  • Case-Study: Emission Monitoring in Tunnel Using Polludrone

    With the massive influx of Pilgrims to Mecca every year, the Abdul Aziz Tunnel in Jeddah faces excessive pollution during the holy month of Ramadan. The authorities thus had to equip the tunnel with air monitoring devices to monitor the pollution level. Oizom stationed Polludrone throughout the tunnel to observe the vehicular emission. The analyzed data helped the authorities to identify the peak ...

  • Statistical Corrections Microbial Monitoring in Grade C/D Cleanrooms

    Microbiologists rely on the Feller table to correct for undercounting of biological activity. The “Table of statistical corrections according to Feller” is based on the principle that as the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. This table is ...

  • Flow metering with MaxxFlow HTC - Case Study

    Application An important part of the production of cement is the processing of raw meal in the cyclone dust heater. During this process cement meal is heated by an airstream. Thereby CO2 is extracted from the cement. At the beginning of this process raw meal is stored in a silo, from where it is discharged via an air slide into a bucket elevator. The bucket elevator ...

  • Air Volume Change Measurement in Unsaturated Soil Testing Using a Digital Pressure-Volume Controller

    One of the challenges associated with the testing of unsaturated soils is the measurement of air volume change induced by stress changes. This paper reports the results of an evaluation of a digital pressure-volume controller as an air volume change indicator. Effects of temperature, confined volume, and precompression of the measurement medium on the p-V characteristics and the device response ...

  • Is the Rotameter Ready for Retirement in Air Sampling/Monitoring Applications?

    The variable area rotameter has been the primary tool utilized for determination of flowrates passing through the air circuitry pathway of air sampling or air monitoring systems for many years. In air sampling applications a pollutant is captured on a collection medium (filter paper, charcoal cartridge, etc.) and taken to a laboratory for determination of the quantity of pollutant on the ...

  • Modern Technology Closes the Gap caused by the Deficiencies in Traditional Analog Air Sampling Instrument Technology

    Smart air sampling instruments can reduce, minimize and often eliminate the deficiencies of traditional analog air sampling instruments at a time when the industry needs maximum credibility on health and safety issues in preparation for the resurgence of commercial nuclear power plant construction on a worldwide basis. The rapid evolution of microprocessor technology since the mid 1980s has ...

  • Maintaining Quality in Stem Cell Products: Stem Cell Process Monitoring (Series Part 4 of 4)

    Routine cleanroom, clean air devices, and personnel monitoring should be performed during operation throughout all critical stages. Ideally, monitoring should capture all interventions, transient events and system deterioration. The type of contamination being monitoring is either total particle (non-viable) or viable. Requirements for All Types of Monitoring The locations, ...
