Theory 055/Water & Sanitation
Recovery Is a Saturation Ratio
The claim
Desalination energy is set by recovery ratio relative to saturation concentration rather than by salinity alone.
01The mechanism
Energy rises steeply as concentrate approaches saturation because osmotic pressure diverges.
02Predictions
- P1Energy should track the ratio.
- P2Higher salinity should require lower recovery for the same energy.
03Refutation
Energy tracking salinity alone would remove the recovery term.
