Pressure filtration is an important method for removing liquids from a suspension. Difficulties arise in modeling this process for cases where the particles are soft and porous. Here the dewatering is governed by processes occurring on two different porosity scales Although this class of problem is commonly found in natural and engineering settings, the motivation of this work stems from a Pulp and Paper application in pulp processing. In particular, this work is a partnership with Valmet (Montreal) in which we will examine 1D pressure filtration at rates comparable to industrial levels and model the dynamics occurring at the microscale. Comparisons of the model predictions will be made to pilot plant data. The project will be over a four year period in which the work will be conducted by 1 PDF, 1 PhD and 2 undergraduate students.

加压过滤是从悬浮液中除去液体的重要方法。在模拟这种情况下，颗粒是软的和多孔的过程中出现的困难。这里的脱水是由两个不同的孔隙率尺度上发生的过程虽然这类问题是常见的自然和工程设置，这项工作的动机源于纸浆和纸张应用在纸浆加工。特别是，这项工作是与Valmet（蒙特利尔）的合作伙伴关系，我们将以与工业水平相当的速度检查1D压力过滤，并对微观尺度下发生的动态进行建模。将模型预测与中试工厂数据进行比较。 该项目将在四年的时间内，工作将由1个PDF，1个博士和2个本科生进行。
