A LABORATORY INVESTIGATION FOR ASSESSING THE EFFECTIVENESS OF WASTEWATER TREATMENT USING FLOCCULATION PROCESS IN BUILDING STONE PROCESSING INDUSTRY ON STONE SURFACE QUALITY AND ABRASIVE TOOL WEAR

Abstract In this study, the effect of presence and concentration of two synthetic polymeric flocculants with different charging mechanisms (anionic and cationic) on surface quality and abrasive tool wear in polishing process of building stones was investigated.The polishing tests were performed Bodysuit in laboratory scale on two stone samples (gra
