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 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)
	Degasification to cut dissolved CO2 to <10 ppm, reducing scale buildup
	Increased pH in the RO feed to achieve operational benefits.

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%.
