Membrane Preparation<br />
The <strong>Helmholtz</strong>-<strong>Zentrum</strong> <strong>Geesthacht</strong><br />
made machine (center of picture)<br />
allows casting of microporous support<br />
membranes onto fleece material on<br />
rolls up to 70 cm width. These<br />
support membranes are produced by<br />
a precipitation process from polymer<br />
solutions into water. They are highly<br />
porous and show an evenly smooth<br />
surface.<br />
Membrane casting machine<br />
This machine coats support<br />
membranes with functional thin film<br />
separation layers. These layers from<br />
silicone or PTFE can be produced in<br />
the range of 0.5 to 10 µm thickness.<br />

The department of Polymer Technology constructs and builds membrane modules with new developed<br />
membrane materials for technical applications. This combination of chemistry (developing new membranes)<br />
and process engineering (building modules and realizing projects) is the key of success of our research center.<br />
Flat sheet membrane modules are designed in the envelope type<br />
that enables membranes exchange easily. These modules are<br />
applicable in nanofiltration, vapour permeation and gas<br />
permeation processes. Slightly modified modules are suited for<br />
high operation pressure up 120 bars.<br />
Minimodul K100<br />
The modules for nanofiltration are constructed in the envelope<br />
type also, that allow changing of membranes easily. This type<br />
can be used for separation/recovery of organic solvents. These<br />
modules allow high operation pressure and the liquid feed is<br />
directed by flow pattern.<br />

Nanofiltration plant<br />
Newly developed membranes are<br />
tested for the permeability of different<br />
organic vapors in the depicted vapor<br />
permeation test apparatus. The<br />
installation inside a commercially<br />
available drying oven allows simple<br />
thermostating to constant<br />
temperature.<br />
Dampfpermeationstestzelle<br />
The permeability of a varity of gases<br />
is measured in gas permeation test<br />
plants. These are available for<br />
different membrane areas, reaching<br />
from small test cells (in the range<br />
from 10 to 1000 cm²) up to modules<br />
(some m²).<br />
