Abstract
Methods of and systems for dispensing dust suppressant are provided. The methods comprise forming an aqueous dispersion stream by delivering a surfactant composition to an aqueous liquid stream. The aqueous dispersion stream is mixed to form a dust suppressant. The dust suppressant is dispensed to a surface at a pressure sufficient to provide coverage of the surface. Surface tension of the dust suppressant is measured via a tensiometer, and the measurement is relayed to a controller. The forming of the aqueous dispersion stream is adjusted according to the measured surface tension relayed to the controller. The systems are configured to carry out one or more of the provided methods.
