Abstract
Laboratory-scale studies focused on recovering potassium sulphate from stillage using the wet digestion technique. The study optimized processes like acid digestion, clarification, evaporation, crystallization, and decolorization. Findings indicate the dependency of the digestion process on sulfuric acid concentration, with specific optimization durations identified for different stages.
