Characterization of wastewater from LEP technology prints recycling process

Traditional chemical deinking process is widely used in paper recycling industry and it is considered to be effective for the removal of ink particles. Considering that the process uses large quantities of water and chemicals the effluents can contain inorganic and organic pollution. In this study effluent characteristics from laboratory deinking process of LEP technology prints were examined. The prints were obtained by varying the voltage of the developing drum in indirect electrophotography printing with liquid toner on two different paper substrates. The effluents obtained after all chemical flotation deinking processes were analysed in terms of pH, electrical conductivity, total organic compound and chemical oxygen demand.
