High-efficiency RO process boosts recovery ratios, cuts cleaning frequency
If your water treatment operation requires ultrapure water and water recovery ratios greater than 90%, the HERO™* process from GE Water & Process Technologies can help. HERO* uses three steps before reverse osmosis (RO) to remove dissolved solids and other contaminants:
 |
Cation exchange to reduce average hardness leakage to <0.1 ppm (100 ppb)</td /> |
 |
Degasification to cut dissolved CO2 to <10 ppm, reducing scale buildup</td /> |
 |
Increased pH in the RO feed to achieve operational benefits. |
RO operation at high pH (10 to 10.5) results in:
 |
Virtual elimination of bacteria growth to stop bio-fouling |
 |
Continuous cleaning of the RO system |
 |
High anion rejection rates |
 |
Greater solubility of silica in the feed stream |
HERO* systems typically process 25 to 30 gallons/sq.ft./day and offer recovery rates of 90% to 98%. A two-pass high-pH RO system delivers these anion rejection rates: boron >99.4%; silica >99.97%; total organic carbon (TOC) >99%.
GE engineers can help you choose the membrane and operating mode that delivers the gas removal you need at the most affordable cost. Satisfied customers using GTM® systems include ST Microelectronics in France, Singapore and Phoenix, Arizona, USA; Motorola, Inc., in China and Phoenix; Seagate Technology in Singapore; and Sandia National Laboratories in Albuquerque, New Mexico, USA.
