1.1 Abbreviations and subject index

Softening:
The water purification process removes the hardness from raw
water. Hardness constituents are the portion of calcium and
magnesium ions in the water.
External contacts (input/output):
Is the connection for alarm output & remote ON/OFF.
Raw water:
Raw water (usually untreated drinking water) must often be pre-
treated (usually softening) and is then useable for the desalination
process in the RO device.
RO:
Abbreviation for Reverse Osmosis.
Permeate:
The largely desalinated "pure water" filtered in the RO mem-
branes and generated by reverse osmosis. The characteristic
value is the electric conductivity in μS/cm.
Concentrate:
This waste water, which contains the salts and minerals that have
been removed from the raw water.
Membranes:
The "filter" of the device which is capable of desalinating the raw
water by high pressure and flow.
TDS:
Abbreviation for "Total Dissolved Solids" the total amount of
dissolved salts, measured in mg/l.
SDI:
Abbreviation for "Silt Density Index". The "Silt Density Index"
is an indicator of the organic contamination of raw water. The
measurement system is a filtration process which determines the
blocking tendency, measured during 15 min.

Conductivity, electrical conductivity:
Electric conductivity value of the water of the RO unit, the smaller
this measured value (μS/cm) the better the water quality in the
permeate product.
IOM:
Abbreviation for "Installation and Operating Manual"
Permeate yield (WCF):
The ratio between the produced pure water (permeate) and the
thus required amount of feed water (soft water) is expressed as
permeate yield (WCF) or "Water Conversion Factor".
Pressure tank operation:
The RO units configuration mode could be set for the pressure
tank operation at the range of 2 ... 4 bar.
NO:
Abbreviation for level switch "normaly open" (for level queries
as ascending normally open contact).
Blending of water inlet:
All devices which are equipped with an electrode-controlled tank
level metering, requires a manufacturer's specified conductivity
value for the permissible inlet of feed water. The specified inlet
of softened water has to be adjusted by blending.
