AD HR Series
High Rejection Seawater RO Elements
The AD HR Series, family of proprietary thin film
reverse osmosis membrane elements, is characterized by an excellent sodium chloride rejection.
AD HR series is selected when high quality permeate 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 exceeding 800psi (5,516kPa) and elevated seawater temperatures.

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 potentially foul the RO element. For performance consistency and project warranty, please use Winflows projection software and consult your Filters
with Membranes representative.
