Ultrafiltration or UF
is
a pressure driven membrane separation process
that separates particulate matter from soluble
components in the carrier fluid (such as water). UF membranes typically have pore sizes in the
range of 0.01 - 0.10 µm and have a high removal
efficiency for bacteria and most viruses,
colloids and silt (SDI), the smaller the nominal
pore size, the higher the removal efficiency.
Most materials that are used in UF are polymeric
and are naturally hydrophobic. Common polymeric
materials used in UF include: Polysulfone (PS),
Polyethersulfone (PES), Polypropylene (PP), or
Polyvinylidenefluoride (PVDF). Although these
materials can be blended with hydrophilic agents,
the hydrophilic additives can reduce the membranes
ability to be cleaned with strong levels of
disinfectants such as peroxide or hypochlorite to
sufficiently remove bacterial growth.
The modular design ensures that
the capacity to suit a client's requirement and
it can be easily installed. The unit has very
low energy consumption and does not require
continuous inspection.
