Salt free goatskin preservation with sugarcane bagasse and silica gel: salinity reduction in tannery wastewater

Common salt (NaCl) is conventionally used for the preservation of animal skins. Succeeding soaking operation increases the massive chloride (Cl−) content and total dissolved solids (TDS) in emitted wastewater. Minimizing high Cl− and TDS, an approach of substituting NaCl; silica gel merged with bagasse has been taken underneath the light to preserve raw goatskin. A raw goatskin was ripped into equal two parts, half was applied with 50
