4.2 Process Description
The MEDICA EDI 15/30 process links five purification technologies;
Reverse Osmosis, Electro-Deionization, Ion Exchange, Photo
Oxidation, and Sub-micron Filtration. It also incorporates a
recirculation/delivery pump and an RO feed water boost pump.
The system is designed to operate from a potable water supply, pre-
treated for particle and chlorine removal, and produces up to 15 or 30
liters per hour of reverse osmosis grade water which is further purified
and circulated through a treated water reservoir.
An LCD displays the system status and provides control by means of
three function buttons.
The water is processed and treated by the MEDICA EDI 15/30 system
as follows:
Pre-treated feed water enters through a strainer and inlet
solenoid valve and is pumped by means of an RO boost
pump.
The water then passes the disinfection port and through two
or three reverse osmosis cartridges, set up in series, which
split the flow into permeate and concentrate streams. The
permeate water is further purified with the waste concentrate
stream being passed to drain.
The permeate water then passes though a water quality
sensor which measures the conductivity of the water.
The permeate water passes through the conditioning
chamber of the resin cartridge pack which removes traces of
hardness remaining in the water.
The water then passes through the electro-deionization
module which removes inorganic and organic impurities.
Waste water from the EDI module is passed to drain.
The permeate water is collected within the reservoir.
Water from the reservoir is drawn into the main re-circulation
stream by the re-circulation pump and passes through the
re-circulation purification loop.
This water is pumped directly through the UV chamber
where it is exposed to intense UV radiation to provide
continuous bacterial control by photo oxidation and to
promote the cleavage of organic molecules.
The water then passes through the deionization chamber of
the resin cartridge pack which removes the final dissolved
ionic impurities from the water.
Finally the water is passed through a:
Water quality sensor which measures the resistivity of the
water.
Temperature sensor which provides accurate
temperature measurement.
The purified water passes through a 0.2m filter to remove
any remaining bacteria.
The purified water is either delivered to the analyzer or
returns to the reservoir. The delivery of water is controlled by
means of a pressure switch which senses when the analyzer
demands water.
When diverted to the reservoir, purified water can be
delivered through a dispense tap.

ELGA MEDICA EDI 15/30 Operator Manual
MEDICA EDI 15/30 Version 1 05/16 Page 7
During periods of non-use the system will automatically
operate in intermittent re-circulation mode to maintain water
purity with maximum efficiency.
If the level of water in the reservoir is below 10% (or below
40% on start up) the re-circulation mode will be disabled
until a level of 40% is reached. The re-circulation will restart
automatically.
When the make-up starts, there is an initial 15 minute flush
period prior to water being passed to the recirculation circuit.
After power off or dual cartridge pack exchange this time
period is increased to 30 minutes.

RESTRICTED ENVIRONMENT THIS
COULD BECOME A HAZARD.
Feed Water
The feed water should comply with specifications provided. This
should enter the system via an 8mm (5/16”) O/D semi rigid
tube, and should be in the temperature range 1 to 35°C.
CAUTION! Feedwater temperatures outside the range
1 to 35°C will cause damage to the
MEDICA EDI 15/30 system.
For pressurized feeds, the maximum inlet pressure is 2 bar
(30 psi). Higher feedwater pressures must be reduced using a
pressure reducing valve (Part No. LA 512).
Reservoir feeds to the MEDICA EDI 15/30 system should be
positioned at the same height, or above the system, to provide
a positive flooded inlet pressure.
