Schematic diagram of purification process (discharging stack)
The purification process works as follows in the drain water circuit:
Drain water is supplied from the drain water tank.
The drain water pump sends the water into the NoNa
+
.
The drain water flows past:
multiple pressure gauges (this is where the pressure is measured)
a flow sensor (this is where the flow rate is measured)
one or two ring filters (this is where the water is filtered)
a sampling valve (this is where you can take samples)
an EC sensor (this is where the EC level is measured)
The drain water enters the stack via one valve.
The stack is equipped with:
current/voltage meter (this is where the electrical current and voltage are
measured)
ion-selective membranes
electrodes
In the stack, sodium (and other monovalent ions) is removed from the drain
water.
The purified water leaves the stack via one valve.
The purified water flows past an EC sensor and a sampling valve.
The purified water flows into the drain water tank.
At the same time, the wastewater circuit is active. The sodium removed from the
drain water enters this circuit.
The wastewater pump draws water from the wastewater tank.
The wastewater flows past:
multiple pressure gauges (this is where the pressure is measured)
a flow sensor (this is where the flow rate is measured)
a ring filter (this is where the water is filtered)
The wastewater enters the stack via one valve.
The stack is equipped with:
NoNa
