The hollow fiber ultra-filtration membrane is encased in a reinforced epoxy glass shell as an
integrated unit. This design takes into account the
stress on the module when the casing is joined to the
membrane. The water inlet and outlet are located at
the end of the module. The module is small and
compact, easy to install and the system can be fully
automated. The maximum water inlet pressure can
reach up to 0.6MPa and allows a pressure difference
up to 0.2MPa. The 8080 module system filtration
area (based on the membrane surface area) is twice
that of the 8040 module system. To ensure the
effective transmembrane pressure, the permeate must
be allowed to flow from both permeate outlet points.
When operating, the pressure should be slowly rises or depressed in order to avoid changing
suddenly
Ultra-filtration is a pressure-driven purification process in which water and low molecular weight
substances permeate a membrane while particles, colloids, and macromolecules are filtered. The
primary removal mechanism is size exclusion. A properly designed UF cartridge allows efficient
rising of ionic residue from the cleaning and rapidly returns to optimal resistivity and organic
purity. Reagent-grade sodium hydroxide has proven to be an effective cleaning agent with the
following benefits
