While both are powerful, NF is often the preferred technology when the goal is not complete demineralization. Its main advantages include:
-
Higher Water Flux and Lower Energy Consumption: Because NF membranes are not as "tight" as RO membranes, they require significantly lower operating pressures. This translates to lower energy costs (often 15-30% less) and a higher flow rate for the same system size.
-
Better Mineral Retention: NF allows beneficial minerals like potassium and low levels of sodium to remain in the water. This results in tastier, more balanced drinking water without the "flat" taste sometimes associated with RO-treated water. Retaining some minerals also makes the water less corrosive to distribution pipes.
-
Reduced Brine Disposal: NF rejects fewer salts than RO, resulting in a lower volume of concentrated brine waste. This makes disposal easier and more environmentally friendly.
In short, if you don't need to remove every single dissolved solid (like converting seawater to freshwater), NF offers a more energy-efficient and cost-effective solution.
