For many years, GE has partnered with our
customers requiring ultrapure water and
treatment of other difficult to treat streams and
provided solutions based on the patented High
Efficiency Reverse Osmosis (HERO
HERO operates at a very high water conversion
factor (typically an overall recovery of 90% to
98%) while producing a much higher quality
effluent water when compared to traditional
water treatment technologies. The HERO process
can operate reliably at a flux rate of 30 GFD or
more, handle higher levels of silica in the feed,
reject silica and boron more efficiently, and elimi­nate biofouling – parameters that are difficult to
achieve using a traditional RO.

Now, GE has taken the benefits of the HERO proc­ess and added more value with our pre­engineered design packages. Depending on the
application, one, some, or all of these design mod­ules (See Figure 2) can be utilized to treat a variety
of feed sources.

Figure 2: UPW Design Modules

MOD-1 – Pretreatment

.

Unit operations selected based on
feed water characteristics such as
hardness and alkalinity. In general,
this module can consist of blend water
tank and pumps, prefiltration, heat
exchanger, softener, and weak or

strong acid cation columns.

MOD-3 – Primary UPW

A storage tank with a nitrogen blanket
is provided for RO permeate collection.
From the storage tank, product is
transferred through TOC UV units to
either electrodeionization (EDI) stacks
or primary mixed beds. Finally, gas­transfer membranes are used to
remove CO2 and further enhance

roduct water quality.

MOD-2 – HERO System

Either a single-pass or a tw

o-pass RO
system operating at 90%+ overall
recovery. The RO system is preceded
by cartridge filtration and a
degasification step. Optional CIP

System for RO cleaning.

MOD-6 – Rinse Reclaim / Recycle

Last rinse water from the cold and hot
UPW manufacturing operations are
diverted to this module for treatmen
and reuse. The heart of this process is
a patented reverse osmosis step, with
overall recovery greater than 90%.

MOD-5 – Hot UPW

A side stream of polished (pre-UF) wa­ter from Module 4 is diverted as feed
to this module. Product Water is
brought to temperature before going
through a hot UF step. The UF perme­ate then goes to the plant for con­sumption

MOD-4 – Polishing Loop / Cold UPW

Product water from Module 3 (above)
is collected in a blanketed storage
tank. A TOC reducing UV and cooling
heat exchanger serve as a precurso
to polishing mixed beds and a final
cold ultrafiltration (UF) step.

MOD-7 – Support Equipment

Miscellaneous system support opera­tions include necessary regeneration
storage tanks and transfer pumps.
