Abstract

Study results of the effect of reducing the steps of the bleaching scheme hardwood sulfate pulp including oxygen-alkaline treatment (OAT) to obtain chlor-organic compounds in filtrates and cellulose. It was determined that a shortened bleaching scheme including oxygen-alkaline treatment would reduce chlorine dioxide consumption by 48 %, to achieve the requirements of best available technologies for the discharge of adsorbed organically bound chlorine in wastewater and the total organic chlorine content in deciduous bleached cellulose.
