How effective is the reverse osmosis method for improving water quality?
RO is very effective, with high levels of contaminant reduction (approx. 98%) for point-of-use water quality improvement. This is possible because the reverse osmosis membrane is comprised of microscopic pores which allow the pressurized water molecules, which are among the smallest molecules known to man, to pass through the membrane. Consequently, large molecules and compounds containing contaminants like those listed in this brochure can be left behind. There is also a very complex process involving dielectric interactions and other molecular forces that takes place at the surface of the RO membrane. This second mechanism is effective in rejecting or repelling charged mineral ions from passing through to the RO water product.
