Chemical and biological methods for color removal from wastewater of carton-printing ink industry / Selasiah Wahab

Water-based and solvent-based ink wastewaters from carton-printing industry are generated from the cleaning of printing machines when the color of the printing ink is changed. Generally, the wastewater is intense in color and high in composition of organic compounds. Colors are recalcitrant compound...
