In the rotary drum crystallizer, solids are deposited from a molten liquid mixture on the cooled surface of a drum. Rotation of the drum carries the solids from the melt to a scraper blade which removes the crystal deposit in a liquid free, convenient form. The object of this investigation was to ob

Abstract
The equation traditionally used to analyze a rotaryβdrum vacuum filtration system is strictly valid only for flat filters immersed during the filtration cycle. In this article we derive the equation appropriate for a rotaryβdrum filter and find that the results of calculated areas differ by a factor 5 from the fully immersed filter result.

Kynch's theory of sedimentation is adopted to solve for the attainable steady state concentration in a vertical continuous sedimentation basin incorporating a thickener and a clarifier. The limiting flux solution corresponding to the local minimum at the flux concentration curve is proved to have a
