  • The fundamental conductivity and resistivity of water

    Pure water has a very low. but not quite zero, electrical conductivity. This conductivity provides a probe into fundamental properties of water, including the electrochemical mobility of the hydrogen and hydroxide ions. Deviation from this value is a measure of trace ionic impurities. Ultrapure water (UPW). with impurities at or below the sub-parts-per-billion range, is used extensively in many ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • A new categorisation method of resistivity instruments

    This paper presents a new categorisation method of resistivity instrument: Conventional arrays-oriented resistivity instruments (conventional instruments) vs. Comprehensive array-oriented resistivity instruments (comprehensive instruments). The conventional instruments were ...

  • Sorption and resistant desorption of Atrazine in typical Chinese soils

    Atrazine is one of the most commonly used herbicides and is produced and used in large quantity worldwide. In the present study, the sorption and desorption of atrazine in five typical Chinese soils were examined. The sorption of atrazine followed the conventional linear isotherm reasonably well, indicating that sorption was driven largely by hydrophobic partitioning into soil organic matter. ...

  • Superior abrasion resistance demanded by sump cleaning

    Acquired by a open pit mining company located in the Minas Gerais province for a slurry application (up to 60% solids concentration) in a sedimentation sump, the Grindex Bravo 60 pump lived up to its name, proving it's the ideal solution for a wide range of similar installations. In this case ...

  • Pullout Resistance of Steel Geogrids with Weathered Clay as Backfill Material

    The pullout resistance of welded steel geogrid reinforcement embedded in poor-quality, cohesive-frictional backfill material such as weathered clay was investigated. Laboratory pullout tests were conducted on various reinforcement sizes, mesh geometry, and compaction conditions of the backfill material. Field pullout tests were also conducted to investigate the pullout resistance of ...

  • Time-lapse resistivity investigations for imaging saltwater transport in glaciofluvial deposits

    Abstract  Five intersecting resistivity sections have been measured in glaciofluvial deposits hosting an aquifer of regional importance situated along a heavy traffic highway in Sweden. The winter salt spreading has caused a regular salinity increase through the years. For imaging the transport of saltwater in the aquifer, the sections were measured exactly in the same location before and ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • New Advancements for In Situ Treatment Using Electrical Resistance Heating

    Electrical resistance heating (ERH) is proving to be an effective technology to rapidly heat the subsurface and, in doing so, removing volatile organic compounds. Practitioners of this technology have observed that other processes (biodegradation, abiotic degradation, hydrolysis, and possibly others) occur to break down the chemicals of concern, and remediation is not solely accomplished through ...

  • Electrical Resistance Heating: a Hot New Approach to Soil and Groundwater Remediation

    Electrical Resistance Heating (ERH) is an aggressive remediation technology that can quickly reduce the mass of volatile organic compounds (VOCs) in soil and groundwater by over 99%. The process is often used to clean sites where other technologies have had limited success. Larger ERH sites are cleaned within 6 to 12 months and smaller sites can be cleaned in half that time or ...
