AD LE Series
High Rejection High Flow Seawater RO Elements
The AD LE Series, family of proprietary thin film reverse osmosis membrane elements, is characterized by an excellent sodium chloride rejection. AD
LE series is selected when high quality permeate is
demanded from seawater that is relatively high in
TDS.
AD LE Series new membrane chemistry provides
excellent rejection characteristics when operated at
seawater operating conditions (pressures exceeding 800psi (5,516kPa) and elevated seawater temperatures.
Table 1: Element Specification

Average salt rejection after 24 hours operation. Individual flow rate
may vary +25%/-15%.

Testing conditions: 32,000mg/l NaCl & 5mg/l Boron solution at 800psi
(5,516kPa) operating pressure, 77°F (25°C), pH 8.0 and 7% recovery.

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.
