GE’s AquaSel* System
A Non-Thermal Brine Concentrator (NTBC) – design and
performance to meet sustainability targets
Water scarcity, higher water costs and stringent
regulations are driving a behavioral change in con-
sumers and industry to optimize the way we use
water. GE’s AquaSel systems offer the ability to min-
imize the water footprint and achieve near Zero-
Liquid Discharge recoveries with a cost effective,
sustainable process.
The AquaSel product line leverages GE’s know-how
and leadership in thermal evaporation and electro-
lytic separations. The combination of these technol-
ogies removes the barriers to water recovery due to
inorganic scale fouling. Prevalent desalination tech-
nologies like reverse osmosis (RO) and electrodialy-
sis reversal (EDR) can be limited by such scaling
when trying to go beyond 70% to 80% water recov-
ery. Table 1 shows the typical water recovery for
technologies in challenging waters with strong
scale potential.
Table 1: Technology vs. Water Recovery
Technology
% Water Recovery
Reverse Osmosis
75% - 80%
Electrodialysis Reversal
80% - 85%
HERO*
85% - 90%
NTBC
93% - 96%
ZLD
99+%
AquaSel NTBC systems can effectively treat
wastewater and recover 95% as water suitable for
reuse. In most cases providing water that is equiva-
lent to the raw water that the plant is currently us-
ing. Some of the targeted uses:
NF, RO or EDR reject recovery.
High Recovery brackish water desalination
and/or NF/RO pretreatment.
High recovery tertiary wastewater reuse.
Cooling tower blow-down reuse.
Water is critical
Are you faced with any of the following scenarios?
