• Description:
  Charged sprays and fog were evaluated for reducing respirable dust concentrations. Charged spray technology was reviewed for effectiveness, equipment, and theoretical considerations. A mathematical model was developed for predicting dust reduction efects. Laboratory tests were made showing charged spray is considerably more effective at reducing dust on a unit water basis than hydraulic spray. Positive and negative sprays are equally effective. Combined polarity sprays are considerably less effective than either polarity alone. Charged sprays are an available dust control technique best suited to applications where water usage must be limited and long contact time between spray and dust is possible.
