Abstract

In this work, we address the mechanical response of the flat sheet polymeric water treatment membranes under the assumed operational loading conditions. Firstly, we perform quasi-static analyses of the membranes under normal pressure loads, which is the condition that resembles the actual loading for flat sheet membranes in the submerged membrane bioreactors. Then, the long-term deformation of the membranes is studied under the assumed filtration durations for the same loading conditions by utilizing the viscoelastic material models. The quasi-static and viscoelastic membrane simulations are performed by a commercial finite element code ANSYS. Finally, the mechanical fatigue life predictions are carried out based on the stress distributions from the quasi-static analyses and the long-term effects from the viscoelastic analyses.
平板水处理膜的力学分析
在这项工作中,我们解决了平板聚合物水处理膜在假定的操作负载条件下的机械响应。首先,我们在正常压力载荷下对膜进行了准静态分析,这与浸没式膜生物反应器中平板膜的实际载荷相似。然后,利用粘弹性材料模型研究了相同加载条件下假设过滤时间下膜的长期变形。利用商用有限元软件ANSYS进行了准静态和粘弹性膜的模拟。最后,基于准静态分析的应力分布和粘弹性分析的长期影响,进行了机械疲劳寿命预测。
