ABSTRACT George Chase CTS-9410275 It is proposed to investigate the filtration processes of water drainage and fine particle retention, with special relevance to the operation of the wet-end of paper machines. Cake filtration and particle retention in deep beds will be simulated, and the material coefficients will be obtained from experiments. The deformation behavior of wet pulp mates as a function of the applied pressure, flow rate and pulp properties will be determined in laboratory. The fine particle retention will be measured by sectioning, electron microscopy, and gravimetric method. This project will be performed by collaboration between G. G. Chase of Akron University, Akron, OH, and B. V. Ramarao of SUNY, Empire State Paper Research Institute, Syracuse, NY. Cost sharing is provided by both institutions. If successful, the resulted predictive model for cake information will be used to evaluate filtration processes under dynamic conditions, with particular application in the paper making machine and other manufacturing processes. ***

摘要乔治大通CTS-9410275 建议研究排水和细颗粒留着的过滤过程，特别是与造纸机湿部操作有关的过滤过程。 对滤饼过滤和颗粒在深床中的滞留进行了模拟，并通过实验获得了物料系数。 将在实验室中确定湿浆伴侣的变形行为作为施加压力、流速和纸浆性质的函数。 将通过切片、电子显微镜和重量法测量细颗粒保留。 该项目将由G. G.阿克伦大学的蔡斯，阿克伦，OH和B。纽约州立大学的V. Ramarao，纽约州锡拉丘兹帝国造纸研究所。 费用由两个机构分摊。 如果成功的话，所得到的滤饼信息的预测模型将用于评估动态条件下的过滤过程，特别是在造纸机和其他制造过程中的应用。 ***
