This article provides an overview of the membrane bioreactor technology where nonwovens can be applied as an alternative medium for separation. The main objective is to identify the nonwoven characteristics leading to higher removal efficiency, higher flux, and lower fouling behavior. The general limitations associated with common nonwoven separation media are related to the large pore and wide pore size distributions. Consequently, due to their large pore network, nonwovens often behave as a depth filter structure. Common nonwovens having large fibers cannot replace microfiltration membranes yet. Further refinements of these structures are necessary for developing a suitable replacement.

本文概述了膜生物反应器技术，其中非织造布可用作分离的替代介质。主要目的是确定导致更高去除效率，更高通量和更低结垢行为的非织造布特性。与普通非织造分离介质有关的一般限制与大孔和宽孔径分布有关。因此，由于其大的孔网络，非织造布通常表现为深度过滤器结构。具有大纤维的普通非织造材料还不能代替微滤膜。这些结构的进一步改进对于开发合适的替代品是必要的。
