Reverse Osmosis Module Ro; Ion Exchange Bed Demineralization - HYDROLAB HLP Serie Instrucciones De Uso

Module A2 (sediment-carbon-softening):
- Granulated activated carbon - prepares water for the reverse osmosis process. It
filters 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 filter - the last element of pre-filtration, protecting the water for
re-contamination. It filters out all of the mechanical contamination > 1 μm.
2.3 Reverse osmosis module – RO
The RO membrane holds up to 96-99 % organic and non-organic contamina-
tion dissolved in water, heavy metals. Semi-permeable osmotic membrane con-
tains many layers wrapped around a perforated core located inside the module.
Contaminated water is pumped under pressure on the membrane surface, where
the water particles go through the membrane by diffusion. The contaminants are
separated and go into the waste. Purified water flows through the central core and
under pressure flows out of the module. This process is critical to the efficiency of
the whole system.

2.4 Ion exchange bed demineralization

Ion exchange module - contains mixed beds of ion exchange resins in ion forms
+
H /OHˉ. Osmotic water is purified on the deionization columns, where the rema-
ining salts are being captured. In the process of ion exchange dissolved ions and
particles have an electric charge that is bound by ionites. After this process, water
conductivity drops to 0,055 μS/cm.
Ion exchange modules of the TOC are dedicated to researches
requiring low amounts of organic carbon.
