Moduł A2 (sediment-carbon-softening):
• Granulated activated carbon - prepares water for the reverse osmosis process. It
lters out all organical and chlorine-based contamination. Contaminants are sorped
on the activated carbon.
• Softening bed removes calcium and magnesium ions, that are responsible for
water hardness.
• 1 μm sediment lter - the last element of pre-ltration, protecting the water for
re-contamination. It lters out all of the mechanical contamination >1 μm.
2.3 Reverse osmosis module – RO
RO membrane holds up to 96-99% dissolved contamination (organic and non-orga-
nic), heavy metals, and radioactive elements of a 0.01 micron size.The osmotic water
conductivity varies between 8-20 μS/cm. Semi-permeable osmotic membrane con-
sists of many perforated layers wrapped around a core located inside the membrane.
Contaminated water is pushed underpressure on thesurface, where waterparticles by
diusion permeate through the membrane. The contamination is rejected and direc-
ted to the outow. Puried water passes through pores to the core, and under pressure
is directed outside the membrane.
2.4 Ion exchange bed demineralization
TOC ion exchange module - contains ion exchange beds in H+/OHˉ ion forms.
Osmotic water is puried by deionization columns, where all remaining mineral
salts are captured. In the ion exchange process ions and particles in water that
have a particular current are bound by ion exchangers (ionites). After this process
conductivity drops to 0,055 μS/cm.
2.0 GENERAL INFORMATION
The fully automated and unattended device has a microprocessor control and measurement system, that
constantly monitors all the stages of water purication process. Obtained water ts the requirements of the
PN-EN ISO 3696:1999, FP, ASTM standard for rst water purity class.
It has extensive automation enabling work monitoring, data archiving, individual setting of alarm thresholds
for parameters of feed water, reverse water osmosis and ultra-pure and control of the recirculation function
and the automatic ushing of membrane modules.The systems are equipped with a number of safeguards
allowing for comfortable operation of the device.
2.1 How it works
The demineralizer operates under tap water pressure. Water purication processes are fully automated
and unattended. The purication process consists of the following stages:
* depends on the model
2.2 Mechanical-sediment-softening ltration
5 μm pre-lter - sediment lter is used for preparing water for further treatment with
the reverse osmosis. It consists of a polypropylene cartridge located in a transparent lter
housing. It holds all types of mechanical contamination of a diameter larger than 5 μm.
