  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • The key advantages of FlashRES resistivity meter

  • Panama Canal: Boat Towed 3D Resistivity Surveys - Case Study

    The Panama Canal Authority (ACP) needed to expand the canal in order to accommodate larger ships (and more traffic)—but first, they needed to know two things: what types of sediment loads needed to be dredged out—and more importantly—how much these loads would cost. That’s where AGI marine resistivity imaging ...

  • High efficient Mise-a-la-Masse case study

    The traditional Mise-a-la-masse technique has a terribly reputation in its efficiency, however it is a good tool to seek the developing direction of the ore body.  For example, to measure 128 voltages for one current position, operator needs inject current into ground 128 times, where the system will measure the voltage potential 128 times. If done manually, this can be very time ...

  • Identification of Archeological Remnants

    Czorsztyn Castle, Poland 2D Electrical Imaging Objective Study area was within the ruins of the 14th century Czorsztyn Castle, located in the boundaries of Pieniny National Park (southern Poland). The main goal of this research was to check if one of the stone wall residues continues under the ground surface. Additionally, an attempt was ...

  • Application of radiomagnetiotelluric method case study

    Investigations of the landfill of industrial wastes by the RMT method The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The ...

  • Searching for Archeological Anomalies in the Oluz Mound - Case Study

  • Estimating soil conductivity for GPR surveys

    The results of a ground penetrating radar survey depends on many factors. In order to get useful data and good penetration, one of the conditions is that the conductivity of the ground is not too high. The conductivity of the material together with the operating frequency and the dielectric constant allow us to calculate the loss factor that is used to roughly estimate the theoretical ...

  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • Size Reduction of Technical Plastics– Two-Stage Operations more Efficient than Single-Stage

    At HKR Kunststoffe GmbH in Langenbeutingen, technical plastics such as ABS, PBT, PC, POM, but primarily PA 6, PA 6.6, PA 12, PPA, LCP, etc. – particularly glass fibre reinforced types – are processed into high-grade regranulate. These materials accumulate as production waste in the plastics processing industry in the form of start-up chunks, sprues, rejects, etc. They are treated in two-stage ...

  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...
