| Abstract:A focused beam reflectance measurement (FBRM) instrument was used to continuously assess the aggregation of stickies in the white water when deinked pulp was used to produce paper. The particle size analysis, turbidity and Zeta potential were also used to evaluate the effisiency of anionic trash catcher in altering the sticikes aggregation behavior. The results indicated that FBRM provided a real-time monitor in process to establish the evolution of the resulting aggregation state as well as differences between different chemical doses. The FBRM results were in good agreement with the particle size analysis, turbidity and Zeta potential measurements. At high pH values, the anionic charge of stickies increased which caused, consumption of chemicals increased. Aggregation should be take place at neutral conditions to increase the aggregation of stickies and to avoid excessive chemical consumption. |
