Optional Z-Ion and Z-Brane Membrane Protection Systems
The Z-Ion and Z-Brane, both developed by Spectra, are systems to protect the reverse osmosis
membrane from fouling for extended periods without fresh water flushing or storage chemi-
cals (pickling).
The Z-Ion achieves this end by introducing a stream of metallic ions into the fresh water flush
module, thus flooding the entire system with ions that prevent biological growth for up to thir-
ty days. If you are going to let your system sit idle for longer than thirty days, treatment with
SC-1 storage chemical or propylene glycol is still required.
The Z-Brane applies zeta potential high voltage capacitive current to the membrane pressure
vessel, creating an unfriendly environment for bio-film and bacteria, and assists in the preven-
tion of scale formation on the membrane surfaces. After thoroughly fresh water flushing the
system, the Z-Brane will protect an idle system indefinitely as long as the Z-Brane is energized.
The Z-Brane draws less than 1 Amp, but storage with chemicals may be preferable for longer
periods if battery power is an issue.
Neither the Z-Ion nor the Z-Brane will prevent freezing, so in freezing climates pickling with
propylene glycol is still required. Even with the Z-Ion or Z-Brane there may still be cases where
you need to pickle your system with SC-1 storage chemical or propylene glycol, so we recom-
mend you carry one of these products at all times.
If your system was ordered with either of these systems, they will require only some basic wir-
ing and commissioning, laid out in the following pages.
If you didn't order you system with the Z-Ion or Z-Brane, either can be retrofitted to any Spec-
tra system.
