Membrane Systems
When making a choice between different kinds of membrane
systems, there are a few factors that are to be considered.
Some of these are costs, risks of plugging of the membranes, packing
density and cleaning opportunities. Membranes are never applied
as one flat plate, because this large surface often results in
high investing costs. That is why systems are built densely to
enable a large membrane surface to be put in the smallest possible
volume.
Membranes are implemented in many types of modules. The two major
types of membranes are the tubular membrane system and the plate
& frame membrane system. Tubular membrane
systems are further divided up in tubular, capillary and hollow
fiber membranes. On the other hand, Plate & frame membranes
are further divided up in spiral membranes and pillow-shaped membranes.
