Powder Reclamation Methods

Abstract

Dust collection is necessary due to the fact that the deposition efficiency of any spraying process is rarely 100 % and therefore, depending on the application, any fugitive particulate or overspray must be collected to comply with the workplace environmental and safety requirements. The primary way for a powder to be reclaimed is through the use of a dust collector system designed to meet the environmental challenges of the particulate running through it. The most important part of the collector is the filter, which is designed with a filtration media to get the longest filter life possible while providing efficiency to meet environmental expectations. Dust collector’s themselves can also have technologies that enhance product performance and serviceability. To collect particulate properly, best practices guidelines are described for ventilating hoods and booths. Lastly, once powder is reclaimed, considerations for disposal and regulatory compliance must also be addressed.
