Developed as a standard benchtop unit, SUEZ Water UK’s Select edi 60 combines double-pass reverse osmosis (RO) and electro-deionization (EDI) technologies in a single compact system. This approach eliminates the need for conditioning cartridges and carbon dioxide pre-treatment filters, it reduces total dissolved solids (TDS), and offers improved energy efficiency. The water purification system operates efficiently with even the hardest of feed water sources, providing continuous and consistent volumes of water at the correct quality to the EDI cell. The configuration reduces TDS to extremely low levels.  With a single-pass RO there is typically a 96 to 98% reduction in TDS, while in a double-pass system, the remaining impurities are further reduced by 96 to 98%. This provides greater protection to the EDI cell, preventing scaling and helping to optimize its operating life. Additionally, the use of the hollow fiber gas transfer membranes allows dissolved carbon dioxide to be stripped efficiently from the water as it passes from the water phase into the gaseous phase across the fibers. The process is highly effective and is driven by air provided by an onboard mini air pump.
