Product Description
2.1
PRODUCT DESIGN
MICRODYN capillary modules contain a bundle of symmetric, hydrophobic polypropylene capillary membranes with a nominal
pore size of 0.2 micron. The capillary membranes are potted in polyurethane. MICRODYN capillary modules were developed for
cross-flow microfiltration (CMF), a modern filtration procedure for separating suspended solids and for low concentrations of
emulsions.
2.2
CROSS-FLOW MICROFILTRATION
The feed flows inside the membrane lumen (or inside the membrane fibers) are as shown in Figure 1. A part of this feed exits the
capillary membrane as filtrate, or clean water, due to a pressure difference across the membrane. The remaining liquid is called the
retentate/concentrate.
