A demonstration plant was installed and operated to determine effectiveness and feasibility of using massive lime treatment (that is, 20,000 ppm lime) to decolor kraft pulp mill effluents. The two most highly colored effluents and mixtures of these treated in the demonstration plant were: (1) the almost black effluent from the caustic extraction stage of pulp bleaching, and (2) the light reddish-brown effluent from the final unbleached pulp washing stage. Objectives were to determine: Effectiveness of color removal, design and performance of massive lime system equipment, effects on normal pulp mill operations, effects on pulp quality, operating costs. Impact of the massive lime system on a hypothetical 1000 tons-per-day bleached kraft pulp and paper mill is described.
