The Atmospheric Dust Problem

This article concerns the control of emissions from a local dolomite plant through a series of corrective measures. With a new State regulation on particulate emissions (process weight table) passed in 1965, and with a new local control program, a goal was established toward which control measures were directed. Inplant investigations revealed that measures would be necessary to eliminate emissions from the pulverizer and conveyor belts. In order to meet State requirements, a better method of collection for the dryer was required. In order to evaluate the effect of these changes on the ambient air, dustfall jars and high-volume air samplers were used and stack sampling was conducted at and around the local dolomite plant and also at another such plant in Venice, Fla. Through successive control and testing, emission factors for dolomite plants, as well as reduction of plant emissions and resident complaints, were established.
