Note on Water Quality
For the purposes of SPTFF, the term purified water refers to de-ionized, 0.2 µm filtered water.
Using unfiltered water can foul the membrane in the Cadence ILC module.

u
Procedure A — Connect the Cadence ILC Module to the Tubing
CAUTION!
All equipment (pump, pressure can, etc.) and plumbing upstream of the Cadence
ILC module must be sanitized and flushed prior to connecting to the module.
Prepare to use the Cadence ILC module following these steps:
1. Wearing protective gloves and safety glasses, open the Cadence ILC module bag and
remove module from bag.
2. Remove the caps from the ports.
3. Connect tubing to appropriate module ports.
HELPFUL INFORMATION!
Cadence ILC modules are operated without a holder. The module
must always rest on its bottom feet and never on its side to avoid damage to the ports.
CAUTION!
Do not exceed a feed pressure of 4.1 barg (60 psig) at 20 – 40 °C during any
pre-use, processing, or post-use procedures. Exceeding 4.1 barg (60 psig) of feed pressure
can permanently damage the Cadence ILC module or lead to product leakage. Do not exceed
a feed pressure of 1.5 barg (22 psig) when the permeates are fully closed. Additionally, do not
exceed the pressure rating of the tubing during operation or integrity testing. Tubing that is
rated to at least 4.1 bar (60 psi) should be used.
u
Procedure B — Flush the Cadence ILC Module with Purified Water
Cadence ILC modules are stored in a solution containing:
– Delta membranes: 5% ethanol and 1% sodium diacetate
– Omega membranes: 0.3 N sodium hydroxide
