2.2 Process description
The NoNa
+
has three modes of operation that make use of the drain water circuit
and/or the wastewater circuit. Sodium is removed from the water in the drain water
circuit. The sodium is transferred to the water in the wastewater circuit.
The three modes of operation are:
Purification (sodium removal)
This is the mode in which sodium is removed from the drain water. The sodium
is transferred to the wastewater. At the same time, the wastewater ensures
that the stack is cleaned continuously (using acid). See "Purification (sodium
removal)" on the facing page.
Intermittent (acid) cleaning
Once a preset volume of water has passed through the stack, the NoNa
+
starts
the intermittent (acid) cleaning process. This is done to clean the stack. See
"Intermittent (acid) cleaning" on page 14.
Idle
Once every 48 hours, the NoNa
+
performs a short flush with fresh water to
keep the membranes moist.
If the NoNa
+
(or the stack itself) has not been connected for more than 48
hours, add a saline solution to the stack to keep the membranes moist and to
prevent bacteria from entering the stack. See "Keeping stack moist" on page 63
for more information.
