1. Operation continuously with temperature at 85℃.
2. All spiral membrane elements can be made into
high temperature membrane.
3. Due to temperature rises, pressure decreases,
flux increases, rejection decreases.
Due to temperature rises, pressure, rejection, flux and drop pressure will be changed. The relationship between temperature, pressure, rejection, flux and drop pressure as below:
1）The relationship between temperature and pressure
Relationship between membrane element operating pressure
and temperature as shown in the right form: it can help
customers to determine the maximum application conditions
of high temperature membrane element.
2）The relationship between temperature and rejection
Due to temperature rises, membrane rejection decreases.
For example Nacl, as shown in the right form.
3）The relationship between temperature and flux
Due to temperature rises, membrane flux increases.
Temperature rises 1℃, flux increase 3%.
