The RO treatment unit should specify the typical or nominal cation and anion rejection rates for the thin film membrane which would be either a cellulose acetate membrane or a cellulose triacetate membrane.
That now more heavily contaminated waste water must be appropriately disposed of. If a GAC filter is installed as a pre-filter on a source that is not chlorinated, it is likely that bacteria may regrow on the filter and membrane; it may be wise to install the GAC filter as a post filtration unit.
A GAC filter is needed for systems that have chlorinated water and the RO unit is using a thin-film composite membrane. Prefiltration and then Post filtration with 0. And, for general municipal water supplies, RO can filter out the most concerning contaminants like lead, arsenic, and other heavy metals, as well as troublesome dissolved hard minerals.
For large homes or businesses, this may not be a reliable or dependable solution for the long term.
