The impacts of multivalent ions and organic substances on the energy generation efficiency of Reverse Electrodialysis (RED) devices were investigated in terms of uphill transport and membrane fouling. The results showed that the maximum power density was obtained when the 0.5 mol/L NaCl solutions was used as the feeding solution of the RED device. However, the power densities decreased by 72.45%, 68.82%, and 72.14%, respectively, as the feeding solutions were switched to 0.5 mol/L multivalent salt (MgCl2, CaCl2 and Na2SO4) solutions. By adding organic foulantssodium alginate (SA) into the multivalent salt solutions, the power density was enhanced with the increase of SA concentrations and reached a maximum level with addition of 30 mg/L SA, and then was gradually decreased when SA concentration was further raised. The NaCl solutions exerted minor influences on the adsorption of SA molecules onto cationexchange membranes. In contrast, the mixture of NaCl and MgCl2 obviously exacerbated the adhesion between SA molecules and cationexchange membranes
