``New`` countercurrent demineralization techniques are carving a place in water treatment
This article describes how supplementing older treatment methods with modern advancements creates water treatment technology greater than the sum of its parts. Water treatment technology has rapidly advanced in recent years to where a myriad of options are now available for producing makeup water for utility boilers. Some of the newer methods include two-pass reverse osmosis (RO), RO followed by mixed-bed demineralization and triple-membrane treatment consisting of ultrafiltration, electrodialysis and RO. All of these techniques have performed well in various applications. A technique that is gaining attention is packed-bed, counter-currently regenerated demineralization. This process combines ion exchange with advanced regeneration methods in a system that produces water of significantly better quality than that of conventional cation/anion units.
