How does it work?
SYSTEM DESCRIPTION
PURIFICATION TAKES PLACE IN TWO STAGES.
1. During the pre-ltration stage an active carbon lter removes unwanted odors or tastes
(and within specied limits chlorine and volatile organic compounds) and a 5-micron
preliminary lter that lters out grains and other large particles.
2. After having passed through the pre-ltration unit, the water is pushed into the
purication unit to an electric pump, which pumps the water under high-pressure (6 bar)
through the membrane lter.
In the membrane lter, two separate water streams are generated.
1. A puried water stream, which is, led to the conductivity and ow meters, and then leaves
the purication unit.
2. A reject water stream that leaves the purication unit through the reject water outlet.
The puried water stream is led to the mineral cartridge and from there to the water faucet; the
rejected water is led into the domestic drain system.
MEMBRANE PURIFICATION AND REGENERATING PRINCIPLE
The following happens during the purication process:
1. After pre-ltration the pressure of the water is increased to 6 bar before being pressed
through the membrane.
2. As the feed water is pushed through the membrane lter, the suspended dissolved
pollutants collide with the membrane tissue and stick to it. Eectively removing all harmful
contaminants in the water.
* The reject and our automated back-ush enables the system to take care
and clean itself. This enables a longer membrane lifetime while ensuring
only the highest quality of pure water to leave the system.
3. During the process the pressure of the water is reduced to 2 bars which is also the
pressure at which the pure water leaves the system.
4. Optionally, before reaching the tap the water can be mineralized using our mineral
cartridge.
CONTROLLING THE PROCESS
When the system is powered up, and a correct feed water pressure (between 2 bar and 6 bar) is
detected, the solenoid valve in the feed water inlet tube is opened, and water from the ltration
unit tted between the feed water source and the purication unit is admitted to the purication
unit. At this entry point also a temperature sensor and a non-return valve are tted.

From the entry point the feed water is pushed under feed water pressure to an electrical pump
that forces the feed water under high pressure through the membrane. Pump pressure is
monitored in the pressure line to the membrane, while pump motor current is also measured as a
process parameter.
Once the puried water is through the membrane its temperature, electro-conductivity and
ow rate are measured to monitor the quality and quantity which determines the membranes
condition.
A pressure regulator provides the correct back-pressure in the reject stream to reach the nominal
pressure on the membrane. During a ush an additional solenoid valve opens a by-pass channel
which makes it possible to use the full pump pressure. All ushes are automatic but can also be
initiated manually.
All sensors and valves are contained in the measuring and control block that also houses a CPU
that translates pressure and temperature into digital information. From the purication unit the
water is led through the mineral cartridge (optionally) and from the mineral cartridge to the water
faucet. See gure 8 for an explanation of the valve block.
