A: 60% of inlet water comes out as purified water, compared to as low as 5% in conventional RO (reverse osmosis) units, which means that lower end units can waste as much as 20 gallons per every gallon of purified water produced.

A: A thin film composite membrane is material containing tiny pores of a precise and uniform size that is used as an absorbent for liquids (also known as a molecular sieve,) this thin material is then constructed in the form of a film from two or more layered materials. Membranes used in reverse osmosis are typically made out of polyimide, chosen primarily for its permeability to water and relative impermeability to various dissolved impurities including salt-ions and other small, un-filterable molecules.

A: TFC membranes have a longer life span lasting about three to five years In addition, TFCs have a removal percentage between 94% and 99%, versus CTAs removal percentages of 86% to 94%.
