Suspended solids and colloidal materials
cause membrane fouling in RO system. In order to take some measure
of the degree of this fouling problem, SDI test is
required.
RO element specifications usually call
for the SDI value to be below 5.
Water sources in a RO system often
change their water quality and this often needs to be done weekly
or monthly.
