Abstract

Using high CONSISTENCY pulp especially in bleaching plant is highly attractive due to considerable reduction in energy and water consumptions and low effluent volume. This research investigates the effect of CONSISTENCY CMP PULP on bleaching by HYDROGEN PEROXIDE. For this purpose, unbleached mixed hardwood CMP PULP of Mazandaran wood and paper CO. mill was used. Bleaching was carried out with QP sequences. Pretreatment or Q stage was carried out by DTPA as a chelating agent for removing transition metals. Chelating stage had a similar condition for all pulps. bleaching with HYDROGEN PEROXIDE was carried out in three levels of HYDROGEN PEROXIDE 2, 3, 4% and proportion NaOH to H2O2: 0.8, 0.7, 0.6 by adding 3% sodium silicate in 70°C and 150 min at four CONSISTENCY level (10, 15, 25 and 30%). After bleaching, handsheets were made with grammage 60gr/m2 from bleached pulp. The experimental results showed that high BRIGHTNESS and OPACITY and lower YELLOWNESS was obtained at 30% CONSISTENCY by 2 and 3% peroxide charge. However, by using 4% HYDROGEN PEROXIDE, higher BRIGHTNESS and lower YELLOWNESS attained at 25% CONSISTENCY. BRIGHTNESS is increased continuously by increasing CONSISTENCY from 10 to 30% at 2, 3% peroxide. But at 4% peroxide charge, BRIGHTNESS is increased from 10, 15 and 25%, and then at 30% CONSISTENCY is decreased significantly. Also under conditioning of 2% peroxide and 30% CONSISTENCY and 2% peroxide at 25% CONSISTENCY can obtain similar BRIGHTNESS to 3% peroxide and 25% CONSISTENCY and 4% peroxide at 10% CONSISTENCY. That it means of 25, 30% decrease in consumption peroxide and sodium hydroxide.
