Our Cycle Hit System of Iwakuni Mill started up from Febrary 1993 and Coated paper product waste liquor (Color waste liquor) has been treated succesfully with it.<BR>In this system, primary plus secondary sludges are directed to a slugde conditioning tank, where it is dosed with an inorganic coagulant and mixed to neutralize the surface charge of the sludge particles.<BR>This conditioned sludge is then sent to a pelletizing/thickening tank, where an anionic and an amphoteric polymers are added to pelletize the sludge. Using the same tank, water can be removed with a special built-in device, resuluting in a sludge with an increased concentration of solids.<BR>This report described the summary of operation.
