What can reverse osmosis effectively remove in water treatment?

Reverse osmosis (RO) is a highly effective water treatment technology primarily used to remove a wide range of dissolved solids, organic compounds, and other contaminants from water. In this context, the focus is on total organic carbon (TOC) and conductivity levels, which are important parameters in water treatment.

Choosing the option that states less than 0.5 mg/L TOC and 250 mg/L conductivity suggests that this level of performance aligns with the capabilities of reverse osmosis systems. RO can significantly reduce the levels of organic carbon in treated water, often achieving removals that bring TOC concentrations down to very low levels. The lower the TOC, the better the water quality, which is why specifying less than 0.5 mg/L is indicative of high RO efficiency.

Additionally, conductivity serves as a measure of the concentration of dissolved ions in water. The ability of RO membranes to remove various ions from water means that a conductivity level of 250 mg/L is well within the acceptable range for RO systems, as they can typically reduce total dissolved solids to lower than this threshold, ensuring treated water quality is enhanced.

The selected option effectively outlines the capacity of reverse osmosis to achieve low levels of both TOC and conductivity, demonstrating its role in
