Abstract

The procedure for obtaining analytical design equations for reverse osmosis desalination with spiral wound modules under turbulent as well as laminar flow conditions are reviewed. Predictive accuracy of such equations developed recently, decreases as the fractional solvent recovery increases and the membrane solute rejection decreases. For turbulent flow conditions, an additional design equation has been developed to correct the bulk solute concentration due to imperfect membrane rejection. Significantly higher predictive accuracy has been achieved when this additional equation is incorporated in the scheme of simple design equations. (A)
