Abstract : This technical report is divided into two volumes. Volume I explains the study and results of the treatment of Bicarbonate of Soda Stripping (BOSS) waste sludge generated in paint-stripping operations, while volume II contains the supporting data of the study. The study of Bicarbonate of Soda Stripping determined chemical and physical differences between the fresh and spent sodium bicarbonate paint-stripping media. The study evaluated core technologies for treatment of Bicarbonate of Soda Stripping (BOSS) waste sludge generated in paint-stripping operations using bicarbonate paint-stripping media. Detailed physical and chemical analysis were completed of new and spent media. The particles showed evidence that the media was physically altered during the stripping process. Paint stripping is treatable with commercially-available equipment typically used for solid-liquid separations. Vertical leaf pressure filtration was determined a superior technology when judged by the selection criteria used. This study encourages the use of a precoat filter aid (e.g., diatomaceous earth) with the vertical leaf pressure filter system for treatment of spent sodium bicarbonate paint-stripping media. jg p3
