Abstract
The cost of an alternative method of reducing the dust concentration to which cotton mill workers are exposed was examined. This method involved the purification of humidifier water to prevent the release of dissolved solids in the water into the atmosphere of the facility. Studies have estimated that when atomizers are used for humidification, dust removal by demineralization of the water supplied to the atomizers can be achieved at a fraction of the cost compared with the cost of removing an equivalent amount of dust by conventional air filtration technology. The cost reduction ranged from 1/30 to 1/9th of the cost of systems designed to remove dust once it enters the air. The cost effectiveness of these controls will be greater in colder weather when it is necessary to add more water to the atmosphere of the workplace to achieve comfortable humidity levels. When humidification is supplied to workplace air by air washer systems, the benefits of supply water demineralization are not as dramatic.
