of be used at the drill site or in the core yard to provide geologists with the information they need to decide where to drill next, when they need it and to accurately log drill core. The company explains that, "TruScan uses a unique XRF technology to address textural variations in rock and site- specific calibrations to address the rock type specific matrix effect." The system's accuracy reduces the need to relog core or chip samples and reduces the number of assays needed which lowers the cost of exploration. Because TruScan technology is designed "to fit into the normal workflow of Boart Longyear drill crews there is no decrease in drilling productiv- ity". TruScan is set up and calibrated by a qualified geochemist and can expose geological characteristics that are lost when samples are analyzed using conventional, destructive, analytical methods. Campbell Scientific Based in Logan, Utah, USA, Campbell Scientific makes measurement and control systems for a variety of applications related to weather, water, energy, gas flux and turbulence, infrastructure, and soil. Mining companies employ these devices to monitor slope conditions, tailings dams, air and water quality, mine ventilation among other things. One piece of equipment important to surface mining is a lightning warn- ing system. Campbell Scientific says its lightning warning system measures electric fields, lightning strikes, temperature, humidity and other data that are used to, "trigger shutdowns or evacuations during pre-strike conditions, as well as to identify resume-work conditions when the danger of a lightning strike has passed." The system can text, email or sound an alarm to warn workers in order to keep them safe and prevent equipment damage. Campbell Scientific states that their systems are, "ideal for mining applications because they are versatile, rugged, reliable and designed for harsh, remote locations." The company offers training courses to clients and can customize systems to meet site requirements.
