  • Air Sampling During NPP Accident

    There has been considerable interest recently generated regarding emergency air sampling protocols as a result of the Fukushima accident in Japan. A major concern involving air sampling requirements is the accurate determination of gaseous-radioactive iodine species emitted from the NPP to the environment as a result of an accident. During normal NPP operation gaseous radioactive iodine ...

  • Air/water cleaning for the control of particulate fouling

    Fouling of feed spacers in spiral wound membrane elements due to particulate fouling and biofouling is one of the main operational problems of nanofiltration or reverse osmosis membrane plants. Removal of particulate fouling from spiral wound membrane elements is investigated using frequent air/water cleaning (AWC). In a pilot setup two spiral wound elements were operated in parallel and were fed ...
