Fact Sheet
AD HR Series
High Rejection Seawater RO Elements
The AD HR Series, family of proprietary thin film
reverse osmosis membrane elements, is character-
ized by an excellent sodium chloride rejection.
AD HR series is selected when high quality perme-
ate is demanded from seawater that is relatively
high in TDS.
AD HR series new membrane chemistry provides
excellent rejection characteristics when operated at
seawater operating conditions (pressures exceed-
ing 800psi (5,516kPa) and elevated seawater tem-
peratures.

SDI is measured on a non-linear scale using a 0.45 micron filter paper.
Additionally, finer colloids, particulates and microorganisms that pass
through the filter paper and not measured in the SDI test, will potential-
ly foul the RO element. For performance consistency and project war-
ranty, please use Winflows projection software and consult your Filters
with Membranes representative.
