Greenville, RI – Environmental Resource Associates Inc. (ERA) recently completed a design of air pollution control devices for a large grass-roots uranium ore processing facility in southwestern United States. Operations at the facility are to include ore stockpiling and transportation, conveying, SAG milling, screening, chemical leaching, purification and packaging.
ERA’s design was governed by the need to protect workers and the environment from potential radiation and dust hazards typically associated with uranium ore processing. Local and area ventilation systems such as exhaust hoods, canopies, vents and exhausts were sized to adequately capture the pollutants and direct the air streams to the pollution control devices. Various agency standards were applicable including the Nuclear Regulatory Agency, Bureau of Mines, EPA and OSHA.
Due to the variable nature of the pollutants, extreme fluctuations in air temperature and humidity, ERA had to custom design air pollution control devices for each processing area and building. Air pollution control devices included bag houses, dust collectors, wet scrubbers, acid scrubbers, venturi scrubbers and HEPA filter devices.
