Abstract

The objective of this study was the evaluation of optical, and mechanical properties of chemi-mechanical pulp which was bleached using one and two stage bleaching sequence with hydrogen peroxide and sodium hypochlorite. Also the environmental effects of effluents from bleaching liquor were studied. For this purpose, unbleached CMP pulp produced using mixture of hardwoods was obtained from Mazandaran Wood and Paper mill. Then, the pulps were bleached using P (hydrogen peroxide), H (sodium hypochlorite), PH (Hydrogen Peroxide and sodium hypochlorite) and HP (sodium hypochlorite and hydrogen peroxide) sequences. 60 gr/m2 hand sheets were prepared and the optical, mechanical properties of hand sheets and also the effluent characteristics from bleaching were measured and analyzed based on TAPPI and APHA Standard method. The results showed that when peroxide was applied at the last stage of bleaching, the properties such as tear, tensile and brightness were increased and yellowness was decreased. Generally, the role of single sequence of bleaching using P and two stages bleaching with HP were more effective than single stage H on unBleached pulp. Based on the results, the highest and lowest COD load was related to bleaching effuent of H and PH respectively. Moreover, bleaching liquor of hydrogen peroxide had the highest BOD load and the lowest amount of BOD was related to PH sequence.
