How does it work?
SYSTEM DESCRIPTION
PURIFICATION TAKES PLACE IN TWO STAGES.
1.
During the pre-filtration stage an active carbon filter removes unwanted odors or tastes
(and within specified limits chlorine and volatile organic compounds) and a 5-micron
preliminary filter that filters out grains and other large particles.
2.
After having passed through the pre-filtration unit, the water is pushed into the
purification unit to an electric pump, which pumps the water under high-pressure (6 bar)
through the membrane filter.
In the membrane filter, two separate water streams are generated.
1.
A purified water stream, which is, led to the conductivity and flow meters, and then leaves
the purification unit.
2.
A reject water stream that leaves the purification unit through the reject water outlet.
The purified 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 purification process:
1.
After pre-filtration 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 filter, the suspended dissolved
pollutants collide with the membrane tissue and stick to it. Effectively removing all harmful
contaminants in the water.
* The reject and our automated back-flush 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 filtration
unit fitted between the feed water source and the purification unit is admitted to the purification
unit. At this entry point also a temperature sensor and a non-return valve are fitted.
