System recovery sets how concentrated your reject stream becomes. Move the slider to see the concentration factor and scaling-risk band for a brackish RO system.

Concentration factor (1 ÷ (1 − recovery))
25%
Reject / concentrate stream
At a feed of
ppm TDS, the concentrate approaches 12,000 ppm.
Concentration factor = 1 ÷ (1 − recovery), per American Membrane Technology Association guidance; most brackish water RO/NF systems run at 75–85% recovery. Actual scaling depends on specific ions (CaCO₃, CaSO₄, BaSO₄, SrSO₄, silica) and antiscalant dosing. Blue Membrane Z1 elements are rated to a 600 psi maximum and SDI ≤ 5.
