GE’s AquaSel* System

A Non-Thermal Brine Concentrator (NTBC) – design and
performance to meet sustainability targets

Table 1: Technology vs. Water Recovery

AquaSel NTBC systems can effectively treat
wastewater and recover 95% as water suitable for
reuse. In most cases providing water that is equiva­lent to the raw water that the plant is currently us­ing. Some of the targeted uses:

Water scarcity, higher water costs and stringent
regulations are driving a behavioral change in con­sumers and industry to optimize the way we use
water. GE’s AquaSel systems offer the ability to min­imize the water footprint and achieve near Zero­Liquid Discharge recoveries with a cost effective,
sustainable process.

 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.

The AquaSel product line leverages GE’s know-how
and leadership in thermal evaporation and electro­lytic separations. The combination of these technol­ogies removes the barriers to water recovery due to
inorganic scale fouling. Prevalent desalination tech­nologies like reverse osmosis (RO) and electrodialy­sis reversal (EDR) can be limited by such scaling
when trying to go beyond 70% to 80% water recov­ery. Table 1 shows the typical water recovery for
technologies in challenging waters with strong
scale potential.

Water is critical

Are you faced with any of the following scenarios?

 Lack of available water to expand capacity
 Reached limit on wastewater discharge
 Unreliable water source
 Forced to decrease water consumption

Figure 1: AquaSel general layout (for reference only)

The innovative AquaSel NTBC technology (shown in
Figure1) can augment the water yield of your exist­ing equipment to achieve and overall 99+% recov­eries.

Costs are critical

Decrease your wastewater volume 10 to 50 times
and substantially reduce your fresh water intake
without having to boil the water to make it suitable
for reuse. See Figure 2 for a comparison of water
recoveries for traditional vs. AquaSel systems.

If you are faced with high total water costs (feed
and discharge), the thousands of gallons of water
saved per year by using GE’s AquaSel system will
net savings to the plant.
