4.3.2 Operating the HydroPower RO
What is Pure Water?
Pure Water is water in its purest form, physically processed to remove the minerals that
would otherwise lead to limescale spots and streaks. Such impurities are referred to as TDS
(Total Dissolved Solids) and are measured in ppm (parts per million). Water is considered
100 % demineralised (pure) when its TDS is measured at 0 ppm. TDS of 180 ppm is
considered as average water hardness.
Flow of water purification
The water enters the HydroPower RO via the water inlet (1).
The carbon/sediment combi pre-filter (2), which filters out the largest impurities and chlorine from the water
and thus protects the membranes, sits before the membrane.
The membrane filter (3) removes up to 98% of the minerals from the water in the HydroPower RO.
The resin filter (4) sits after the membrane, which removes the last 2% of the minerals from the water in the
HydroPower RO.
Pure water is discharged from the water outlet (5) into a hose connected to a water fed pole for cleaning glass
surfaces without chemicals.
The three (3) filter cartridges (2-4) can be easily removed and replaced (see section 7.3.1).
