  • Characterizing potential water quality impacts from soils treated with dust suppressants

    Received for publication April 24, 2008. Two separate laboratory experiment series, surface runoff and steady-state seepage, were performed to determine if dust suppressant products can be applied to soils with an expected minimal to no negative impact on water quality. The experiments were designed to mimic arid field conditions and used two soils (clayey and sandy) and six different dust ...

  • Pleatable UPE membrane media in pulse-cleaned dust removal air applications
