1.7 Specifi cations of the feed water
Water to be treated must be clear and drinking type; it must comply
with the parameters recommended by the 98/83/EC standard. The max.
allowed concentration is the following:
Appearance
Turbidity
Iron
SDI (Silt Density Index)
Water temperature
Free chlorine
TDS (Total Dissolved Solids)
Water hardness
SO4
SiO2
TOC (Total Organic Carbon)
COD (Chemical Oxygen Demand)
Again depending on the characteristics of the water being treated, the
membrane separates around 93 % of all dissolved salts and can also trap
bacteria. Nonetheless, it is also worth checking the quality of the feed
water, so the membrane will not be damaged over time by the action of
microorganisms.
