  • Inline static mixer simplifies process & reduces cost for yogurt manufacturer

    The increasing popularity of yogurt in recent years-requiring greater production capacity and efficiency-has brought about a need to “re-think” just how best to feed raw materials into mixing and blending systems, and into filling machines. Initially, in most European and U.S. plants, the mixing of milk, yogurt culture, and additives was essentially a hand-batching process. This ...

  • Identifying Low-Frequency Tonal Noise in Windy and Noisy Conditions - Case Study

    Problem A large LNG gas facility (approximately 300m x 150m) producing 300 000 tons of LNG annually is situated in a terminal area with the nearest populated area at a distance of around 1 km. Within the gas production facility, a low-frequency tonal noise at around 500 Hz is generated causing complaints from nearby neighbours. The tone imposes a more stringent noise requirement on the ...

  • Japanese Organics Recycling Association Formed

    Another backyard composting adage states that compost should have the feel of a wrung-out sponge — damp but not dripping wet. Actually, a wrung-out sponge may be on the dry side for composting, but the analogy does provide a great image for understanding the reasons for balancing moisture. Like a compost pile (or windrow or material in a vessel), a sponge is a solid mass containing an enormous ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...

  • A Look at the Impact of Proposed Water Standard to Prevent Legionnaires` Disease

    From the standpoint of water treatment industry experts, failure to prevent legionellosis (or Legionnaires’ Disease) is the most significant water treatment problem today. Essentially every case of the disease is the result of exposure to inadequately managed building watersystems, and both utility and potable water systems can be the source of the hazard (i.e., Legionella bacteria). In ...
