Experiments were performed on synthetic smelt made of 80 34 wt% Na2CO3 and 20 wt% NaCl at 800°C, 900°C, and 1000°C. The results show that upon contact with water, some smelt droplets explode immediately and break into small pieces, some require a delay time to explode, and others solidify without exploding. The probability of explosion strongly depends on water temperature and, to some extent, smelt temperature. WASTEWATER TREATMENT Upgrading aeration system performance in secondary basins treating pulp and paper wastewater J. Palumbo, P. Cyr, R. Sackellares, and P. Wiegand This paper provides an introductory resource for understanding and addressing the complexities often associated with achieving an optimal aeration system upgrade. Relevant aeration and mixing science fundamentals and commonly employed aeration technologies are summarized and reviewed. The application of wastewater treatment computer models is examined as it pertains to aeration system design and operation. Recommendations for aeration system upgrade projects include specific information needs, potential resource requirements, general model selection guidance, and discussion of potential model application methodologies. Paper360º SEPTEMBER / OCTOBER 2015 Understanding coating strength at the molecular and microscopic level Martti Toivakka, Parvez Alam, Farid Touaiti, Anniina Oravilahti, Tuomas Oravilahti, Juha Knuutinen, Robert Nilsson, Mahdi Pahlevan, Mia Ahokas, and Carl-Eric Wilen Experiments and numerical simulations were used in this study to better understand the microscopic and molecular level interactions between the latex-binder and dispersant-covered coating pigments used in paper coating. Micromechanical simulations were carried out to identify the microstructural variables most influential to strength. Several new pigment dispersing agents were synthesized with the reversible addition-fragmentation chain transfer copolymerization technique, and their dispersing effect and influence on dry and wet strength of pigment coating were evaluated. Molecular level interactions between binders, coating pigments and various functional groups used in the dispersants were studied with molecular modeling. Furthermore, dynamic mechanical thermal analysis was used to examine the influence of both commercial and novel dispersants on the pigment-latex interactions. PULPING A novel approach to white liquor control in a continuous digester using the Box-Jenkins methodology to predict chip bulk density Flávio Marcelo Correia, José Vicente Hallak d'Angelo, and Sueli Aparecida Mingoti This research proposes a new approach using the Box-Jenkins methodology to develop a dynamic model for predicting chip bulk density. Industrial data were gathered on 1,948 observations over a period of 12 months from a Kamyr continuous digester http://WWW.TAPPI.ORG http://WWW.TAPPI.ORG
