- When PH is above 10, the Maximum Temperature of Continuous
Operation is 35ºC.
- Under certain conditions, the presence of free chlorine and other
oxidants in the water may cause serious membrane damage, which
doesn't belong to product warranty range.
The principle of nanofiltration is the same as that of membrane
separation processes such as ultrafiltration and reverse osmosis.
Nanofiltration is also a membrane separation process driven by
pressure difference, which is an irreversible process. The separation mechanism can be described by the charge model
(space charge model and fixed charge model), pore model, and
electrostatic repulsion and steric hindrance models that have only
been proposed in recent years. Compared with other membrane separation processes, an advantage of
nanofiltration is that it can retain small molecular weight
organics that pass through the ultrafiltration membrane, and can
dialyze some of the inorganic salts retained by the reverse osmosis
membrane—that is, it can synchronize "concentration" and
desalination. conduct.
