Abstract: The treatment of chlorinated organic compounds during the chlorination (C-stage) C and during extraction state (E) effluents and combined bleaching effluents generated by laboratory bleaching of Indian mixed wood pulp with some flocculants/adsorbent to reduce the COD and couuor was analyzed. Unbleached washed kraft pulp was taken from a paper mill, the kappa number was determined using the Tappi test method T236 CM-85. The pulp was filtered and washed with water, following bleaching in the C and E stages. The filtrate and washing water were collected to generate C stage and E-stage effluent, the combined effluents was generated by simple mixing C and E stage effluents. Color was measured on a Shimadzu spectrophotometer model UV 2100/s, at the wavelength of 465 nm. Some platinum wire was dissolved in hot aquaregia, nitric acid was removed by repeated evaporation with a fresh portion of concentrated hydrochloric acid. Result shows a significant reduction in COD and couuor.
