説明
Using three composite membranes (NS-300, NTR-7450, NTR-729 HF), reverse osmotic permeation flux and solute rejection have been measured at 1.5 MPa, 10-60° C for pure water, 0.5% NaCl and 0.5% MgSO4 aqueous solution. The results showed that the permeation remarkably increases, but rejection Ra slowly decreases, with the increase of operating temperature.<BR>The relationship between hydraulic permeability Lp and operating temperature in reverse osmotic separation have been theoretically derived using the solution-diffusion model. Introducing the temperature coefficient M defined by authors, the dependency of permeation on operating temperature can be expressed as following theoretical equation, lnLp (T) =lnLp (T) +Mln T/T0-Ps [Vs (T) /T-Vs (T0) /T0] (16) The dependence of rejection on temperature can be expressed as following experimental equation. Ra (T) =Ra (T0) (1+M/100) (T0/T-1) (19)
