  • Focus on Microfiltration Part 3: Extending Service Life Using Prefiltration

    Last month we examined filter selection strategies for maximizing service life in continuous use applications.  In this 3rd installment, we will examine the use of prefilters to extend service life. Clarifying liquids with high levels of suspended solids is challenging, especially for applications requiring submicron filtration.  In these applications, filter users who experience ...

  • Resistivity system voltage output

    One limit of FlashRES resistivity meter is its voltage output. It can output maximum voltage of 350v, this is because the multi-core cable of the FlashRES cannot withstand voltage over 350v. the multi-core cable contains 32 small wires, voltage higher than 350v will damage these wires and make the cable short circuit. We thus limit the maximum voltage output for safety reasons. Reference ...

  • Multidrug resistance in fungi

    One of the major advances serving to define the beginning of the era of modern medicine was the development of penicillin in the early 1940s as the first widely used antibiotic effective against microorganisms (reviewed in reference 111). In what has become an all-too-common trend, antibiotic-resistant isolates emerged soon after the large-scale use of penicillin to treat bacterial infections ...

  • Fiction EHC fluid resistivity

    Since the mid 1960's turbine hydraulic fluid systems have been using Fire Resistant Fluid (FRF) to control their turbine inlet valves. It is a known “FACT” that low fluid resistivity adversely affects the internal components of servo valves within the hydraulic fluid system. Root cause analysis studies conducted by numerous agencies have determined ...

  • Proliferation resistance and the nuclear renaissance

    Currently, nuclear power provides 16% of the world's electricity, using 439 reactors in 30 states and in Taiwan, China. This paper explores how emphasising proliferation resistance can guide decisions allowing increasing use of nuclear power without challenging international security. It reviews the definition of proliferation resistance and describes how proliferation resistance for a given fuel ...

  • HDPE - A Hydrocarbon Resistant Membrane?

    Most brownfield redevelopment and environmental protection applications require the use of a hydrocarbon resistant membrane.  However, each membrane material will vary in its ability to resist chemical attack and its effectiveness as a barrier to permeation.  It is essential that a barrier material prevents the migration of contaminants, thereby not harming the surrounding environment ...

  • Flame Resistant Clothing

    Flame resistant (FR) clothing is designed as a means or protection against potentially fatal flash fire and arc flash environments.  The main source of fatal and serious burn injuries are usually due to the igniting of an individual’s clothing.  Flame resistant clothing allows precious time for the person wearing the clothes and also helps to prevent clothing ignition.  Keep in ...

  • A history of chemically resistant membranes

    The use of polymeric membranes for filtration of non-aqueous solutions started around 1960 and has been developed significantly since then [1]. Today, non-aqueous membrane filtration applications in chemical and pharmaceutical processing account for more than 25% of the global total polymeric membrane market [2]. ...

  • Roll along resistivity survey

    A roll-along survey is a method for operator to survey a long line. After the initial survey, the operator will leave one cable on the ground and move the instrument and cables forward. So there is always one cable overlap between two surveys. Alternatively, the operator can divide the cable in half and only overlap 16 electrode spacing. In this way, the opearator could complete the survey ...

  • 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 ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • The exploration depth of FlashRES resistivity meter

    The formula for calculating the maximum depth is universal for all resistivity meters. The exploration depth depends on the survey line length. the survey depth is usually 20-25% of the survey line total length. For example, for 10m takeout cables, the total length of the cable is 10m*63=630m and this means the exploration depth is 0.2*630m to 0.25*630m. The resolution is 10% of ...
